Diseases do Not Announce Their Arrival: Understanding and Preventing Poultry Diseases

In poultry farming, diseases pose a silent but ever-present threat to your flock. For most rural poultry farmers, the scourge of disease can lead to devastating consequences, ranging from financial losses to the eventual closure of operations. This article aims to educate poultry farmers on the causes, warning signs, and practical steps to mitigate poultry diseases effectively. The Heavy Cost of…

I want to make a post to inform people about the current situation with the bird flu (/avian flu/H5N1) outbreaks.

I don't want to cause panic but do want to spread information.

This is especially important if you live in an area that has a news system you don't trust to give accurate, timely, or honest news about something like a possible new pandemic, use your own judgement.

If that applies it is going to be very important to make sure you stay informed and follow these H5N1 outbreaks yourself and know how to best protect yourself.

I am no expert, but I do know a good bit about disease and influenza in particular, and have been following the H5N1 outbreaks as they've been happening, so under the cut I'm going to do my best to inform everyone I can.

Please stay safe, stay informed, and spread information, not germs.

What's bird flu and why do I care? (What's bird flu and why do I care?)

Avian flu and bird flu mean the same thing, an influenza virus that (primarily) infects birds. H5N1 denotes a specific strain of avian influenza. H5N1 can spillover (when a pathogen spreads from it's normal host organism to a new host organism) from animals to humans.

How could I get H5N1? (How could I get H5N1?)

Human to human transmission has not been observed yet (12/1/24) during this current outbreak. You can get this from contact with wild birds, especially water fowl, domestic birds, cattle, pigs, horses, dogs, and bats. It is also possible to get from raw (unpasteurized) milk and undercooked meat from infected animals.

What's the big deal then? (What's the big deal then?)

The common flu is not very pathogenic. How pathogenic something is determines how sick something makes the host, something that is highly pathogenic can cause severe disease. H5N1 is considered a HPAI, Highly Pathogenic Avian Influenza.

H5N1 is also a Type A influenza virus, most known Type A influenza viruses can infect birds. There is one Type A human flu in circulation at the moment, however it isn't very prevalent.

"IAV poses a significant risk of zoonotic infection, host switch, and the generation of pandemic viruses. IAVs can infect humans and a variety of animals, such as pigs, horses, marine mammals, cats, dogs, and birds (S1)."

IAV - Influenza A Viruses | Zoonotic infection - when an infectious disease of a non-human host infects a human host | Host switch - when a cross-species transmission of a pathogen can lead to successful, stable, and continuous infections

Every species the flu infects, the more strains that pop up under a sub-type IAV, the possibility for recombination increases. "Recombination occurs when at least two viral genomes [or strains] co-infect the same host cell and exchange genetic segments (S2)."

The flu is pretty good at recombination, when given the chance. It is also really good at mutating, and fast. If there were to be a recombination event and a new strain evolved (this would be called an antigenic shift) that was highly pathogenic, highly infectious (good at spreading, which H5N1 is), that could then infect humans and cause human-to-human transmission we might have a pandemic on our hands. This has not shown signs of happening during this outbreak*, this is what to look out for.

This (a recombination event) is what caused the 1918 pandemic during WW1. This pandemic killed an estimated 50 to 100 million people in 1918, in a world with a population of around 2 billion. 7.1 million died of COVID 19, as of 11/9/24 (S3), from a population of around 8 billion.

We know more, we are prepared, it's not guaranteed to happen, and it's not guaranteed to be as bad. But the possibilities are endless and it's extremely important to be prepared and stay informed.

So what do I do? (So what do I do?)

Again, stay informed, and that might mean checking independent news sources, the CDC website, and more, to keep yourself updated, especially if you know your local news won't do it for you. You should also familiarize yourself with the symptoms of influenza, if you have it, stay home.

Keep yourself safe, we had a pandemic already, you know the drill. Cover your nose and mouth when sneezing/coughing, wash your hands, sanitize your hands, and get your flu shot. And, in addition, avoid contact with wild birds, poultry, pigs, and cattle if you can.

In the event that this gets worse, social distancing is very important, being outdoors, wearing a mask, and all the stuff above, you can shed the virus for around a week before you start feeling bad. Keep yourself safe and don't infect anyone else.

If that doesn't sound like it'll do much, I promise you it does. Those are all classified NPI's (non-pharmaceutical interventions) and even epidemiologists were shocked at their impact and importance during the COVID-19 pandemic. They did work, and they were incredibly effective—as long as they were carried out.

I don't want to cause panic or worry anyone, but that is how information ends of suppressed. I want to make everyone aware of what we might face so that we can fight it and be strong and stay safe.

If anyone has any questions, wants any clarification, any corrections, or wants to know some good places to learn more about this stuff please don't hesitate to contact me (@'s, dm's, or asks), I will answer as best I can.

A nationwide recall of meat and poultry products potentially contaminated with listeria has expanded to nearly 12 million pounds and now includes ready-to-eat meals sent to U.S. schools, restaurants and major retailers, federal officials said. The updated recall includes prepared salads, burritos and other foods sold at stores including Costco, Trader Joe’s, Target, Walmart and Kroger. The meat used in those products was processed at a Durant, Oklahoma, manufacturing plant operated by BrucePac. The Woodburn, Oregon-based company sells precooked meat and poultry to industrial, foodservice and retail companies across the country. Routine testing found potentially dangerous listeria bacteria in samples of BrucePac chicken, officials with the U.S. Agriculture Department said. No illnesses have been confirmed in connection with the recall, USDA officials said. The U.S. Centers for Disease Control and Prevention has not launched an outbreak investigation, a spokesperson said. The recall, issued on Oct. 9, includes foods produced between May 31 and Oct. 8. The USDA has posted a 342-page list of hundreds of potentially affected foods, including chicken wraps sold at Trader Joe’s, chicken burritos sold at Costco and many types of salads sold at stores such as Target and Walmart. The foods were also sent to school districts and restaurants across the country. The recalled foods can be identified by establishment numbers “51205 or P-51205” inside or under the USDA mark of inspection. Consumers can search on the USDA recall site to find potentially affected products. Such foods should be thrown away or returned to stores for refunds, officials said. Eating foods contaminated with listeria can cause potentially serious illness. About 1,600 people are infected with listeria bacteria each year in the U.S. and about 260 die, according to the U.S. Centers for Disease Control and Prevention. Listeria infections typically cause fever, muscle aches and tiredness and may cause stiff neck, confusion, loss of balance and convulsions. Symptoms can occur quickly or to up to 10 weeks after eating contaminated food. The infections are especially dangerous for older people, those with weakened immune systems or who are pregnant. The same type of bacteria is responsible for an outbreak tied to Boar’s Head deli meat that has killed at least 10 people since May.

By prohibiting any new public releases of health information, the Trump administration has brought to a halt the work of a variety of public health coordination committees, including those on the widening bird flu outbreak, which are required by law to submit their meetings to the public record in The Federal Register. Since they can't release their meetings, they can't meet at all.

The new stricture applies to messages to email groups and to social media posts, and included a ban on announcements to The Federal Register, without which many official processes cannot continue. Some notices sent by the Biden administration in its final week were quickly withdrawn.

The cancellations and communications crackdown sent a chill through employees of the Centers for Disease Control and Prevention and the broader scientific community. The directive was first reported by The Washington Post. 

The fallout was immediate.

Officials at the C.D.C. had been prepared to publish an issue of the influential Morbidity and Mortality Weekly Report on Thursday that included several items related to the widening bird flu outbreak on dairy and poultry farms.

The weekly reports have been called the “holiest of the holy,” a crucial means of communication about developments in public health. This week’s publication is now held up as a result of the order, according to two federal health officials who spoke on condition of anonymity because they were not authorized to speak publicly.

[collapsedsquid]

In the U.K., the Health Security Agency recently raised its threat level to 4 out of 6, the stage immediately before large-scale human outbreaks. In Europe, countries are proactively vaccinating dairy and poultry workers against infection, with 15 nations already securing a total of 40 million doses through the European Commission. In the United States, despite having a stockpile of those vaccines, we are not distributing them, instead focusing on standing up voluntary supplies of seasonal flu vaccines to frontline workers. (The hope is that this will prevent animal infections of human flu that might aid in the further mutation of H5N1.) The Centers for Disease Control and Prevention has cited the low number of cases to justify its inaction, but it has also moved remarkably slowly to promote the kind of widespread surveillance testing that could actually identify cases. Only recently has the agency begun to mobilize real funding for a testing push, after a period of months in which various federal groups batted around responsibility and ultimate authority like a hot potato. And as was the case early in the Covid-19 pandemic, the C.D.C.’s preferred test for bird flu “has issues.” Three months into the outbreak, only 45 people had even been tested; six weeks later, the total number of people tested had grown only to “230+.” [...] Most farms aren’t supplying N95 masks, goggles or aprons to protect workers, either, and when Amy Maxmen of KFF News surveyed farm workers to ask why they weren’t getting tested, “no one had heard of bird flu, never mind gotten P.P.E. or offers of tests,” she reported. “One said they don’t get much from their employers, not even water. If they call in sick, they worry about getting fired.” Last month, a crew was deployed to slow the spread of the disease by killing every last chicken of 1.78 million on a large Colorado farm where H5N1 had broken out and six of the workers contracted the virus, partly because the gear they’d been provided was hard to use in the punishing 104-degree heat. In June, Robert Redfield, former director of the C.D.C., echoed many epidemiologists in predicting that “it’s not a question of if, it’s more of a question of when we will have a bird flu pandemic.” In July, Brown’s Jennifer Nuzzo warned that the steady beat of new cases “screams at us that this virus is not going away.” Tulio de Oliveira, a bioinformatician who studies global disease surveillance, marveled that the American effort to track the spread of the disease was absolutely amateurish and the country’s apparent indifference “unbelievable.”

Yesterday, health officials in Louisiana announced that a patient who was hospitalized with severe bird flu in December has died. The individual contracted bird flu after exposure to a backyard flock and wild birds. It is the first death recorded in the United States attributed to H5N1, or avian influenza.

The person was over the age of 65 and reportedly had underlying medical conditions. The Louisiana Health Department has not released any more details about the patient.

A total of 66 people in the US tested positive for bird flu in 2024, according to the Centers for Disease Control and Prevention. In all of the other cases, people developed mild symptoms and made a full recovery. But the Louisiana case is a stark reminder that avian flu can be dangerous. And as the number of human infections rises, health experts worry about more cases of severe illness—and potentially more deaths.

“This is an ongoing game of Russian roulette,” says physician Nahid Bhadelia, founding director of the Center on Emerging Infectious Diseases at Boston University. “The more virus there is in our environment, the more chances there are for it to come into contact with humans.” It was only a matter of time before bird flu turned deadly, she says.

The US is in the middle of an H5N1 outbreak that shows no signs of stopping. The virus has infected more than 130 million birds, including commercial poultry, since January 2022. In April 2024 it spilled into dairy cows for the first time. Though not fatal for cows, the virus has sickened more than 900 dairy herds in 16 states.

Most people who come down with bird flu are farm workers or others who have direct contact with sick animals. Of the 66 confirmed infections in the US last year, 40 had exposure to dairy cows, while 23 had exposure to poultry and culling operations. In the three other cases, the exact source of exposure is unknown.

Since 2003, more than 850 human cases of H5N1 bird flu have been reported outside the United States, and about half of those have resulted in death. In a statement released Monday, the CDC said a death from H5N1 bird flu “is not unexpected because of the known potential for infection with these viruses to cause severe illness and death.” Federal health officials say the risk of getting bird flu remains low for the general public, and there is no evidence that the virus is spreading from person to person anywhere in the country.

One of the puzzling aspects of the current US outbreak is why all the human infections until now have resulted in mild illness. “It could be that they're young, healthy people,” says Jennifer Nuzzo, director of the Pandemic Center and a professor of epidemiology at Brown University. “It could be that the way they're being exposed is different from how we've historically seen people get infected. There are a number of hypotheses, but at this point they're all just guesses.”

Nuzzo says it’s very possible that the Louisiana patient’s preexisting health conditions contributed to the severity of their illness, but also points to the case of a teenager in Canada who was hospitalized with bird flu in November.

The 13-year-old girl was initially seen at an emergency department in British Columbia for a fever and conjunctivitis in both eyes. She was discharged home without treatment and later developed a cough, vomiting, and diarrhea. She wound up back in the emergency department in respiratory distress a few days later. She was admitted to the pediatric intensive care unit and went into respiratory failure but eventually recovered after treatment. According to a case report published in the New England Journal of Medicine, the girl had a history of mild asthma and an elevated body-mass index. It’s unknown how she caught the virus.

“What that tells us is that we have no idea who is going to develop mild illness and who is going to develop severe illness, and because of that we have to take these infections very seriously,” Nuzzo says. “We should not assume that all future infections will be mild.”

There’s another clue that could explain the severity of the Louisiana and British Columbia cases. Virus samples from both patients showed some similarities. For one, both were infected with the same subtype of H5N1 called D1.1, which is the same kind of virus found in wild birds and poultry. It’s different from the B3.13 subtype, which is dominant in dairy cows.

“Right now, the question is, is this a more severe strain than the dairy cattle strain?” says Benjamin Anderson, assistant professor of environmental and global health at the University of Florida. So far, scientists don’t have enough data to know for sure. A handful of poultry farm workers in Washington have tested positive for the D1.1 subtype, but those individuals had mild symptoms and did not require hospitalization.

“In the case of the Louisiana infection, we know that person had comorbidities. We know that person was an older individual. These are factors that contribute to more severe outcomes already when it comes to respiratory infections,” Anderson says.

In the Louisiana and British Columbia cases, there’s evidence that the virus may have evolved in both patients to produce more severe illness.

A CDC report from late December found genetic mutations in the virus taken from the Louisiana patient that may have allowed it to enhance its ability to infect the upper airways of humans. The report says the changes observed were likely generated by replication of the virus throughout the patient’s illness rather than transmitted at the time of infection, meaning that the mutations weren’t present in the birds the person was exposed to.

Writing in the New England Journal of Medicine, the team that cared for the Canadian teen also described “worrisome” mutations found in her viral samples. These changes could have allowed the virus to more easily bind to and enter cells in the human respiratory tract.

In the past, bird flu has rarely been transmitted from person to person, but scientists worry about a scenario where the virus would acquire mutations that would make human transmission more likely.

For now, people who work with birds, poultry, or cows, or have recreational exposure to them, are at higher risk of getting bird flu. To prevent illness, health officials recommend avoiding direct contact with wild birds and other animals infected with or suspected to be infected with bird flu viruses.

The CDC study titled Highly Pathogenic Avian Influenza A(H5N1) Virus Infections in Humans was just published in The New England Journal of Medicine:

BACKGROUND Highly pathogenic avian influenza A(H5N1) viruses have caused widespread infections in dairy cows and poultry in the United States, with sporadic human cases. We describe characteristics of human A(H5N1) cases identified from March through October 2024 in the United States. METHODS We analyzed data from persons with laboratory-confirmed A(H5N1) virus infection using a standardized case-report form linked to laboratory results from the Centers for Disease Control and Prevention influenza A/H5 subtyping kit. RESULTS Of 46 case patients, 20 were exposed to infected poultry, 25 were exposed to infected or presumably infected dairy cows, and 1 had no identified exposure; that patient was hospitalized with nonrespiratory symptoms, and A(H5N1) virus infection was detected through routine surveillance. Among the 45 case patients with animal exposures, the median age was 34 years, and all had mild A(H5N1) illness; none were hospitalized, and none died. A total of 42 patients (93%) had conjunctivitis, 22 (49%) had fever, and 16 (36%) had respiratory symptoms; 15 (33%) had conjunctivitis only. The median duration of illness among 16 patients with available data was 4 days (range, 1 to 8). Most patients (87%) received oseltamivir; oseltamivir was started a median of 2 days after symptom onset. No additional cases were identified among the 97 household contacts of case patients with animal exposures. The types of personal protective equipment (PPE) that were most commonly used by workers exposed to infected animals were gloves (71%), eye protection (60%), and face masks (47%). CONCLUSIONS In the cases identified to date, A(H5N1) viruses generally caused mild illness, mostly conjunctivitis, of short duration, predominantly in U.S. adults exposed to infected animals; most patients received prompt antiviral treatment. No evidence of human-to-human A(H5N1) transmission was identified. PPE use among occupationally exposed persons was suboptimal, which suggests that additional strategies are needed to reduce exposure risk. (Funded by the Centers for Disease Control and Prevention.)

Won't someone think of the egg prices!

By John Lindt

KERN COUNTY – The price of eggs is often used as a barometer for the economy, but this fall’s high prices are not the work of market factors, but rather migratory flights.

Avian flu is spreading along the path of birds’ southern migration for winter across California. As of Nov. 12, the U.S. Department of Agriculture (USDA) reported that a large egg ranch in Kern County has been impacted by bird flu resulting in the destruction of 2.15 million egg layers. This is the first case of HPAI in Kern County during the 2022-24 bird flu outbreak as it spread south heading into winter. Kern County is home to some of the state’s largest egg ranch operations.

The same day USDA also announced that avian flu hit two Fresno County poultry ranches, one a broiler ranch resulting in the killing of 237,700 chickens being prepped for meat and a turkey ranch requiring the destruction of 34,800 toms, or male turkeys. The news follows recent reports about avian flu spreading to Kings County poultry ranches resulting in the loss of over half a million birds and at another Fresno ranch. On Nov. 14, USDA added three more poultry ranches to the list of affected including one in Merced County, a turkey ranch with the loss of 53,200 birds and another one in Fresno County.

The locations of the poultry ranches are not far from the Pacific flyway, a major migratory route in the Western United States. In the case of Kern County, the egg ranch was close to the Kern Wildlife Refuge as well as nearby dairies. This is worrying observers that there appears to be a connection between all three vectors for the rapidly mutating virus.

Northern California poultry operations have been hard hit as well. Nationwide, outbreaks have claimed more than 21 million hens, so far in 2024.

Egg Prices In California the impact on egg prices has been significant.

On Nov. 13, the USDA reported that a dozen large, white cage-free eggs cost about $5.26 per dozen in California. This is according to USDA market data for the week of Nov. 8. USDA says this is a “benchmark” price. The price is up from $2.81 a month earlier. That is almost double the benchmark, but may not reflect retail.

The last time California eggs were this high was in February when California egg prices – cage-free egg prices – peaked at $5.59 per dozen.

The cases of infected birds correspond with fall bird migrations that are spreading the virus throughout the state. Detections are higher in fall and spring as wild birds spread the virus when they migrate. This year the bird flu has taken its toll with the outbreak of H5N1, a highly transmissible and fatal strain of avian influenza, or bird flu. The outbreak started in early 2022 and rapidly grew into the largest bird flu outbreak in U.S. history.

Most recently, outbreaks affecting more than 2.84 million egg layers were reported in October at commercial facilities in Oregon, Washington and Utah, according to the Centers for Disease Control and Prevention (CDC).

As of Nov. 8, the virus has affected over 105.2 million birds in the U.S. since January 2022, according to the CDC. The California egg shortage will likely have a pocketbook impact on holiday baking activity as the nation prepares for Thanksgiving; however, a recent USDA analysis suggests consumers may not see a huge jump.

“Large volume grocery retailers across the nation have launched their shell egg feature campaigns targeting holiday demand at relatively attractive price levels. Much of this is attributable to changes in the way shell eggs are being marketed with an increasing share (estimated at over half of all shell egg volume sold at retail) tied to production cost agreements not prone to fluctuation common in formula trading.”

There are about 378.5 million egg-laying chickens in the US. As of last year, there were 9.4 billion broiler chickens and 218 million turkeys processed, according to the USDA. Advocates note the high cost of the influenza just in the egg market. “With domestic sales of shell eggs and products amounting to seven billion dozen, consumers paid an incremental $15 billion as a result of the prolonged and uncontrolled infection.”

While bird flu is impacting poultry farms, another strain of the virus has impacted Central Valley dairies as well, spreading quickly since September to 291 dairy farms as of press time. Unlike poultry, dairy cows typically survive the virus, although milk production is expected to be impacted.

Avian flu is a worldwide phenomenon. In the past two weeks, the first cases of highly pathogenic avian influenza (HPAI) of the fall season have been reported in Albania, Great Britain, Romania, and now regions of Germany and Ukraine.

Despite the increase in US egg prices this holiday season, turkey prices are down from last year when supply was also affected by bird flu. Across the country, a 15-pound turkey costs an average of $31.16 ($2.08 per pound) in 2024, compared with $35.40 ($2.36 per pound) in 2023. That price reduction represents a price decrease of 12% from last year to now,” a report said. The lower price comes even as a U.S. Department of Agriculture report showed turkey production dipped more than 6% compared to this time last year.

Hen and Hoof The spread of this strain of the virus appears to be affecting both the Central Valley poultry and dairy industries at the same time.

Just before Sept. 1 there were no reports of the virus in the Valley’s dairy industry. But as of Nov. 15, there are almost 300 diaries, mostly in Tulare and Kings Counties, impacted with new ones being added every day.

The Valley poultry industry has been on a similar viral timeline which coincides with the annual bird migration along the Pacific flyway that happens each fall. H5N1 largely infects wild birds, with waterfowl such as ducks and geese being the natural reservoirs for H5N1 viruses. Most H5N1 viruses are highly pathogenic avian influenza, meaning spillovers into other bird populations can lead to high mortality rates, including domesticated poultry.

A compounding factor for the spread of the virus is that both livestock are often on land located right next door or just down the road. The Central Valley is home for both industries with animals, transported in and out, and service vehicles going in and out of these large facilities every day.

The industry website Egg-News this week pointed out that research shows that the infections can be transmitted over a distance of up to a mile while attached to dust particles. Fall is harvest for a number of crops, including the nut industry, sending up plumes of dust in the Valley sky, at times associated with winds.

Egg-News points out that dairy cow-associated H5N1 viruses have jumped back into wild birds, and recent outbreaks in domestic poultry resembled H5N1 in dairy cows.

In an editorial Egg-News said “APHIS Needs a New Approach to Control HPAIr.” They recommend that USDA’s Animal and Plant Health Inspection Service (APHIS) adopt vaccination as a disease control strategy for bird flu, with promising results from clinical trials. In May 2023, the U.S. authorized the vaccination of California condors against a type of avian flu.

Also, the USDA has approved field trials to test vaccines that could prevent dairy cows from getting the H5N1 strain of bird flu. The USDA approved the first field trials for the vaccine in September 2024. The USDA’s Center of Veterinary Biologics (CVB) is overseeing the trials. At least 24 companies are working on the vaccine, including Zoetis and Merck Animal Health.

If vaccines can save the U.S. poultry and dairy industry over the next year, the industry may have to worry about who heads up the U.S. Department of Health and Human Services (HHS), the agency which authorizes vaccines for animals and humans. Nominee Robert F. Kennedy, Jr. has made it clear he is anti-vaccine but has yet to comment on the use of vaccines in agriculture if he is confirmed for the role.

Brazil confirms first Newcastle disease case in 18 years

Officials at Brazil’s Agriculture Ministry have confirmed an outbreak of Newcastle disease at a commercial poultry farm in Anta Gorda, a municipality in Rio Grande do Sul, the country’s southernmost state. 

The government said the farm was immediately quarantined once the case was under investigation. “A complementary investigation will also be carried out within a 10-kilometer radius around the outbreak area, in addition to other necessary measures as per the epidemiological assessment,” the Agriculture Ministry said in a statement.

Newcastle disease is a highly contagious and often severe disease found worldwide that affects birds, including domestic poultry, according to the World Organization for Animal Health. The last confirmed cases in Brazil were recorded in 2006 in the states of Amazonas, Mato Grosso, and Rio Grande do Sul.

Control measures include strict isolation or quarantine of outbreaks and the destruction of all infected and exposed birds.

Avian flu is wreaking havoc in poultry farms and dairy cattle -- and public health experts are worried that the virus could mutate to spread among humans.1,2

Left unchecked, avian flu could result in the next deadly human pandemic. In order to prevent a public health catastrophe and reduce the impact on humans and animals, we need to take much more aggressive action.

Take action to help keep bird flu under control before it begins to pose a bigger threat to our health.

How can we reduce the risk of avian flu making the leap to humans and fueling another pandemic?

We're urging the Department of Health and Human Services (HHS) and the U.S. Department of Agriculture (USDA) to increase testing and monitoring, develop a vaccination program, and take prudent measures to protect the health of people working directly with impacted animals.

The first case of H5N1 bird flu in humans this year was confirmed in April. By November, the total number of confirmed human cases had grown to at least 52.3

Now is our chance to get this under control before it gets any worse -- but we need our public health agencies to take the right steps to make it possible.

Add your name to urge HHS and USDA to act now to reduce the spread of bird flu to humans.

These straightforward steps could make a huge difference for our health.

First, USDA and HHS should increase surveillance for bird flu in all food-producing animals. We can better track and control this disease if we have reliable data about where it is appearing and spreading in our food system. New federal rules requiring milk to be tested for bird flu on dairy farms are a great first step, but more testing and monitoring are needed.4

The agencies should also provide protective equipment and vaccines to workers who work directly with impacted animals. This will help form a shield that could stop the virus from making the leap to humans.

Developing and implementing a vaccination program for food-producing animals will also be an important way to control the spread of H5N1 bird flu.

And of course, supporting local pasture-based farms with high standards for animal welfare will make our entire food system healthier. Animals kept in clean, healthy environments are less likely to pass disease among each other, or to farm workers.

We can stop the next deadly pandemic before it starts -- but the solution has to start right now. Add your name to our petition to HHS and USDA today.

The Truth About Animal Vaccines: Debunking Myths in Livestock Health

In today’s fast-paced agrospace, misleading information can spread quickly, both online and offline. One particular misconception that has emerged is the concept of “organic vaccines” for livestock. While plants have valuable pharmacological properties, they cannot be transformed into vaccines. It’s important for farmers and livestock owners to separate fact from fiction to protect their…

How many American deaths will he be responsible for this time?

[follow-up-news]

A salmonella outbreak linked to recalled eggs has sickened 65 people in nine states, U.S. health officials said. As of Friday, 24 people had been hospitalized, according to the Centers for Disease Control and Prevention. No deaths were reported. The recalled eggs came from Milo’s Poultry Farms and were distributed to Wisconsin, Illinois and Michigan, the CDC said. Eggs labeled “Milo’s Poultry Farms” and “Tony’s Fresh Market” are subject to the recall, which was announced on Friday, because they may be contaminated with salmonella, a bacteria that can cause serious and sometimes fatal infections, the Food and Drug Administration said. The recall includes all carton sizes and expiration dates. People fell ill between May 23 and Aug. 10. Most of the illnesses are concentrated in Wisconsin and Illinois. People also reported illnesses in California, Utah, Colorado, Minnesota, Iowa, Michigan and Virginia. The actual number of sicknesses in the outbreak is likely much higher than the number reported, and may extend to other states, the CDC said.

Amid a deluge of executive actions, the Trump administration has directed federal health agencies to pauseexternal communications, such as regular scientific reports, updates to websites and health advisories, according to sources within the agencies.

The initial orders were delivered Tuesday to staff at agencies inside the US Department of Health and Human Services, including to officials at the US Food and Drug Administration, the US Centers for Disease Control and Prevention and National Institutes of Health, according to the Washington Post, which first reported the story.

The direction came without warning and with little guidance as to what exactly it covered, according to sources inside the affected agencies who asked not to be named because they were not authorized to share the information.

In a follow-up memo obtained by CNN on Wednesday, Acting Health Secretary Dr. Dorothy Fink provided additional details, including that the directive would be in effect through February 1.

The memo told health agency employees to have all documents and communications - including regulations, guidance, notices, social media, websites and press releases - reviewed and approved by a presidential appointee before issuing them. It also directed employees not to participate in any public speaking engagements without approval, and to coordinate with presidential appointees before issuing official correspondence to members of Congress or governors.

���As the new Administration considers its plan for managing the federal policy and public communications processes, it is important that the President’s appointees and designees have the opportunity to review and approve any regulations, guidance documents, and other public documents and communications (including social media),” Fink said in the memo.

The directive also told employees to notify higher-ups of any documents or communications that should be exempt either because they’re required by law or because they’re critical for health, safety or other reasons. Already Wednesday morning, the FDA sent out a communication about a safety warning added to the multiple sclerosis drug glatiramer acetate, which goes by brand names including Copaxone, for a “rare but serious allergic reaction.”

A source familiar with the directive said that while it wasn’t entirely unheard of for an incoming administration to ask for a pause to review information before it’s publicly released, the scope of the order appeared to be unusual. Another said there were no similar restrictions on communications issued at the beginning of the last two administrations, and said employees were fearful about their jobs.

America’s health agencies, including the CDC, FDA and the NIH, routinely release information on food recalls, drug and medical device approvals, as well as updates on evolving public health threats including natural disasters and infectious diseases. Many of the agencies have been closely tracking and reporting new information on the H5N1 bird flu outbreak, which is spreading in the nation’s poultry flocks and dairy cattle and among people who work with those animals.

“Not a day goes by when CDC isn’t tracking a potential threat to our health,” Dr. Richard Besser, president and CEO of the Robert Wood Johnson Foundation and former acting director of the CDC said in a statement. “Right now they are letting us know about bird flu in cows, birds, and people. Every time there is an outbreak involving a food, they let us know how to avoid getting sick. They let us know where diseases are occurring around the world that could affect our health here or if we travel. Cutting off communications from CDC puts our health at risk and prevents our doctors, nurses, and public health leaders in our communities from doing their jobs. I urge the administration to quickly lift the pause.”

US first bird flu death reported in Louisiana

The first case of death from avian influenza type H5N1 was recorded in the US state of Louisiana on Monday, the local health department’s press office reported.

The Louisiana Department of Health said in a statement:

“The patient was over the age of 65 and was reported to have underlying medical conditions. The patient contracted H5N1 after exposure to a combination of a non-commercial backyard flock and wild birds.”

The man was hospitalised and despite medical attention, died from the disease. This is the first and only human case of bird flu reported in Louisiana and the US.

While expressing condolences to the patient’s family, the Louisiana Department of Health assured the public that the risk of bird flu spreading to humans remains very low.

However, people who work with birds, poultry or farm animals, or spend time in wild bird habitats are at greater risk of infection.

In late December 2024, the US Centres for Disease Control and Prevention (CDC) was reported to have identified an avian flu mutation in a patient with the country’s first severe case.

According to the CDC, the identified mutation was not present in samples taken from the patient’s infected birds. The agency noted that the changes in the samples of the infected person were observed in one of the genes – haemagglutinin, which plays a key role in attaching to cells in the body of the virus carrier.
