The News

A highly lethal form of bird flu has been detected in Antarctic penguins for the first time. The virus, which is known as H5N1, was confirmed in a few gentoo penguins that were found dead in the Falkland Islands, according to the British territorys Department of Agriculture. Another few dozen gentoo penguins were reported sick or dead at the same location.

At least one suspected case has also been reported in king penguins in South Georgia, another British territory, according to the Antarctic Wildlife Health Network, which is part of the Scientific Committee on Antarctic Research.

The familiar black-and-white birds are facing numerous threats, including climate change, pollution and commercial fishing. Three Antarctic penguin species emperor penguins, southern rockhopper penguins and macaroni penguins are listed as vulnerable or near threatened.

Before H5N1 arrived in the Antarctic region last fall, highly pathogenic bird flu viruses had never been documented in the area before. That means that the penguins are likely to have little existing immunity. And because they breed in large, crowded colonies, once one penguin is infected, the virus could spread rapidly, causing mass mortalities. (As the virus spread through South America last year, Chile reported the deaths of thousands of Humboldt penguins.)

The extent of the viruss spread in Antarctic penguin populations remains unclear, and the king penguin cases have not yet been confirmed.

We have no conclusive evidence that king penguin populations in South Georgia have been impacted by the virus, Laura Willis, the chief executive of the government of South Georgia and the South Sandwich Islands, said in an email. We are monitoring the situation across the islands and apply a precautionary approach, which includes closing some sites to allow further investigations to take place.

First Bird Flu Deaths Reported In Antarctic Penguins - The New York Times

California

Highly contagious virus has particularly ravaged Californias Sonoma county, know as the Egg Basket of the World

Associated Press

Mon 29 Jan 2024 13.43 EST

Last month, Mike Weber got the news every poultry farmer fears: his chickens tested positive for avian flu.

Following government rules, Webers company, Sunrise Farms, had to slaughter its entire flock of egg-laying hens 550,000 birds to prevent the disease from infecting other farms in Sonoma county north of San Francisco.

Its a trauma. Were all going through grief as a result of it, said Weber, standing in an empty hen house. Petaluma is known as the Egg Basket of the World. Its devastating to see that egg basket go up in flames.

A year after the bird flu led to record egg prices and widespread shortages, the disease known as highly pathogenic avian influenza is wreaking havoc in California, which escaped the earlier wave of outbreaks that devastated poultry farms in the midwest.

The highly contagious virus has ravaged Sonoma county, where officials have declared a state of emergency. During the past two months, nearly a dozen commercial farms have had to destroy more than 1 million birds to control the outbreak, dealing an economic blow to farmers, workers and their customers.

Merced county in Central California also has been hit hard, with outbreaks at several large commercial egg-producing farms in recent weeks.

Experts say bird flu is spread by ducks, geese and other migratory birds. The waterfowl can carry the virus without getting sick and easily spread it through their droppings to chicken and turkey farms and backyard flocks through droppings and nasal discharges.

California poultry farms are implementing strict biosecurity measures to curb the spread of the disease. State veterinarian Annette Jones urged farmers to keep their flocks indoors until June, including organic chickens that are required to have outdoor access.

We still have migration going for another couple of months. So weve got to be as vigilant as possible to protect our birds, said Bill Mattos, president of the California Poultry Federation.

The loss of local hens led to a spike in egg prices in the San Francisco Bay Area over the holidays before supermarkets and restaurants found suppliers from outside the region.

While bird flu has been around for decades, the current outbreak of the virus that began in early 2022 has prompted officials to slaughter nearly 82 million birds, mostly egg-laying chickens, in 47 US states, according to the US Department of Agriculture. Whenever the disease is found the entire flock is slaughtered to help limit the spread of the virus.

The price of a dozen eggs more than doubled to $4.82 at its peak in January 2023. Egg prices returned to their normal range as egg producers built up their flocks and outbreaks were controlled. Turkey and chicken prices also spiked, partly due to the virus.

I think this is an existential issue for the commercial poultry industry. The virus is on every continent, except for Australia at this point, said Maurice Pitesky, a poultry expert at the University of California, Davis.

Climate change is increasing the risk of outbreaks as changing weather patterns disrupt the migratory patterns of wild birds, Pitesky said. For example, exceptional rainfall last year created new waterfowl habitat throughout California, including areas close to poultry farms.

In California, the outbreak has impacted more than 7 million chickens in about 40 commercial flocks and 24 backyard flocks, with most of the outbreaks occurring over the past two months on the North Coast and Central Valley, according to the USDA.

Industry officials are worried about the growing number of backyard chickens that could become infected and spread avian flu to commercial farms.

We have wild birds that are are full of virus. And if you expose your birds to these wild birds, they might get infected and ill, said Rodrigo Gallardo, a UC Davis researcher who studies avian influenza.

Gallardo advises the owners of backyard chickens to wear clean clothes and shoes to protect their flocks from getting infected. If an unusual number of chickens die, they should be tested for avian flu.

Ettamarie Peterson, a retired teacher in Petaluma, has a flock of about 50 chickens that produce eggs she sells from her backyard barn for 50 cents each.

Im very concerned because this avian flu is transmitted by wild birds, and theres no way I can stop the wild birds from coming through and leaving the disease behind, Peterson said. If your flock has any cases of it, you have to destroy the whole flock.

Sunrise Farms, which was started by Webers great-grandparents more than a century ago, was infected despite putting in place strict biosecurity measures to protect the flock.

The virus got to the birds so bad and so quickly you walked in and the birds were just dead, Weber said. Heartbreaking doesnt describe how you feel when you walk in and perfectly healthy young birds have been just laid out.

After euthanizing more than half a million chickens at Sunrise Farms, Weber and his employees spent the Christmas holiday discarding the carcasses. Since then, theyve been cleaning out and disinfecting the hen houses.

Weber hopes the farm will get approval from federal regulators to bring chicks back to the farm this spring. Then it would take another five months before the hens are mature enough to lay eggs.

He feels lucky that two farms his company co-owns have not been infected and are still producing eggs for his customers. But recovering from the outbreak wont be easy.

We have a long road ahead, Weber said. Were going to make another run of it and try to keep this family of employees together because theyve worked so hard to build this into the company that it is.

Half a million dead hens: avian flu outbreak forces US farmers to kill flocks - The Guardian US

Previous outbreaks have shown that penguins are highly vulnerable to the disease

One king penguin is suspected to have died from bird flu on South Georgia island in the Antarctic region, Guardian reported. If confirmed, it will be the first of the species killed by the highly contagious H5N1 virus in the wild.

Researchers have expressed concerns about the potentially devastating impact of the disease on remote penguin populations highlighting that the current breeding season could allow the virus to spread rapidly and cause ''one of the largest ecological disasters of modern times.''

The Antarctic was the only major geographical region in which high pathogenicity avian influenza virus had never previously been detected.Birds such as penguins that have never before been exposed to the virus would have no prior immunity, potentially making them more vulnerable.

King penguins, the second-largest penguin species in the world,at about 3 feet tall, can live for more than 20 years in the wild. Apart from the king penguin, a gentoo penguin also died from H5N1 at the same location. Another gentoo penguin has been confirmed to have died from H5N1 on the Falkland Islands, 900 miles (1,500km) west of South Georgia

Previous outbreaks in South Africa, Chile, and Argentina have shown that penguins are highly vulnerable to the disease, as over 500,000 seabirds in South America, including penguins, pelicans, and boobies have died from it.

Ed Hutchinson, a molecular virologist at the MRC-University of Glasgow Centre for Virus Research, said: ''The arrival of this H5N1 virus in the Antarctic towards the end of last year rang alarm bells because of the risk it posed to wildlife in this fragile ecosystem. And while it is very sad to hear reports of penguins dying it is unfortunately not at all surprising.''

Diana Bell, emeritus professor of conservation biology at the University of East Anglia, also voiced similar fears. She said, ''I'm just devastated, really as will everybody who cares about penguins and the Antarctic Given their colonial social organisation, you'd just wonder how quickly it would go through the colonies.''

The threat of avian flu adds to the existing pressures faced by pristine polar ecosystems. A study from 2018 predicted that king penguins in Antarctica could face extinction by the end of this century.

A few weeks back, a polar bear also died from H5N1, marking the first recorded case of this species.The bear was discovered in Utqiagvik, an area that's been hit hard by the current global outbreak.Polar bears are categorized as "vulnerable" on the International Union for Conservation of Nature (IUCN) red list of endangered species, primarily as a result of the diminishing sea ice.

The virus also poses a threat to humans, particularly those in contact with poultry.

First Penguins Die In Antarctic Of Deadly H5N1 Bird Flu Strain, Experts Raise Alarm - NDTV

The age of extinction

With confirmed or suspected cases in two Antarctic penguin species, researchers fear highly contagious virus could rip through colonies

At least one king penguin is suspected to have died from bird flu in the Antarctic. If confirmed, it will be the first of the species killed by the highly contagious H5N1 virus in the wild.

Researchers have previously raised alarm about one of the largest ecological disasters of modern times if bird flu reached remote Antarctic penguin populations. The birds are currently clustering together for breeding season, meaning the disease could rip through entire colonies if it continues to spread through the region.

King penguins are the worlds second-largest penguin, at about 3ft tall, and can live for more than 20 years in the wild. The suspected case was recorded on South Georgia island in the Antarctic region, according to the latest update from the Scientific Committee on Antarctic Research (Scar). A gentoo penguin was also suspected to have died from H5N1 at the same location.

Quick Guide

What is H5N1, the deadly strain of bird flu sweeping the world?

The current outbreak of bird flu started in Europe in 2021. By September 2022, H5N1 had been recorded in63 wild bird species across 37 countries, according to anavian influenza overviewpublished by the European Food Safety Authority. It hits seabirds particularly hard because they sit so close together during the breeding season: some colonies experience losses of 50% to 60%.

Then it crossed the Atlantic, with thefirst US caserecorded in an American wigeon duck found in South Carolina in January 2022. By November it had reachedSouth America. More than 40% of all Peruvian pelicans died over a period of a few weeks in early 2023.

Working out how many wild birds have died is difficult because so many carcasses are never found or counted. Researchers say it may bein the millions.

Does it affect other species?

The H5N1 virus has multiple genes that can switch and evolve together to spread the virus quickly into a wide range of species. The death of anestimated 20,000 sea lionsin Chile and Peru shows that this is a disease that also kills mammals en masse. Black bears, brown bears and polar bears have also been killed.

How did it reach the Antarctic, and what will happen next?

The spread of this disease is facilitated by the migration routes of wild birds. It took justthree monthsto spread almost 4,000 miles down South America, and it was seen as inevitable it would at some point reach the Antarctic.

It was first reported in the region in October 2023 among brown skua on Bird Island, off South Georgia. Since then it has spread into elephant seals, fur seals and kelp gulls. Most recently, it has been recorded in Antarcticpenguin populationstoo.

So far there are no recorded cases on the Antarctic mainland, although researchers expect that to happen in the coming months. This latest H5N1 virus is yet to be reported in Oceania.

Separately, at least one gentoo penguin has been confirmed to have died from H5N1 on the Falkland Islands 900 miles (1,500km) west of South Georgia with more than 20 chicks either dead or also showing symptoms. Since H5N1 arrived in the Antarctic, there have been mass deaths of elephant seals as well as increased deaths of fur seals, kelp gulls and brown skua in the region.

Previous outbreaks in South Africa, Chile and Argentina show penguins are susceptible to the disease. Since it arrived in South America, more than 500,000 seabirds have died of it, with penguins, pelicans and boobies among those most heavily affected.

Ed Hutchinson, a molecular virologist at the MRC-University of Glasgow Centre for Virus Research, said: The arrival of this H5N1 virus in the Antarctic towards the end of last year rang alarm bells because of the risk it posed to wildlife in this fragile ecosystem. And while it is very sad to hear reports of penguins dying it is unfortunately not at all surprising.

Diana Bell, emeritus professor of conservation biology at the University of East Anglia, said she had feared something like this would happen. Im just devastated, really as will everybody who cares about penguins and the Antarctic Given their colonial social organisation, youd just wonder how quickly it would go through the colonies.

So far, there are no recorded cases on the Antarctic mainland, according to Scar mapping data, but this could be because there are so few people present to record possible fatalities. Avian flu adds to the pressures already faced in these pristine polar ecosystems a study in 2018 warned that the climate crisis and overfishing meant Antarcticas king penguins could disappear by the end of the century.

The disease is also ripping through wildlife populations in the Arctic. In December, it was confirmed that for the first time a polar bear had died of H5N1. As with penguins, it is possible that more bears have died unnoticed as they tend to live in remote places with few people.

First penguins die in Antarctic of deadly H5N1 bird flu strain - The Guardian

In what comes as a first, at least one king penguin is suspected to have died from bird flu in the Antarctic. If the suspicion is confirmed, it could spell havoc for the population of penguins on the continent.

COMMERCIAL BREAK

SCROLL TO CONTINUE READING

According to the Scientific Committee on Antarctic Research (Scar), the case was recorded on South Georgia Island. A gentoo penguin is also believed to have died after contracting the H5N1 virus at the same location. More than 20 chicks were also either dead or showed symptoms of the virus.

Currently, the king penguins have clustered together for the breeding season. If the lethal variant of avian flu is indeed found in the dead penguin, it could rip through entire colonies and continue to spread through the region.

King penguins measure about 3 feet in heightand are regarded as the world's second-largest penguins behind Emperor penguins.

Earlier this month, using satellite imagery, researchersrevealedpreviously unknown colonies of emperor penguins along the edges of Antarctica.The scientists said that the finding of these nests adds a few thousand extra penguins to the earlier estimated population of 550,000.

However, if the bird flu reaches them, it could be disastrous and wipe out the entire species. Emperor penguins are already considered "near threatened" and face extinction. The new bird flu scare has added to the challenge to protect them.

Watch:Four new emperor penguin groups discovered in Antarctica

The highly contagious H5N1 virus was first reported when it made its way to populations of brown skuas on Bird Island, part of the British overseas territory of South Georgia and the South Sandwich Islands, in October last year.

The death of themigrating brown skuas led researchers to send swabs back to the UK for testing. The results confirmed the presence of H5N1 on the Antarctic island.

Scientists are concerned that owing to the continent's prior lack of exposure to H5N1, the wildlife has no natural immunity towards the virus. The USCenters for Disease Control and Prevention states that there have been instances where bird flu has been contracted by the mammals who eatpresumably infected birds or poultry.

Through this way, the virus might be able to jump from birds to mammals, therefore having a tremendous impact on the region's ecosystem.

PHOENIX As flu season reaches its peak, Maricopa County hospital emergency rooms and urgent care clinics are filling up with people with flu and flu-like illnesses. Health professionals advise residents to take care of themselves and their community members with preventive measures.

Mercedes Morris, a nurse practitioner at Banner Urgent Care, has worked in various facilities throughout the Valley for two years. She feels this year has brought a higher volume of influenza cases than in previous years.

Influenza can affect all age groups and the seasons are from October through May, Morris said. Right now, were basically at the peak.

The Arizona Department of Health Services reported 30,969 cases of influenza in the state since the beginning of the season on Oct. 1 through Wednesday. Both flu and RSV respiratory syncytial virus peaked during the holiday season and health providers report seeing an influx of respiratory illness cases ever since then.

Aeyrie Reiff, a family nurse practitioner, has been working with the Banner Urgent Care unit since 2008.

Its been busy. I think a lot of that could just be contributed to people interacting with other people again, right? Reiff said. We just had Christmas and New Years holidays and people were once again allowed or willing to be involved with their families and friends. Anytime you have that intersection, youre going to have illness.

This marks a major change from the pandemic, when urgent care facilities were handling high numbers of cases of both influenza and COVID-19, overwhelmed by the number of patients with severe symptoms.

After going through the pandemic, everything feels simpler, Reiff said. The stress, the lack of supplies, the lack of everything that we had during that time really puts into perspective how good we have it.

According to the Centers for Disease Control and Prevention, professional health care is recommended for those experiencing emergency warning signs of the flu.

Emergency warning signs include: difficulty breathing, persistent chest pain, seizures, lack of urination, severe muscle pain, fever or cough that improve but then return or worsen, and worsening of chronic medical conditions.

Those at higher risk including people 65 years or older, people with chronic medical conditions, pregnant women and young children should also pay attention to flu symptoms and visit a health care professional, according to the Maricopa County Public Health Department.

So with anything, I think numbers are relative, for all this stuff, Reiff said. What matters more is how well youre caring for yourself.

If you already have a weak kidney or weak lungs or a weak heart, your risk of having a severe case is going to be higher, Reiff said. Same thing with COVID or any of these respiratory illnesses.

Those with high-risk lifestyles, such as essential workers, should evaluate their symptoms before returning to work.

If youre a person that is constantly in front of the public, if youre a person thats constantly doing things around many people, your risk for getting a communicable disease can be much higher as opposed to someone that does a stay-at-home job, Reiff said.

Medical professionals say vaccines are essential in protecting yourself and others. Both nurse practitioners said vaccines will be effective throughout the remainder of this years flu season; they advised getting them even now.

Vaccines are important, they help decrease risk. I think thats what a lot of this comes down to when you think about preventative treatment, Reiff said. You need to think about yourself and how much risk youre putting yourself in.

If youre having any kind of symptoms, fevers, body aches, chills: stay indoors, Morris said. Avoid large crowds, wear a mask, good hand hygiene, push lots of fluids.

NEW ORLEANS (WGNO) As winter sets in, the increased prevalence of colds, flu, COVID-19, RSV and other illnesses becomes a familiar concern.

Many wonder why these illnesses seem to flourish during the colder months. The answer lies in the intricate interplay between temperature, humidity and the behavior of viruses.

Cold weather alone does not cause illnesses, but it does create conditions that favor the spread of viruses.

The National Institutes of Health notes that low temperatures can weaken the immune response in the nasal passages, making individuals more susceptible to viral infections. Additionally, people tend to spend more time indoors during the winter, increasing the likelihood of close contact and transmission.

Viruses, including the flu and SARS-CoV-2 (the virus responsible for COVID-19), are known to travel through respiratory droplets expelled from the body when an infected person talks, coughs or sneezes. In colder temperatures, these droplets can travel farther and remain in the air longer.

The cold air tends to be drier, causing respiratory droplets to evaporate more slowly. This means that virus-containing droplets can linger in the air for extended periods, increasing the risk of exposure for individuals in the vicinity.

Research from the NIH indicates that certain respiratory viruses, like the flu virus, may survive better in cold and dry conditions.

Cold temperatures can help the viruss outer membrane become more stable, allowing it to persist on surfaces for longer periods. This extended viability on surfaces contributes to the ease of transmission through contact with contaminated surfaces.

Humidity levels also play a crucial role in the transmission of respiratory illnesses. According to the CDC, low humidity in winter can dry out the mucous membranes in the respiratory tract, reducing the bodys natural defenses against viruses. Low humidity may also make respiratory droplets smaller, enabling them to stay airborne for longer periods.

The winter months create an environment conducive to the spread of many viral illnesses. Cold temperatures, low humidity and the tendency to spend more time indoors all contribute to the increased transmission of viruses.

Understanding these factors can empower individuals to take appropriate precautions, such as frequent hand washing, wearing masks and practicing social distancing, to lower the risk of getting sick during the winter season.

Cold and Contagious: How winter weather helps viruses live longer, travel farther - WGNO New Orleans

With Canadas colder weather comes respiratory virus season, with flus and RSV circulating alongside the COVID-19 virus, which remains with us. While Canadians learned a lot about how to protect themselves from illness over the course of the pandemic, new information released by health care practitioners can help inform decisions, from the availability of flu shots to any changes in COVID protocols.

Well be publishing an update on respiratory virus season each week. Looking for more information on the topic you dont see here? E-mail audience@globeandmail.com to see if we can help you.

According to new public health agency data, flu season may be on the way out.Kosamtu/iStockPhoto / Getty Images

Public health officials across the country say its not too late to get vaccinated against influenza. Find out about clinics and availability for each province and territory here:

Newfoundland; Prince Edward Island; Nova Scotia; New Brunswick; Quebec; Ontario; Manitoba; Saskatchewan; Alberta; British Columbia; Yukon; Northwest Territories; Nunavut

All of the indicators PHAC uses to track the flu are at or below expected levels for this point in the season, according to the latest FluWatch report.

In the week ended Jan. 20, provinces reported 82 flu-related hospital admissions, 10 ICU admissions and fewer than five deaths linked to the flu. Influenza A continues to dominate, with 96 per cent of flu-related hospital admissions caused by the H1N1 subtype. Seniors and children under the age of five have the highest cumulative hospitalization rates over the course of the season.

The three authorized vaccines, manufactured by Pfizer-BioNTech, Moderna and Novavax, protect against the XBB.1.5 subvariant of COVID-19 and should provide good protection against related families, including the JN.1 subvariant, which now accounts for about two-thirds of cases in Canada. The reformulated mRNA shots from Pfizer-BioNTech and Moderna are approved for anyone six months and older. Novavaxs shot is approved for those 12 and older.

COVID-19 vaccine information for the provinces and territories can be found here:

Newfoundland; Prince Edward Island; Nova Scotia; New Brunswick; Quebec; Ontario; Manitoba; Saskatchewan; Alberta; British Columbia; Yukon; Northwest Territories; Nunavut

Although the situation varies from province to province, COVID-19 activity levels are stable or decreasing in most of Canada. Nationally, the share of lab tests coming back positive has decreased over the past month. The number of hospital beds occupied by patients with COVID dropped slightly in the week ended Jan. 23, to 3,939 from 4,062 the week before. The number of patients with COVID in ICUs was nearly unchanged.

Symptoms of COVID-19 can vary but generally include sore throat, runny nose, sneezing, new or worsening cough, shortness of breath or difficulty breathing, feeling feverish, chills, fatigue or weakness, muscle or body aches, new loss of smell or taste, headache, abdominal pain and diarrhea. According to Health Canada, you may start experiencing symptoms anywhere from one to 14 days after exposure. Typically, symptoms appear three to seven days after exposure.

Health Canada advises following the testing guidelines provided by your local public health authority if you have symptoms or have been exposed to a person with COVID-19. If you test positive, immediately isolate yourself from others, including those in your household, and follow the advice of your local public health authority on isolation requirements.

Respiratory viruses are spread from person to person or through contact with contaminated surfaces, so its important to protect against both forms of transmission. Health Canada recommends wearing a medical mask or respirator, washing your hands regularly or using hand sanitizer, covering your coughs and sneezes and cleaning and disinfecting high-touch surfaces and objects. If you feel sick, stay home and limit contact with others.

What to know about respiratory viruses in Canada this week - The Globe and Mail

A bird flu outbreak is ravaging Californias massive poultry industry, forcing businesses to kill more than one million chickens and causing egg prices to soar.

Mike Weber, who owns Sunrise Farms in Sonoma County, learned last month that his chickens had become infected with the highly-contagious virus. Per government rules, he had to slaughter his entire flock of 550,000 egg-laying hens.

Its a trauma. Were all going through grief as a result of it, Weber told the Associated Press inside an empty hen house. Petaluma is known as the Egg Basket of the World. Its devastating to see that egg basket go up in flames.

The avian flu is wreaking havoc in California a year after the disease caused egg prices to skyrocket to record highs nationwide due to a shortage following an outbreak in the Midwest.

Officials have declared a state of emergency in Sonoma County, north of San Francisco, after nearly a dozen commercial farms have killed more than a million birds to curb the outbreak in the last two months, devastating farmers, workers and their customers.

Merced County in Central California also has been hit hard, with outbreaks reported recently at several large commercial egg-producing farms.

Bird flu is spread by ducks, geese and other migratory birds. While the waterfowl can carry the virus without getting sick, they easily spread the disease to poultry birds through their droppings and nasal discharges, according to experts.

State Veterinarian Annette Jones urged farmers to keep their flocks indoors until June including organic chickens that are required to have outdoor access.

We still have migration going for another couple of months. So weve got to be as vigilant as possible to protect our birds, said Bill Mattos, president of the California Poultry Federation.

The outbreak caused egg prices in the Bay Area to spike over the holidays before eggs could be imported from other parts of the country.

This latest outbreak of the virus began in early 2022 and has prompted officials to slaughter nearly 82 million birds, mostly egg-laying chickens, in 47 U.S. states, according to the U.S. Department of Agriculture. It has spread to every habited continent except for Australia, experts said.

The price of a dozen eggs more than doubled to $4.82 at its peak in January 2023. It returned to normal as farmers re-stocked their flocks. Turkey and chicken prices also increased.

The outbreak has affected more than 7 million chickens in about 40 commercial flocks and 24 backyard flocks in California, according to the USDA. Most occurred over the past two months on the states North Coast and Central Valley regions.

Ettamarie Peterson maintains 50 chickens that produce eggs she sells from her backyard barn for 50 cents each.

Im very concerned because this avian flu is transmitted by wild birds, and theres no way I can stop the wild birds from coming through and leaving the disease behind, Peterson said.

Despite putting in place strict biosecurity measures to protect his chickens, Webers flock at Sunrise Farms became infected before Christmas.

The virus got to the birds so bad and so quickly you walked in and the birds were just dead, Weber said. Heartbreaking doesnt describe how you feel when you walk in and perfectly healthy young birds have been just laid out.

He said he and his employees have spent the last month cleaning and disinfecting the hen houses.

Bird flu wreaking havoc in California's 'Egg Basket' region - New York Post

A year after the bird flu led to record egg prices and widespread shortages, the disease known as highly pathogenic avian influenza is wreaking havoc in the U.S. state of California, which escaped the earlier wave of outbreaks that devastated poultry farms in the Midwest.

The highly contagious virus has ravaged Sonoma County, where officials have declared a state of emergency.

Following government rules, Mike Weber's company, Sunrise Farms, had to slaughter its entire flock of egg-laying hens 550,000 birds to prevent the disease from infecting other farms in Sonoma County north of San Francisco.

During the past two months, nearly a dozen commercial farms have had to destroy more than 1 million birds to control the outbreak, dealing an economic blow to farmers, workers and their customers.

Merced County in Central California also has been hit hard, with outbreaks at several large commercial egg-producing farms in recent weeks.

Experts say bird flu is spread by ducks, geese and other migratory birds. The waterfowl can carry the virus without getting sick and easily spread it through their droppings to chicken and turkey farms and backyard flocks through droppings and nasal discharges.

California poultry farms are implementing strict biosecurity measures to curb the spread of the disease. State Veterinarian Annette Jones urged farmers to keep their flocks indoors until June, including organic chickens that are required to have outdoor access.

The loss of local hens led to a spike in egg prices in the San Francisco Bay Area over the holidays before supermarkets and restaurants found suppliers from outside the region.

While bird flu has been around for decades, the current outbreak of the virus that began in early 2022 has prompted officials to slaughter nearly 82 million birds, mostly egg-laying chickens, in 47 U.S. states, according to the U.S. Department of Agriculture. Whenever the disease is found the entire flock is slaughtered to help limit the spread of the virus.

The price of a dozen eggs more than doubled to $4.82 at its peak in January 2023. Egg prices returned to their normal range as egg producers built up their flocks and outbreaks were controlled. Turkey and chicken prices also spiked, partly due to the virus.

Climate change is increasing the risk of outbreaks as changing weather patterns disrupt the migratory patterns of wild birds, said Maurice Pitesky, a poultry expert at the University of California, Davis. For example, exceptional rainfall last year created new waterfowl habitat throughout California, including areas close to poultry farms.

"We have wild birds that are full of virus. And if you expose your birds to these wild birds, they might get infected and ill," said Rodrigo Gallardo, a UC Davis researcher who studies avian influenza.

Gallardo advises the owners of backyard chickens to wear clean clothes and shoes to protect their flocks from getting infected. If an unusual number of chickens die, they should be tested for avian flu.

Ettamarie Peterson, a retired teacher in Petaluma, has a flock of about 50 chickens that produce eggs she sells from her backyard barn for 50 cents each.

"I'm very concerned because this avian flu is transmitted by wild birds, and there's no way I can stop the wild birds from coming through and leaving the disease behind," Peterson said. "If your flock has any cases of it, you have to destroy the whole flock."
