H5N1 virus particles found in meat from dairy cow

Meat from a dairy cow sent to slaughter contained particles of the H5N1 avian influenza virus — the first such finding since the virus jumped to cattle from birds a few months ago, said the Agriculture Department. The USDA also confirmed infections in five additional herds — three in South Dakota and two in Colorado — raising the U.S. total to 63 herds in nine states.

H5N1 virus was undetected for months in dairy cattle, researchers say

Genetic testing indicates the H5N1 bird flu virus jumped from wild birds to dairy cattle in Texas approximately four months before it was identified in late March, said a nationwide team of researchers. “Continued transmission of H5N1 HPAI [highly pathogenic avian influenza] within dairy cattle increases the risk for infection and subsequent spread of the virus to human populations.”

Bird flu virus likely travels from cow to cow via milk, says USDA

The “primary vector” for transmitting the H5N1 bird flu virus from dairy cow to dairy cow seems to be milk from an infected animal, said the USDA’s chief veterinary officer on Wednesday. Dr. Rosemary Sifford also said the USDA was considering whether to offer compensation to dairy farmers for cooperating in the investigation of the disease and for adopting stronger biosecurity safeguards.

Bird flu found in dairy herds in five states

Bird flu, which killed more than 82 million birds in U.S. domestic flocks in the past two years, has appeared in dairy herds in Idaho, Kansas, Michigan, New Mexico, and Texas, said federal officials. The outbreaks, affecting a relatively small number of cattle, are not expected to affect milk supply or prices at the grocery store.

USDA: Stronger biosecurity reduced spread of bird flu

Fewer than 900,000 birds in domestic flocks have died due to highly pathogenic avian influenza (HPAI) this year, said the Agriculture Department in a review of bird flu outbreaks that date from February 2022.

Worrisome signs of mammal-to-mammal spread of bird flu

The ongoing bird flu outbreak is the largest ever in Europe and North America, and recent reports suggest the disease has passed from mammal to mammal, raising the risk of a spillover into humans, said a U.S. medical journal. The director general of the World Health Organization said that while the risk to people remained low, the reported infections in mink, otters, and sea lions “must be monitored closely.”

Bird flu the cause of high egg prices, says USDA

Egg prices at the grocery store were elevated throughout 2022 due to outbreaks of highly pathogenic avian influenza (HPAI) among egg-laying hens, said USDA economists. “Lower-than-usual shell egg inventories near the end of the year, combined with increased demand stemming from the holiday baking season, resulted in several successive weeks of record-high egg prices."

Bird flu losses break record

A record 50.54 million birds in domestic flocks have died of highly pathogenic avian influenza (HPAI), or were culled to prevent spread of the viral disease since February, according to USDA data.

‘No fowl play’ as Biden pardons Thanksgiving turkeys

In a traditional moment of White House whimsy ahead of Thanksgiving, President Biden pardoned tom turkeys "Chocolate" and "Chip" on Monday. An outbreak of bird flu has driven up turkey prices and crimped supplies for the holiday season.

Bird flu losses now on par with worst U.S. animal disease event

In nine months, nationwide outbreaks of highly pathogenic avian influenza have killed 50.12 million birds in domestic flocks, said USDA data on Wednesday. Losses from HPAI and the culling of infected flocks are now on par with the 2014-15 bird flu outbreak, which the USDA has described as the most significant animal disease event in U.S. history.

Bird flu losses near U.S. record with outbreak on Iowa egg farm

The Agriculture Department has spent $450 million to combat this year’s outbreak of bird flu, but losses among domestic flocks are nearing the record set seven years ago in the largest-ever U.S. animal health emergency. The outbreak has driven up egg prices and tightened the supply of holiday turkeys.

As bird flu losses mount, USDA advises ‘plan for elevated risk’

For the first time, researchers have tracked the movements of a wild duck infected with bird flu, information that could help them come up with disease mitigation strategies against the viral disease, said the U.S. Geological Survey on Wednesday. More than 47.7 million birds in U.S. domestic flocks have died in outbreaks of highly pathogenic avian influenza since February.

More than 47 million birds lost to avian influenza

Bird flu was discovered in a backyard flock in the Albuquerque area, making New Mexico the 42nd state where the viral disease has been confirmed this year, said the Agriculture Department on Thursday.

Bird flu found in 40th state this year

Scientists confirmed a backyard flock of poultry in northwestern Tennessee was infected with highly pathogenic avian influenza (HPAI), part of a resurgence of the disease in the central states. Some 3.37 million birds in domestic flocks have died of bird flu so far this month; nationwide losses during September will be the largest since April.

Ohio is hit hardest as bird flu returns to the Midwest

After a summertime lull, bird flu is back in the Midwest, the heart of U.S. egg and turkey production, with outbreaks at commercial poultry farms in Minnesota and Ohio since Sept. 1. Some 43.85 million birds have been culled this year due to highly pathogenic avian influenza, and one analyst says turkey and egg prices may remain elevated for some time to come.

Poultry exports face potential risks from avian influenza

The risk of another outbreak of avian influenza this fall remains elevated and the stakes for poultry producers couldn’t be higher, with U.S. poultry exports expected to reach record levels in 2022, said a report Tuesday from CoBank's Knowledge Exchange.

As bird flu outbreaks slow, USDA urges readiness for autumn

While this year’s outbreaks of bird flu, the worst in seven years, are following the usual pattern of dissipating during hot weather, it’s too early to declare the threat over, said the Agriculture Department on Wednesday.

‘Large supply gaps’ coming, says No. 2 U.S. turkey processor

Bird flu will have a “meaningful impact” on turkey supplies in coming months, said the head of Hormel Foods, the second-largest turkey processor in the country, on Thursday. Chief executive Jim Snee said Hormel anticipated “large supply gaps” for its Jennie-O Turkey Store operations in the months ahead because of flock losses.

USDA raises food inflation forecast for fourth month in a row

Bird flu outbreaks are driving up egg and poultry meat prices far faster than usual, with eggs expected to cost 20 percent more and poultry 9 percent more this year than their 2021 averages, said the Agriculture Department on Wednesday.
