USDA: Expect more cases of bird flu in dairy cattle
The H5N1 avian flu virus has been confirmed in 121 dairy herds to date and more infected herds are sure to be found as the search continues, said a USDA official on Monday as the outbreak in cattle entered its fourth month. The early summer heat wave will discourage farmworkers from wearing the full set of personal protective equipment recommended by health officials, said the dairy industry.
Few dairy farmers seek bird flu funds from USDA
Only a handful of U.S. farms — 18 in all — are accepting federal funds to quash the outbreak of the H5N1 avian flu virus among dairy herds that began three months ago, according to the Agriculture Department. <strong>(No paywall)</strong>
Little to no U.S. immunity to H5N1 avian flu virus, CDC says
Blood tests show "there is extremely low to no population immunity" among Americans to the H5N1 avian flu virus, said the Centers for Disease Control. Most of the population would be vulnerable if the virus mutated to become more readily contagious, said the CDC, but it has identified two candidate vaccines that would offer "good cross-protection" against it.
H5N1 virus was spread by cattle, people and shared equipment
After the H5N1 avian flu virus jumped from birds to dairy cattle in Texas last December, it was spread across the country by infected cows, contaminated machinery, and people who inadvertently carried the virus on their clothes and footwear from farm to farm, said USDA scientists on Thursday. Officials said the risk to the public was low because the virus has not shown signs of adapting to humans. “We should be, as we are, alert, not alarmed,” said Nirav Shah, the CDC’s principal deputy director.
Iowa asks USDA to compensate farmers for cows culled due to H5N1 virus
The federal government should compensate dairy farmers who send dairy cattle to slaughter because of the H5N1 avian flu virus, said Iowa state Agriculture Secretary Mike Naig, in announcing the second outbreak in the state. At least 90 herds in 12 states from Wyoming to North Carolina have been infected since bird flu was discovered in cattle in Texas in March.
USDA aims to isolate, exhaust H5N1 virus in dairy herds
The USDA's strategy against bird flu in dairy cattle is to identify infected herds and wait for the virus to die out within the herds, said Agriculture Secretary Tom Vilsack on Monday. "I'm confident we have a good understanding of the virus and how it is being transferred," he added.
Higher commodity prices soften farm income decline, say banks
Springtime increases in corn, soybean, and wheat prices brightened the outlook for the agricultural sector amid expectations of lower farm income this year than in 2023, said Federal Reserve regional banks in the Beige Book report on Wednesday. The Chicago and Dallas banks said the discovery of bird flu in dairy cattle was a cause for concern.
Bird flu hits large Iowa egg farm
Bird flu was confirmed at an egg farm with 4.2 million hens in Sioux County in northwestern Iowa, the first outbreak in the state this year, said agriculture officials. The Sioux County farm is one of the largest egg farms in Iowa, the No. 1 egg-producing state.
Dairy worker in Michigan has bird flu in second case of cow-to-human infection
A worker on a Michigan dairy farm contracted a mild case of H5 bird flu from infected cattle — the second cow-to-human infection since bird flu was first identified in dairy cattle in late March — said the Centers for Disease Control on Wednesday. The risk to the public remains low, said Nirav Shah, the CDC’s principal deputy director.
USDA study shows cooking kills bird flu virus in meat
In tests conducted by USDA scientists, the H5N1 bird flu virus did not survive in hamburgers cooked to internal temperatures of 145 and 160 degrees Fahrenheit, said the Agriculture Department on Thursday. “These results validate that [Food Safety and Inspection Service] recommended cooking temperatures are sufficient to kill H5N1 in meat,” it said.
USDA and HHS allot $199 million to quash bird flu threat to cattle and humans
The Biden administration poured $199 million into the fight against the H5N1 bird flu virus, which was identified in cattle for the first time seven weeks ago, a worrisome step closer to people. Agriculture Secretary Tom Vilsack said dairy farmers are eligible for up to $28,000 in USDA aid in three months to help eradicate the virus from their herds, and Health Secretary Xavier Becerra announced new funding among public health agencies to "test, treat, prevent" the virus from spreading.
CDC urges states to give PPE to farmworkers as bird flu safeguard
States should open their stockpiles of personal protective equipment for distribution to farmworkers, with top priority for dairy farms where cows are infected with the H5N1 bird flu virus, said a Centers for Disease Control official. Meanwhile, the Agriculture Department confirmed six additional cases of bird flu in cattle on Thursday, ending a 12-day pause in new cases.
‘Absolute barrier’ against spread of bird flu virus is impossible, says Califf
The agriculture and food industry is entering an era of stepped-up precautions against the spread of the H5N1 bird flu virus now that it has appeared in cattle for the first time, said FDA commissioner Robert Califf at a Senate hearing on Wednesday. “Unfortunately, there is no absolute barrier that can be created,” he said.
CDC: Texas farmworker only person known to contract bird flu from cattle
At least 200 people have been monitored for possible exposure to the H5N1 bird flu virus and 30 people have been tested, but a dairy worker in Texas is the only person known to contract the disease from cattle, said the Centers for Disease Control. "No additional human cases have been detected" since bird flu was discovered for the first time in cattle six weeks ago.
USDA is testing ground beef for bird flu virus
Agriculture Department scientists are conducting three beef safety studies following the first-ever discovery of bird flu in dairy cows a month ago, said a USDA spokesperson on Monday. The studies include tests of ground beef purchased at grocery stores in states with infected herds.
FDA: Bird flu viral fragments in milk were dead; pasteurization works
Although fragments of the H5N1 bird flu virus were found in one-fifth of milk purchased in grocery stores, a new round of high-precision testing "did not detect any live, infectious virus" and reaffirmed that the commercial milk supply is safe, said the FDA. <strong>(No paywall)</strong>
USDA assesses vaccine to protect cattle from bird flu virus
The Agriculture Department said its research agency “has begun to assess the potential to develop an effective vaccine” against the H5N1 bird flu virus in cattle, although it warned that it is too early to say how long the process would take. The virus has so far infected 29 dairy herds in eight states, though there have been no detections in commercial beef herds since the disease was identified in cattle in late March.
USDA: Test for bird flu before interstate transport of cattle
Michigan officials said the H5N1 bird flu virus has infected three additional dairy herds in the state, just as the USDA recommended farmers test their herds for the virus before moving cattle between states. The tests "should both give us more ... information and should mitigate further state-to-state spread between herds," said the USDA's animal health agency.
Second recall of raw milk in California because of bird flu
California state agriculture officials ordered the recall of raw milk from a dairy farm in the Central Valley after tests found bird flu virus in a sample from the farm's bulk tank. The state Department of Food and Agriculture warned against consumption of milk from Valley Milk Simply Bottled on the grounds that it "may lead to infection with this rare, emerging flu virus." No illnesses were reported.
