U.S. tally of bird flu infections in people rises to 44
Three additional dairy farmworkers in California contracted bird flu, raising the state total to 20 cases and the U.S. tally to 44 people since March, said the Centers for Disease Control on Monday. "To date, person-to-person spread of H5 bird flu has not been identified in the United States" and the risk to the general public remained low, said the agency.
California dairy worker has bird flu, first in the state
A dairy farm worker in California’s Central Valley with mild symptoms tested positive for the bird flu virus — the first case in the state and the 16th in the nation this year — said the California Department of Public Health on Thursday. The worker was being treated with antiviral medication and was staying home to recover.
California quarantines three dairy farms hit by bird flu outbreaks
The H5N1 avian flu virus infected three dairy herds in California's Central Valley, the first time the disease has been confirmed in the nation's largest milk-producing state, said officials. California was the first new state to be hit by the disease since Oklahoma reported cases on July 11.
Risk assessment validates ongoing U.S. response to H5N1 virus, says CDC
While the risk to the general population from the H5N1 avian flu virus remains low, an assessment rated its future pandemic potential as moderate, the same as previous assessments, said the Centers for Disease Control and Prevention. "The results of this IRAT [Influenza Risk Assessment Tool] validate the pro-active, coordinated U.S. government response," said the CDC in a weekly report on bird flu.
Colorado workers are first since 2022 to catch bird flu from poultry
A total of five workers — two more than initially reported — contracted mild cases of bird flu while culling infected chickens with the viral disease on an egg farm, said Colorado public health officials. They were the first poultry workers known to have contracted bird flu since May 2022; four dairy farmworkers have been diagnosed with the disease, which is also spread by cows, since April, including one in Colorado.
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.
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.
Block sales of raw milk that may contain H5N1 virus, FDA asks states
To reduce the risk of bird flu infections, state health officials should bar the sale of raw milk to consumers if it contains the H5N1 avian flu virus, said the Food and Drug Administration on Thursday. Although the FDA has long warned that raw milk is a high-risk food that may carry disease-causing pathogens, more than 30 states allow the sale of unpasteurized milk from the farm, in retail stores, or through so-called cow shares.
Bird flu infects dairy herd in Iowa, 10th state to be hit
A dairy herd in northwestern Iowa is infected with the H5N1 avian flu virus, said state agriculture secretary Mike Naig on Wednesday. He called on dairy and poultry farmers to “harden their biosecurity defenses” against the virus.
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.
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.”
USDA mandates bird flu tests of dairy cows before transport
Dairy farmers will be required to test their cattle for the H5N1 bird flu virus before shipping them across state lines, announced Agriculture Secretary Tom Vilsack on Wednesday as the government tries to prevent the spread of the disease and learn more about how it is transmitted. The virus, a lethal threat to poultry, has moved from cow to cow, herd to herd, and cow to poultry, and has appeared in cows with no symptoms.
‘Traditional’ dairy states catch up with ‘modern’ ones
A generation ago, California surpassed Wisconsin, "America's Dairyland," as the No. 1 milk-producing state, a shift that exemplified the growing prominence of dairy farms in the West and Southwest with huge herds producing a flood of milk. The competition is more equally balanced now, said an analysis on Monday. Milk production is roughly equal between the "traditional" dairy states of the Midwest and Northeast and the "modern" states.
Dairy subsidies could cost $19 billion without new farm bill
The cost of price supports for dairy, and for an array of field crops, could skyrocket if Congress allows the 2018 farm law to expire without a replacement, estimated the Congressional Research Service.
House chairman says 2023 farm bill will be later than expected
Congress will have to extend temporarily the lifespan of the 2018 farm bill because it will miss the Sept. 30 deadline for enacting its successor, said House Agriculture chairman Glenn Thompson. It was the first direct acknowledgement by one of the "four corners" of farm policy — the leaders of the House and Senate Agriculture committees — that the 2023 farm bill would be late.
Can Danone reach its climate goals without scaling back dairy farming?
Last month, the French food company Danone — owner of milk and yogurt brands like Activia and Horizon Organics — pledged to cut absolute methane emissions from its milk supply chains by 30 percent by 2030, making it the first major food company with a methane-specific emissions target. But reducing those methane emissions is far from simple. A “methane ambition” document released by Danone outlines a few options, although somewhat vaguely and without acknowledging some of the controversies surrounding them. No paywall
Dairy farmers to get up to $200 million in USDA aid
The Biden administration expanded a pandemic relief program for dairy farmers on Monday to cover up to 9 million pounds of milk produced during the second half of 2020, up from the original 5 million pounds. The Agriculture Department also announced a new assistance program for organic dairy farmers, who face sharply higher feed expenses.
Sales of antibiotics for food animals rise by 6 percent — FDA
Drug makers sold 11.1 million kilograms (24.5 million pounds) of antibiotics for use in cattle, hogs and poultry last year, up 6 percent from 2021, chiefly because of a large increase in sales of antimicrobials that are not considered medically important, said the FDA on Monday. Despite year-to-year fluctuations, like last year's increase, sales are much lower nowadays than before the FDA barred the use of antimicrobials to encourage weight gain in livestock.
