food<\/u><\/a> supply, and milk from the sick animals is being diverted or destroyed. Pasteurization also kills viruses and other bacteria, and the process is required for milk sold through interstate commerce, the agency said.<\/p>\n\n\n\n\u201cAt this stage, there is no concern about the safety of the commercial milk supply or that this circumstance poses a risk to consumer health,\u201d the USDA said in a statement.<\/p>\n\n\n\n
The federal government said its tests in the cattle did not detect any changes to the virus that would make it spread more easily to people.<\/p>\n\n\n\n
Dairy farmers in Texas first became concerned three weeks ago when cattle started falling ill with what officials called \u201cmystery dairy cow disease,” Texas Department of Agriculture Commissioner Sid Miller said. Milk production fell sharply and the cows were lethargic and weren’t eating much.<\/p>\n\n\n\n
\u201cWe hadn’t seen anything like it before,\u201d he said. \u201cIt was kind of like they had a cold.\u201d<\/p>\n\n\n\n
The state’s animal health commission began an investigation that included tests for bird flu, spokeswoman Erin Robinson said. Based on findings from Texas, USDA officials think the cows got the virus from infected wild birds.<\/p>\n\n\n\n
Experts say livestock appear to recover on their own within seven to 10 days. That’s different than bird flu outbreaks in poultry, which necessitate killing flocks to get rid of the virus. Since 2022, outbreaks in have led to the loss of about 80 million birds in U.S. commercial flocks.<\/p>\n\n\n\n
So far, the virus appears to be infecting about 10% of lactating dairy cows in the affected herds, said Michael Payne, a food animal veterinarian and and biosecurity expert with the University of California-Davis Western Institute for Food Safety and Security.<\/p>\n\n\n\n
\u201cThis doesn\u2019t look anything like the high-path influenza in bird flocks,\u201d he said.<\/p>\n\n\n\n
Bird flu was detected in unpasteurized, clinical samples of milk from sick cattle collected from two dairy farms in Kansas and one in Texas. The virus was also found in a nose and throat swab from another dairy in Texas.<\/p>\n\n\n\n
Officials called it a rapidly evolving situation. The Food and Drug Administration and Centers for Disease Control and Prevention are involved, along with officials in the three states. Another dairy-heavy state, Iowa, said it is monitoring the situation.<\/p>\n\n\n\n
Dairy industry officials said that producers have started enhanced biosecurity efforts on U.S. farms, including limiting the amount of traffic into and out of properties and restricting visits to employees and essential personnel.<\/p>\n\n\n\n
Bird flu previously has been reported in 48 different mammal species, Payne noted, adding: \u201cIt was probably only a matter of time before avian influenza made its way to ruminants.\u201d<\/p>\n\n\n\n
