U.S. mandates bird flu testing for milk supply amid outbreak
Global News
Bird flu has infected more than 500 dairy herds in top milk state California, and more than 700 nationwide since March, raising concerns of the impact to the milk supply.
The U.S. issued a federal order on Friday mandating that the national milk supply be tested for bird flu, Agriculture Secretary Tom Vilsack told Reuters, as authorities seek to grapple with the rapid spread of the virus among dairy herds.
Bird flu has infected more than 500 dairy herds in top milk state California, and more than 700 nationwide since March, according to the U.S. Department of Agriculture, raising concerns of the impact to farmers and the milk supply as well as the risk to human health from ongoing spread.
Nearly 60 people have contracted the virus since April, most of them workers on infected poultry and dairy farms, according to the U.S. Centers for Disease Control and Prevention. The symptoms have been mild and CDC officials have said the risk to the general public from bird flu is low.
The USDA first announced it would begin national milk testing in October after a push from industry and veterinary groups for stronger surveillance of the virus, but had not detailed the extent of the program or how it would be implemented.
The testing plan, which will involve monthly or weekly sample collection from bulk milk tanks and dairy processors, will be rolled out first in California, Colorado, Michigan, Mississippi, Pennsylvania, and Oregon, Vilsack said.
The latter three states have not reported bird flu infections in dairy cattle.
“It gives us the opportunity to get potentially a heads up about potentially new virus in areas of a state that currently has the virus, or new states,” Vilsack said of the testing.
The agency will begin the testing on Dec. 16, Vilsack said.
