Dairy herd in Minnesota quarantined due to H5N1 bird flu detection in milk; public milk supply remains safe.

A dairy herd in Stearns County, Minnesota, has been quarantined after H5N1 bird flu was detected in its milk. The herd will remain in quarantine until tests show the cows are no longer infected. The Minnesota Board of Animal Health conducts monthly tests on raw milk from dairy farms due to the spread of avian flu among birds. The public milk supply remains safe as milk sold in stores is pasteurized, which kills any viruses.
