Update on HPAI from the Government of Canada: In addition to the robust protective measures that already exist, the Government of Canada, in collaboration with stakeholders, is expanding its surveillance to manage the possible emergence of HPAI in Canada by: requiring negative HPAI test results for lactating dairy cattle being imported from the United States to Canada. conducting enhanced testing of milk at the retail level to look for viral fragments of HPAI. facilitating the voluntary testing of cows that are not presenting with clinical signs of HPAI to facilitate enhanced industry biosecurity efforts.

FSIS collected 30 samples of ground beef from retail outlets in the states with dairy cattle herds that had tested positive for the H5N1 influenza virus at the time of sample collection. The samples were sent to APHIS’ National Veterinary Services Laboratories (NVSL) for PCR testing. On May 1, NVSL reported that all samples tested negative for H5N1. These results reaffirm that the meat supply is safe." LINK
1st May 2024: Update on FDA testing of U.S. retail milk: "The FDA is announcing an additional set of results from our national commercial milk sampling study underway in coordination with USDA. The study includes 297 total retail dairy samples. New preliminary results of egg inoculation tests on a second set of 201 quantitative polymerase chain reaction (qPCR)-positive retail dairy samples, including cottage cheese and sour cream, in addition to fluid milk, show that pasteurization is effective in inactivating HPAI. This additional preliminary testing did not detect any live, infectious virus." LINK
