The number of new H5N1 avian influenza cases in dairy cattle appears to be tapering off.
A Thursday USDA report says the National Veterinary Services Laboratories have confirmed the presence of avian influenza in 22 dairy herds in five states during the past 30 days, but that same report shows the last confirmed case of H5N1 was more than ten days ago.
The most recent confirmation of the virus was August 13th in Colorado, where 16 herds are affected, and one Idaho herd that same day. Texas hasn’t had a new case since August first. Michigan’s last confirmed case was July 30th, and South Dakota’s last case was July 31st.
Colorado officials have been sampling all bulk tanks looking for signs of the virus.
USDA and other agencies say the food supply is safe since pasteurization kills the virus.
