Another brand of raw pet food has been found to contain bird flu and has made at least five house cats presumably sick with the virus, health officials say.
The FDA announced Monday it has begun collecting samples of aged raw cow's milk cheese to test for bird flu as the U.S. battles an outbreak of the virus.
The call to authorize a vaccine comes after the CDC announced that a person in Louisiana was hospitalized with the country's first known case of severe illness caused by the virus earlier this month.
