It has been more than a month since the last case of avian influenza was detected in the US, but USDA Secretary Tom Vilsack is not ready to declare the outbreak over, according to a recent interview with the Associated Press.
Vilsack told the news agency that poultry producers have benefitted from the warm weather this summer since these high temperatures can kill the virus. However USDA officials feel the outbreak could return the Midwest in the fall and spread to other regions as well.
