Update on avian influenza in in Alabama

16 March, 2017

Results have been received from the USDA National Veterinary Services Laboratory (NVSL) in Ames, Iowa on the sample collected from a guinea fowl at the TaCo-Bet Trade Day flea market in Scottsboro, located in Jackson County, Alabama. The sample tested positive for low pathogenic H7N9 avian influenza (LPAI). The premises of origin for the guinea fowl, also located in Jackson County, Ala., is under quarantine and continued surveillance. The guinea fowl in question have been depopulated. 
Testing is still ongoing of samples submitted to NVSL from the other two premises in north Alabama, the commercial breeder flock in Lauderdale County and the backyard flock in Madison County. Out of an abundance of caution, the company decided to depopulate the entire flock at the commercial breeder operation in Lauderdale County and the birds were properly buried on the farm. The depopulation was not required but a decision made by the poultry company. The entire backyard flock in Madison County was also depopulated at the owners request. According to USDA, both cases are considered presumptive low pathogenic (LPAI) avian influenza because neither flock showed signs of illness. Today, USDA Animal and Plant Health Inspection Service (APHIS) and the Tennessee Department of Agriculture (TDA) confirmed a second case of highly pathogenic H7N9 avian influenza in a commercial breeder flock in Lincoln County, Tennessee. This H7N9 strain is of North American wild bird lineage and is the same strain of avian influenza that was previously confirmed in Tennessee. 
Poultry and egg production generate more than $15 billion a year in Alabama, and more than 85,000 jobs statewide are tied to the poultry and egg business.
