DATE: March 6, 2018

LOCATION: Jasper County, Jasper, Missouri, U.S.A.

DETAILS: As part of routine, pre-slaughter testing and surveillance for H5/H7 Avian Influenza, H7N1 presumptive low pathogenic avian influenza (LPAI) was detected in a healthy commercial meat turkey flock based upon H7 PCR and antibody to H7 and N1; further characterization is pending virus recovery.


There have been no clinical signs of illness or increased mortality on the premises. This is the first detection of H7 LPAI in commercial poultry in the U.S. for 2018. The turkeys will be depopulated through controlled marketing. The USDA Animal Plant Health Inspection Service (APHIS) and the Missouri Department of Agriculture are conducting a comprehensive epidemiological investigation and have implemented enhanced surveillance and testing related to this finding. A total of two additional commercial poultry premises located within the 10 km [approx. 6.2 mi] zone were tested negative for influenza virus.
