University of California poultry experts are urging poultry owners to examine biosecurity for their flocks after avian influenza was confirmed in commercial chickens in Tennessee by the USDA Animal and Plant Health Inspection Service on Sunday (March 5). To protect the birds’ health, UC scientists recommend taking measures to prevent poultry from coming into contact with wild birds.
“Based on the initial sequence of the virus, the source of the virus is thought to be waterfowl, said Maurice Pitesky, UC Cooperative Extension poultry specialist in the School of Veterinary Medicine at UC Davis. “This is consistent with the current understanding of how avian influenza spreads and evolves. Specifically, juveniles are infected at breeding locations and travel south in the fall carrying virus. As the waterfowl move southward, they are more likely to interact with other species, increasing the risk of interspecies transmission and formation of new varieties of avian influenza.” Read more
