The U.S. avian flu outbreak of
2017 reinforced the need for
site-specific biosecurity plans
for poultry farms with approved
emergency response plans.
No poultry farm is immune to an avian influenza outbreak;
therefore, having a plan to deal with such a situation is crucial, explained Dr. Charles Hatcher, state veterinarian with
the Tennessee Department of Agriculture at the 2017 Live
Production and Welfare Seminar in Nashville, Tennessee.
"You can never do too much planning," Hatcher said.
A lapse in biosecurity practices is the most likely
way for viruses to enter the house. Each premise must
have its own site-specific plan and conduct internal audits of facilities and their practices regularly. The state
of Tennessee will be requiring producers to have a
National Poultry Improvement Plan (NPIP) compliant
biosecurity plan by the end of October 2017.

of H7N9 avian influenza was announced on March
5, and it affected a broiler breeder flock in Lincoln
County. A flock of chickens at a commercial broiler
breeder operation in Giles County, Tennessee, tested
positive for low pathogenic H7N9 avian influenza. The
state's second avian influenza case in 2017 was confirmed on March 8.
On March 14, the Alabama Department of
Agriculture and Industries (ADAI) issued a stop movement order for certain poultry in the state, after three
potential cases of avian influenza were identified.
It halted movement of birds to poultry shows, swap
meets, flea markets and poultry auctions.
The possible infections occurred in three north
Alabama counties that border Tennessee, where the
two cases of avian influenza were previously confirmed. These cases were a backyard flock of layers, a
commercial broiler breeder flock and a backyard flock
of guinea fowl, which were confirmed as positive for
low pathogenic avian flu on March 10, 14 and 15, respectively.
In Alabama on March 16 and 17, cases of a low
pathogenic strain of the disease were confirmed in
a commercial poultry breeding operation in Pickens
County and a backyard flock in Madison County. Both
detections were not related to highly pathogenic avian
