remains critical in stopping the spread of
disease. "Depopulate within 24 hours of
detection; we were able to do this by foaming," said Hatcher when discussing his idea
of disease control goals.
Dr. Kate Hayes with Aviagen discussed
lessons learned from avian influenza from
her experience with the Tennessee outbreaks
at the same conference in Nashville. After
the experience with foam she implied foaming will not be their method again should
the disease become a problem for the company. She said it was challenging to clean up
in housing systems with concrete flooring.
Hatcher noted that he would consider
carbon dioxide to depopulate if need be.
The fact that broiler breeders were involved in this
outbreak is significant when considering the efficacy of
using foam for euthanasia. Foam seems to work well when
the floor is flat and the birds are all on one level, but not so
well if there are multiple levels for the birds to inhabit or
if it is below freezing out.
Hatcher said there are only two real options for disposing of the birds, onsite burial or composting.
"We did onsite burial this time but that wasn't without
issues," he said.
Hatcher would like to do composting only. Preferably in
the house or under cover, he added. The disposal method
will be preapproved by the state before the next outbreak.
When going through suggestions for producers'
individual planning processes, Hatcher suggested that
Emergency Resources Management System (ERMS)
coupled with the new Gateway is the way to go.
"Preloading premises numbers ahead of an outbreak is
a must," he said.
These numbers are used for tracking lab results. If this
isn't done it could slow down producers' whole process of
verification and depopulation as needed, potentially by a
couple days even.
Proper surveillance is also crucial, Hayes noted.
"Emergency surveillance samples were collected in one day

and test results completed within 48 hours," she said. Hatcher
suggested increasing testing during time of high risk.
Preparing for an outbreak of Avian Influenza
Hayes suggests making sure equipment and supplies
are ready to go should an outbreak occur. A plan might include having a mobile response trailer, mobile shower and
restroom trailer for burial sites, she added. Keep inventory
of your supplies too. Know what kind of equipment you
will need at each site and have it readily available.
It is also important to monitor employee health and
fatigue when managing these situations.
"Collaborate and communicate," Hatcher said. Make
sure everyone understands how to follow the plan before
actions need to take place. "Trained and experienced
strike teams for depopulation and disposal would be nice."
Producers should make decisions based on high risk or
worst case scenario situations.
"Use your common sense," Hatcher said.
He asked to help with future planning and management practices by support funding for state and federal
disease prevention and control efforts. ■
