cial and breeding operations in the layer industry. For a
plan to be effective, Schaal said they first had to figure
out where the virus introduced itself on the farms.
"Investment and education preparation are the
golden standards by which biosecurity can succeed,"
Schaal said. Since 2005, or about that time, U.S. producers and industry members knew the AI virus from
Asia could come to the U.S. via migratory birds. A
decade later, that concept became reality.
Producers should be prepared for the next challenge, the next AI or the next emerging disease
through a robust biosecurity plan to protect their investment, he said.
The plan - critical considerations
"The plan itself is more a discussion document,"
Schaal said. It is full of questions to ask yourself and
your operation, your upper management and your farm
staff in a conversational way to understand what's truly
happening on your farm.
"It's meant to be the global standard," he said.
The plan offers general topics and considerations
that can match any size operation. While the plan is
intended for AI, it could be transferred to any other
communicable poultry pathogen.
All-in, all-out farm design and planning is ideal,
however not always feasible. Apply all-in, all-out principles to each barn, he said.
"What can we do to limit the exposure of moving birds on and off a complex to reduce risk? Where there are
birds, there is potentially disease, and
when they move, they can take things
with them," he said.
Site management must establish and
control a well-defined clean/dirty line.
This may be at the farm gate and chicken house door. One should consider all
farm inputs dirty until cleaning or disinfecting. All farm personnel, visitors,
vendors or contract crews must follow
all farm biosecurity standard operation procedures at all times. Operators
should track all inputs and outputs on
the farm including people, vehicles,
equipment and even pullets/layers.
Trucking is an area of high risk for
potentially introducing disease. Bird
movement between farms, to slaughter or disposal are all risk factors for
disease introduction or transmission.
The movement of manure is also a risk.
"Land application of manure is a perfect avenue to bring in disease to your
neighbors some distance away," Schaal said.
AI virus from affected manure hauled or spread
could be on the farm 10 days before clinical signs
appear. It is important to have a passive surveillance
testing program in place to ensure AI-negative status.
There must be separation between companies handling
