Dead poultry - carrying certain diseases or pathogens you can take that back to the farm with you. Should be your last stop of the day.

27
Q

Do gas stations or restaurants impose a biosecurity risk?

A

Yes, not everyone is practicing biosecurity as well as you and sometimes are tracking things with them in a common place

28
Q

Why is on-sight disposal preferred over off-sight disposal?

A

You don’t need to worry about someone walking in or someone taking something out of the farm

Low impact transmissible disease:
Moderately high impact disease:
Foreign Animal Disease of high
consequence:

Why might this type of plan potentially lead to compliance
issues?

A

Peacetime: Green
Low impact transmissible disease: Yellow
Moderately high impact disease: Orange
Foreign Animal Disease of high
consequence: Red

More difficult you make something the less likely the staff member will want to do it.

31
Q
