An efficient and effective swine herd health
program addresses proper nutrition, housing,
and ventilation; animal welfare and comfort;
appropriate pharmaceutical use; and disease
prevention and control strategies. Biosecurity
is the cornerstone of disease prevention. By
implementing biosecurity precautions, the herd
can be protected from the entry of potentially
classical swine fever, brucellosis, pseudorabies
and circovirus infections. The biggest threat is
purchased pigs that may harbor infectious
agents, without exhibiting overt clinical signs.
Wildlife, pets, people, inanimate objects, and
wind can carry disease-causing organisms onto
a swine facility. The California Department of
Food and Agriculture’s (CDFA) Animal Health
Branch, in partnership with the National Pork
Producers Council, State associations, the
United States Department of Agriculture
Cooperative Extension are committed
assisting producers in developing biosecurity
strategies. The following biosecurity principles
