ABSTRACT Several foodborne pathogens, including
Salmonella species and campylobacters, are common contaminants
in poultry and livestock. Typically, these
pathogens are carried in the animal’s intestinal tract
asymptomatically; however, they can be shed in feces in
large populations and be transmitted by other vectors
from feces to animals, produce, or humans. A wide array
of interventions has been developed to reduce the carriage
of foodborne pathogens in poultry and livestock, including
genetic selection of animals resistant to colonization,treatments to prevent vertical transmission of enteric
pathogens, sanitation practices to prevent contamination
on the farm and during transportation, elimination of
pathogens from feed and water, feed and water additives
that create an adverse environment for colonization by
the pathogen, and biological treatments that directly or
indirectly inactivate the pathogen within the host. To
successfully reduce the carriage of foodborne pathogens,
it is likely that a combination of intervention strategieswill be required.
