The invention provides a method and compositions for controlling food
borne enteric bacterial pathogens in animals. Populations of
enteropathogenic bacteria may be substantially reduced or eliminated by
treatment of animals with an effective amount of 2-nitropropanol,
2-nitroethane or 2-nitroethanol. The compounds may be administered
orally, providing a reduction in the populations of the enteropathogenic
bacteria in the alimentary tract of the animal, or they may be applied
externally onto the animal to reduce the populations of any such bacteria
which may be present as contaminants on the surface of the animal. The
method and compositions are particularly useful for the control of
Salmonella species, enteropathogenic Escherichia coli, Campylobacter
species, and Listeria monocytogenes.
