Abstract: Methods and compositions are hereby disclosed for reducing the numbers of E. coli O157:H7, Salmonella or other pathogens in an animal. The methods include administering to the animal a lactic acid producing bacterium at a relatively low dosage in combination with a lactate utilizing bacterium, followed by administration of the lactic acid producing bacterium at a relatively high dosage. The disclosed methods help achieve pre-harvest food safety and enhance feed performance while keeping the total cost relatively low. The preferred lactic acid producing bacterium is Lactobacillus acidophilus/animalis and the preferred lactate utilizing bacterium is Propionibacterium freudenreichii.

Abstract: The invention includes methods and compositions for treating an animal to inhibit the incidence and growth of E. coli O157:H7 and other pathogenic bacteria. The treatment method comprises administering a therapeutically effective amount of Lactobacillus acidophilus or one or a combination of a number of other probiotic bacteria to an animal. An alternative treatment method comprises administering a therapeutically effective amount of a lactic acid producing bacterium such as Lactobacillus acidophilus in combination with a lactate utilizing bacterium such as Propionibacterium freudenreichii.

Abstract: Compositions and methods useful for reducing or eliminating the presence of pathogens in meat and meat products are disclosed. Administration of one or more lactic acid producing microorganisms to a live animal, to a carcass, to meat, to meat products, or in animal feed results in significant reductions in the amount of pathogens potentially harmful to humans when ingested. Synergistic effects can be achieved with the administration of multiple strains of microorganisms.
