Abstract: A laboratory method and a test specimen for efficiently and accurately assessing and validating the efficacy of an antimicrobial to treat pathogens on a beef carcass. The method and model employ one or more carcasses from calves that have not received colostrum.

Abstract: Compositions and methods useful for reducing or eliminating the presence of pathogens in meat or 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.

Abstract: The present invention includes a method for extending the shelf-life of one or more foods by exposure to one or more pulses of microwave radiation for at least seven (7) seconds. The present invention may also be used to reduce pathogenic organisms in food. The one or more foods may be packaged within a container, sealed and stored.

Abstract: The present invention provides methods and compositions for preventing or inhibiting human food-borne pathogens in animals, and methods for increasing feed efficiency in animals by administering to the animal effective amounts of probiotic lactic acid producing bacteria. Further provided are feed compositions comprising probiotic lactic acid producing bacteria. A preferred probiotic lactic acid producing bacteria is Lactobacillus acidophilus strain ATCC accession number PTA-5249. This bacterial strain inhibits nalidixic acid-resistant Escherichia coli 0157:H7.
