Summary

ELECTRICAL STIMULATION OF BEEF CARCASSES DID NOT CAUSE A SIGNIFICANT REDUCTION IN SURFACE MICROBIAL POPULATION AT THREE DIFFERENT SAMPLING POSITIONS IMMEDIATELY FOLLOWING SLAUGHTER. HOWEVER, SIGNIFICANT MICROBIAL REDUCTION (P LOWER THAN 0.05) WAS FOUND AFTER 72 H OF CHILLING STORAGE. NINE BACTERIAL SPECIES FROM EIGHT DIFFERENT GENERA COMMONLY ASSOCIATED WITH MEAT WERE INOCULATED ON THREE DIFFERENT AGAR MEDIA WHICH VARIED IN ELECTRICAL CONDUCTIVITY. ELECTRICAL STIMULATION OF THESE MEDIA CAUSED A REDUCTION IN NUMBERS OF MICROORGANISMS UNDER VARIOUS VOLTAGE AND TIME TREATMENTS. SPORE-FORMING BACTERIA WERE THE MOST RESISTANT TO THE ELECTRICAL TREATMENTS.
