Summary

ALL BACTERIA STUDIED (STAPHYLOCOCCUS AUREUS, BACILLUS CEREUS, YERSINIA ENTEROCOLITICA, SALMONELLA ENTERITIDIS AND SALMONELLA TYPHIMURIUM) WERE INFLUENCED BY NITRITE ADDITION (0, 75 OR 150 PPM). S. AUREUS DID NOT DEVELOP IN PACKAGES WITH 75 PPM ADDED NITRITE, BUT MULTIPLIED WITHOUT NITRITE AT 283 K (10 DEG C). AT 283 K S. ENTERITIDIS HAD A LONG LAG PHASE WITH 75 PPM ADDED NITRITE BUT NOT AT 285 K (12 DEG C). OTHER BACTERIA WERE LESS AFFECTED. RECOMMENDED TEMPERATURES OF 278 K (5 DEG C) IN COMBINATION WITH HIGH LEVELS OF NITRITE (150 PPM) WAS NOT ADEQUATE IN PREVENTING GROWTH OF Y. ENTEROCOLITICA, AND AT TEMPERATURES OF 283-285 K (10-12 DEG C) ALSO B. CEREUS AND SALMONELLAE DEVELOPED IN SPITE OF NITRITE ADDITION.
