Fresh chicken breast meats inoculated with Yersinia enterocolitica and Aeromonas hydrophila were packaged in glass jars containing different compositions of modified atmospheres (MA) (100% CO2; 80% CO2/20% N-2), in vacuum and in air and stored at 3+/-1 degrees C and 8+/-1 degrees C. The changes in gas composition, Y. enterocolitica, A. hydrophila, total aerobic bacterial, total psychrotrophic, Lactobacillus and Enterobacteriaceae counts were determined after 0, 1, 3, 7, 9, 11, and 14 days of storage. The results show that while the growth of Y. enterocolitica and A. hydrophila were retarded under MA storage, the pathogens were capable of growth in MA and vacuum storage at both temperatures, for studying inoculation levels. For total aerobic bacterial counts, there were no differences between chicken breasts meats held in different atmospheres. Co-2 packaging has the highest inhibiting effect on the growth of psycrotrophic aerobic bacteria during the first 3 days. Lactic acid bacteria of samples stored in MA and in vacuum increased rapidly when compared to those stored in air. It was also found that, the effect of MA storage increased at 3+/-1 degrees C.
