摘要
The aim of this study was to determine the survival of Campylobacter jejuni in chicken meat samples at frozen temperatures and given length of incubation and to determine the impact of aerobic bacteria on the survival of C. jejuni. The chicken meat samples were inoculated with C. jejuni NCTC 11351 suspensions and stored in bags at temperatures of -20 degrees C and -70 degrees C. The mean value of C. jejuni from meat samples decreased from 7.52 log(10) CFU/g after 30 minutes of incubation at ambient temperature, to 3.87 log(10) CFU/g on the eighth week of incubation at -20 degrees C, and to 3.78 log(10) CFU/g at incubation at -70 degrees C after the same incubation period. Both freezing temperatures, -20 degrees C and -70 degrees C, decreased the number of campylobacters. The presence of aerobic mesophilic bacteria did not influence the survival of C. jejuni in chicken meet samples. Keeping poultry meat at freezing temperatures is important for the reduction of C. jejuni, which has a strong influence on the prevention of occurrence of campylobacteriosis in humans.
