Cooked poultry cuts were inoculated with five-strain composite mixtures of either Listeria monocytogenes or Yersinia enterocolitica (1,000 CFU/150-g piece), packaged in 44:56 CO2-N2, and stored at 3.5, 6.5, or 10 degrees C for up to 5 weeks. Both L. monocytogenes and Y. enterocolitica grew under all test conditions. The presence of a naturally occurring microbiota did not influence the growth of either pathogen. Addition of lactate with the shelf life extender ALTA 2341 lengthened the lag phases of L. monocytogenes and Y. enterocolitica but did not prevent their growth.
将熟禽肉块接种单核细胞增生李斯特菌或小肠结肠炎耶尔森菌的五菌株复合混合物(1000 CFU/150克肉块),包装在44:56的二氧化碳 - 氮气中,并在3.5、6.5或10摄氏度下储存长达5周。单核细胞增生李斯特菌和小肠结肠炎耶尔森菌在所有测试条件下均生长。天然存在的微生物群的存在不影响任何一种病原体的生长。添加乳酸与保质期延长剂ALTA 2341延长了单核细胞增生李斯特菌和小肠结肠炎耶尔森菌的迟缓期,但并未阻止它们的生长。
