Experiments were conducted to determine the effect that temperature mishandling at various times during storage has on detection of temperature abuse of fresh broiler chicken carcasses using populations of mesophilic and coliform bacteria as indicators of abuse. Forty-five broiler carcasses were used in each of three independent trials. Five carcasses were analyzed at day of collection (Treatment 0 control). Five carcasses, on each day of the next 7 d (Treatments 1 to 7) were temperature-abused for 12 h at 25 C, stored at 3 C until Day 9, and then sampled. The five remaining carcasses were stored at 3 C and sampled on Day 9 (Treatment 8 control). Carcasses were sampled using a whole carcass rinse procedure and assayed for aerobic plate counts (APC), total coliform counts (TCC), impedance detection times (DT), and impedance coliform detection times (DTCM). Although significant differences were noted using all four microbiological methods, temperature abuse at different times during storage had no consistent effect on populations of mesophilic or coliform bacteria; therefore, temperature abuse determinations may be conducted without regard to the day on which the carcasses were subjected to elevated temperatures.
进行了实验，以确定在储存期间不同时间温度处理不当对使用嗜温菌和大肠菌群作为滥用指标来检测新鲜肉鸡胴体温度滥用情况的影响。在三个独立试验中，每个试验使用45只肉鸡胴体。在收集当天分析5只胴体（处理0，对照）。在接下来7天的每一天，对5只胴体（处理1至7）在25℃下进行12小时的温度滥用处理，在3℃下储存至第9天，然后进行采样。其余5只胴体在3℃下储存，并在第9天进行采样（处理8，对照）。使用全胴体冲洗程序对胴体进行采样，并测定需氧平板计数（APC）、总大肠菌群计数（TCC）、阻抗检测时间（DT）和阻抗大肠菌群检测时间（DTCM）。尽管使用所有四种微生物学方法都发现了显著差异，但储存期间不同时间的温度滥用对嗜温菌或大肠菌群数量没有一致的影响；因此，温度滥用的测定可以不考虑胴体经受高温的日期进行。
