Salmonella and Campylobacter are significant issues for poultry processors because of increasing regulatory standards as well as public health concerns. The goal of this study is to report the effects of two different pre-chiller systems that utilize different temperatures and water recirculation systems on whole bird carcass rinsates. Both pre-chiller tanks were contained within a single poultry processing facility and operated at different temperatures and water systems. The incidence of Campylobacter spp. and Salmonella spp., as well as the aerobic plate counts on whole bird carcass rinses are reported in this study from each pre-chiller system. The results from this study reveal that there are significant differences in how microbial populations and pathogens change over time in each pre-chiller system. Furthermore, we identify that these patterns are different per system. Such data are impactful as it indicates that measuring carcasses within a plant must consider both temperature and water recirculation as it may prevent comparability of different lines within a single processing facility.

商用家禽加工厂中采用不同水管理策略的预冷器中整个禽car体冲洗液的好氧板数，沙门氏菌和弯曲杆菌负荷。

沙门氏菌和弯曲杆菌对家禽加工者来说是重要的问题，因为监管标准的提高以及对公共卫生的关注。这项研究的目的是报告两种不同的预冷器系统，它们利用不同的温度和水循环系统对整个禽类屠体冲洗液产生影响。两个预冷水箱都装在一个家禽加工设施中，并在不同的温度和水系统下运行。弯曲杆菌属的发生率。本研究报告了每个预冷器系统中沙门氏菌和沙门氏菌的种类以及整个禽car体冲洗液中需氧板的数量。这项研究的结果表明，每个预冷器系统中微生物种群和病原体随时间变化的方式存在显着差异。此外，我们发现这些模式在每个系统中都是不同的。这样的数据具有影响力，因为它表明在工厂内测量屠体必须同时考虑温度和水的再循环，因为这可能会阻止单个加工设施内不同生产线的可比性。
