Chicken meat can potentially become contaminated with bacteria at the processing plant. In Australia, there is currently a lack of knowledge on the parameters and indications of use of non-chlorine based treatments in the chicken meat processing plants. Chlorine is widely used as a sanitizer in Australian chicken meat processing plants but due to occupational health and safety concerns and consumer perception, there is a need to identify alternative sanitizers. This study aimed to assess the efficacy of four different sanitizers in reducing the microbial load from naturally contaminated chicken meat carcasses collected from the processing plants in South Australia. There was a significant variation in a load of and total viable count (TVC) between samples collected from two different processing plants and within carcass batches collected from the same plant that was tested during the study. All sanitizers generally reduced the load of on chicken meat carcasses. Treatment with acidified sodium chlorite significantly reduced the level of Salmonella enterica serovars at all temperatures tested during this study. These findings are helpful to the industry for selection of the appropriate sanitizers. Findings are also useful for the regulatory authorities in Australia for providing approval for the use of sanitizers.
鸡肉在加工厂可能受到细菌污染。在澳大利亚，目前对于非氯处理在鸡肉加工厂的使用参数和指示缺乏了解。在澳大利亚的鸡肉加工厂，氯被广泛用作消毒剂，但由于职业健康和安全问题以及消费者认知，需要确定替代消毒剂。本研究旨在评估四种不同消毒剂在减少从南澳大利亚加工厂采集的受自然污染鸡肉胴体的微生物负荷方面的功效。在本研究中，从两个不同加工厂采集的样品之间以及从同一加工厂采集的胴体批次之间的载量和总活菌计数（TVC）存在显著差异。所有消毒剂通常都减少了鸡肉胴体上的载量。酸化亚氯酸钠处理显著降低了本研究中所有测试温度下的肠炎沙门氏菌血清型的水平。这些发现有助于业界选择合适的消毒剂。这些发现也有助于澳大利亚监管机构批准消毒剂的使用。
