研究了254 nm紫外线照射对肉鸡肉、皮和屠体表面空肠弯曲菌存活的影响。在肉鸡尸体上，还研究了紫外线与活性氧结合的影响。表面接种不同数量的C。空肠，并用剂量范围为9.4 - 32.9mW/s/平方厘米的UV照射处理。C的对数减少。通过稀释平板法测定空肠计数。还评估了这两种处理对肉鸡肉感官品质的影响，包括视觉外观、气味和脂肪酸组成。在肉鸡肉上，达到的最大减少量为0.7 log，在肉鸡皮肤上为0.8 log。在肉鸡尸体上，使用紫外线照射的最大减少量为0.4 log，使用紫外线与活性氧结合的最大减少量为0.4 log。样品和对照之间的感官质量没有显着差异。单独使用紫外线照射或结合活性氧不能推荐作为C.肉鸡尸体上的空肠。这些方法与其他去污技术相结合，并在适当的加工厂卫生条件下进行加工，可能会更有效地降低C。与仅使用这些方法相比，肉鸡胴体表面上的空肠计数更高。
The effects of UV irradiation at a wavelength of 254 nm on the survival of Campylobacter jejuni on the surfaces of broiler meat, skin, and carcasses were studied. On broiler carcasses, the effects of UV were also studied in combination with activated oxygen. The surfaces were inoculated with varying counts of C. jejuni and treated with UV irradiation using doses ranging between 9.4 and 32.9 mW/s per square centimeter. The log reductions in C. jejuni counts were determined by dilution plating. The effects of both treatments on the sensory quality of broiler meat, including visual appearance, odor, and fatty acid composition, were also evaluated. On broiler meat, the maximum reduction achieved was 0.7 log and on broiler skin 0.8 log. On broiler carcasses, the maximum reduction using UV irradiation was 0.4 log, and using UV in combination with activated oxygen 0.4 log. No significant differences were found in the sensory quality between the samples and the controls. The use of UV irradiation alone or in combination with activated oxygen cannot be recommended as a primary decontamination method for C. jejuni on broiler carcasses. The use of these methods in combination with other decontamination techniques, and processing with proper processing plant sanitation and hygiene, might be more effective in reducing the C. jejuni counts on broiler carcass surfaces than the use of these methods only.
