Abstract

The aim of this study was to evaluate the effect of UV-C light (254-nm wavelength, minimum intensity 0.573 mW/cm²) on the presence of Salmonella spp. and the counts of Enterobacterales in various raw chicken parts. Salmonella spp. was initially detected in 16 out of 20 samples. Following UV-C treatment, the prevalence of Salmonella spp. positive samples progressively decreased with 13 positive samples remaining after 3 h and further reduction to seven samples after 6 h of exposure. Complete inactivation of Salmonella spp. was observed following after 9, 12, and 24 h of UV-C application, ensuring microbiological safety in accordance with food safety standards. Additionally, Enterobacterales counts also showed significant reductions, particularly between 6 and 12 h of UV-C treatment. These findings highlight UV-C light as a promising intervention for mitigating foodborne pathogens in poultry products, with potential for practical applications in food safety systems. Further research with a larger number of samples is recommended to optimize UV-C treatment for controlling foodborne pathogens in poultry food products.

紫外光处理对生鸡肉制品中肠杆菌和沙门氏菌影响的研究。

本研究旨在评价UV-C光（波长254 nm，最小强度0.573 mW/cm2）对生鸡肉各部位沙门氏菌和肠杆菌数量的影响。最初在20个样本中的16个样本中检测到沙门氏菌。经过UV-C处理后，沙门氏菌阳性样本的患病率逐渐下降，暴露3小时后仍有13个阳性样本，暴露6小时后进一步减少到7个样本。在UV-C照射9、12和24 h后，沙门氏菌完全失活，确保微生物安全符合食品安全标准。此外，肠杆菌数量也显示出显著减少，特别是在UV-C处理6至12小时之间。这些发现强调了UV-C光作为一种有希望的干预措施，可以减轻家禽产品中的食源性病原体，在食品安全系统中具有实际应用的潜力。建议进行更多样品的进一步研究，以优化UV-C处理方法，以控制家禽食品中的食源性病原体。

期刊介绍： Veterinary Medicine and Science is the peer-reviewed journal for rapid dissemination of research in all areas of veterinary medicine and science. The journal aims to serve the research community by providing a vehicle for authors wishing to publish interesting and high quality work in both fundamental and clinical veterinary medicine and science. Veterinary Medicine and Science publishes original research articles, systematic reviews, meta-analyses, and research methods papers, along with invited editorials and commentaries. Original research papers must report well-conducted research with conclusions supported by the data presented in the paper. We aim to be a truly global forum for high-quality research in veterinary medicine and science, and believe that the best research should be published and made widely accessible as quickly as possible. Veterinary Medicine and Science publishes papers submitted directly to the journal and those referred from a select group of prestigious journals published by Wiley-Blackwell. Veterinary Medicine and Science is a Wiley Open Access journal, one of a new series of peer-reviewed titles publishing quality research with speed and efficiency.
