摘要

沙门氏菌是一种威胁食品安全和公众健康的食源性人畜共患病。然而,很少有人对烟台市食品中的沙门氏菌污染情况进行长期、系统的研究。为了解烟台市食品中沙门氏菌污染情况,提高食源性疾病的预警和控制能力,从 2010 年至 2023 年,在烟台市 13 个监测点共采集了 20 类 3420 份样品。比较了不同监测点、不同类型、不同来源样品的检出率和菌株差异。在 3420 份样品中,有 80 份呈阳性,检出率为 2.34%。在不同监测点采集的样本,沙门氏菌检出率有明显差异。沙门氏菌只在肉类、肉类制品和餐饮食品中检出,其他种类的沙门氏菌均未检出。未 经 烹 煮 的 动 物 肉 类 和 未 经 烹 煮 的 家 禽 的 沙 门 氏 菌 检 出 率 较 高 。在街市收集的样本检出率最高(5.81%),不同来源的样本检出率有显著差异(χ2 = 36.93,P < 0.05)。在 3420 个样本中检测出 81 个沙门氏菌菌株(1 个阳性样本中检测出 2 个不同菌株)。血清学检测确定了 8 个组别和 27 个血清型。主要血清群为 B 群 30.86%(25/81)、E1 群 23.46%(19/81)和 D 群 16.05%(13/81)。主要的血清型为给沙门氏菌 17.28%(14/81)、肠炎沙门氏菌 16.05%(13/81)和德比沙门氏菌 13.58%(11/81)。肉类和肉类制品以及餐饮食品是受沙门氏菌污染的主要食品。由此造成的二次污染是食源性疾病的隐患,应引起足够重视。

Contamination Status and Serotypes Distribution of Salmonella in Food in Yantai City, China: A 14-Year Continuous Monitoring Study.

Salmonella is a foodborne zoonotic pathogen that threatens food safety and public health. However, few people have conducted long-term and systematic studies on Salmonella contamination in food in Yantai City. In order to investigate the situation of Salmonella contamination in food and improve the ability of early warning and control of foodborne diseases, a total of 3420 samples from 20 categories were collected from 13 monitoring points in Yantai City, from 2010 to 2023. The difference in detection rate and bacterial strain of different monitoring points, different types, and different sources of samples was compared. Of the 3420 samples, 80 were positive with a detection rate of 2.34%. Salmonella detection rates were significantly different for samples collected at different monitoring sites. Salmonella was detected only in meat and meat products and catering food, and none of the other types were detected. The detection rate of Salmonella was higher in raw animal meat and raw poultry. Samples collected at the market stage had the highest detection rate (5.81%), and there was a significant difference in detection rate between samples from different sources (χ2 = 36.93, p < 0.05). Eighty-one strains of Salmonella were detected out of 3420 samples (2 different strains were detected in 1 positive sample). The serological test identified 8 groups and 27 serotypes. The dominant serum groups were group B 30.86% (25/81), group E1 23.46% (19/81), and group D 16.05% (13/81). The main dominant serotypes were Salmonella give 17.28% (14/81), Salmonella enteritidis 16.05% (13/81), and Salmonella derby 13.58% (11/81). Meat and meat products and catering food were the main food products contaminated with Salmonella. The resulting secondary contamination is the hidden threat of foodborne diseases and should be given sufficient attention.

期刊介绍: Foodborne Pathogens and Disease is one of the most inclusive scientific publications on the many disciplines that contribute to food safety. Spanning an array of issues from "farm-to-fork," the Journal bridges the gap between science and policy to reduce the burden of foodborne illness worldwide. Foodborne Pathogens and Disease coverage includes: Agroterrorism Safety of organically grown and genetically modified foods Emerging pathogens Emergence of drug resistance Methods and technology for rapid and accurate detection Strategies to destroy or control foodborne pathogens Novel strategies for the prevention and control of plant and animal diseases that impact food safety Biosecurity issues and the implications of new regulatory guidelines Impact of changing lifestyles and consumer demands on food safety.
