Abstract

Non-typhoidal Salmonella enterica (NTS) are significant foodborne pathogens responsible for many cases of enterocolitis worldwide, with the increasing threat of antimicrobial resistance (AMR) posing a growing public health concern. Salmonella Infantis has emerged as a predominant multidrug-resistant (MDR) serotype, particularly in poultry. This study investigated the Salmonella prevalence in 200 chicken meat samples from Swiss retail stores. Six (3%) samples tested positive; all were imported, and the isolates were all identified as S. Infantis. Whole genome sequencing confirmed the presence of the pESI (plasmid of emerging S. Infantis) megaplasmid, which is associated with enhanced persistence, biofilm formation, and multidrug resistance. Statistical analysis revealed a significant correlation between Salmonella prevalence and imported, unlabeled products. These findings highlight the effectiveness of Swiss control measures in the poultry production but underscore the importance of maintaining consumer awareness to mitigate Salmonella transmission and MDR risks.

瑞士和进口零售鸡肉中的沙门氏菌-一项横断面研究。

非伤寒沙门氏菌（NTS）是全球许多小肠结肠炎病例的重要食源性病原体，抗菌素耐药性（AMR）的威胁日益增加，引起了日益严重的公共卫生问题。婴儿沙门氏菌已成为一种主要的耐多药血清型，特别是在家禽中。本研究调查了瑞士零售商店200份鸡肉样品中沙门氏菌的流行情况。6个（3%）样本检测呈阳性；全部为输入性，分离株均鉴定为婴儿链球菌。全基因组测序证实了pESI（新生婴儿链球菌质粒）巨型质粒的存在，它与增强的持久性、生物膜形成和多药耐药性有关。统计分析显示，沙门氏菌流行率与进口无标签产品之间存在显著相关性。这些发现强调了瑞士控制措施在家禽生产中的有效性，但强调了保持消费者意识以减轻沙门氏菌传播和耐多药风险的重要性。

期刊介绍： The Journal of Food Protection® (JFP) is an international, monthly scientific journal in the English language published by the International Association for Food Protection (IAFP). JFP publishes research and review articles on all aspects of food protection and safety. Major emphases of JFP are placed on studies dealing with: Tracking, detecting (including traditional, molecular, and real-time), inactivating, and controlling food-related hazards, including microorganisms (including antibiotic resistance), microbial (mycotoxins, seafood toxins) and non-microbial toxins (heavy metals, pesticides, veterinary drug residues, migrants from food packaging, and processing contaminants), allergens and pests (insects, rodents) in human food, pet food and animal feed throughout the food chain; Microbiological food quality and traditional/novel methods to assay microbiological food quality; Prevention of food-related hazards and food spoilage through food preservatives and thermal/non-thermal processes, including process validation; Food fermentations and food-related probiotics; Safe food handling practices during pre-harvest, harvest, post-harvest, distribution and consumption, including food safety education for retailers, foodservice, and consumers; Risk assessments for food-related hazards; Economic impact of food-related hazards, foodborne illness, food loss, food spoilage, and adulterated foods; Food fraud, food authentication, food defense, and foodborne disease outbreak investigations.
