Salmonella remains one of the most prevalent zoonoses worldwide. Although salmonellosis is commonly associated with the consumption of contaminated food, it has been estimated that up to 11% of Salmonella infections overall are acquired from direct or indirect contact with animals, including reptiles. In 2016, an outbreak of Salmonella Enteritidis involving multiple cases, especially children, associated with reptile contact and contaminated feeder mice was reported in the United Kingdom. The aim of this study was to investigate Salmonella external and internal contamination of stored commercial frozen feeder mice used to feed reptiles and obtained from the same supplier involved in the outbreak. In this study a total of 295 mice were tested (60 pinkies, 60 fuzzies, 60 small, 60 large, and 55 extra large). In this study, both external (integument) and internal (selected organs) contamination were evaluated. Salmonella Enteritidis PT8 and PT13 were isolated from 28.8% (n = 17) of the 59 batches tested, with the exception of the large mice category. Positive mice were mostly contaminated externally (92.3% vs. 26.9% for carcass wash and viscera, respectively). All isolates were sensitive to all 16 antimicrobials tested. The high level of external contamination of the rodent carcasses might have played a role in the human outbreak in 2016. Reptile owner management of the rodent carcasses at home could be an important source of salmonellosis outbreaks. Collaboration among public health officials, pet industry, veterinarians, and reptile owners is needed to help prevent the risk of salmonellosis associated with animal-based food intended for reptiles.
沙门氏菌仍然是全球最普遍的人畜共患病之一。尽管沙门氏菌病通常与食用受污染的食物有关，但据估计，总体上高达11%的沙门氏菌感染是通过与动物（包括爬行动物）直接或间接接触而获得的。2016年，英国报告了一起肠炎沙门氏菌疫情，涉及多起病例，尤其是儿童，与接触爬行动物和受污染的饲料小鼠有关。本研究的目的是调查用于喂养爬行动物且从疫情中涉及的同一供应商处获得的商业冷冻饲料小鼠的外部和内部沙门氏菌污染情况。在本研究中，共检测了295只小鼠（60只乳鼠、60只幼鼠、60只小老鼠、60只大老鼠和55只特大老鼠）。在本研究中，对外部（体表）和内部（选定器官）污染均进行了评估。除大老鼠类别外，从59批测试小鼠中分离出肠炎沙门氏菌PT8和PT13的比例为28.8%（n = 17）。阳性小鼠大多为外部污染（胴体清洗液和内脏分别为92.3%和26.9%）。所有分离株对所有16种测试抗菌药物均敏感。啮齿动物尸体的高外部污染水平可能在2016年的人类疫情中起到了作用。爬行动物主人在家中对啮齿动物尸体的处理可能是沙门氏菌病爆发的一个重要来源。公共卫生官员、宠物行业、兽医和爬行动物主人之间需要开展合作，以帮助预防与用于爬行动物的动物性食物相关的沙门氏菌病风险。
