Dried non-heat-treated meat treats, such as ears, skin and tails, are popular supplementary dog foods. Previous studies have demonstrated Salmonella spp. contamination on treats, particularly in pig ears and chicken products. This small, exploratory, cross-sectional study investigated Salmonella spp. presence in dried treats available in the UK.
A selection of dried treats from local pet shops and online retailers underwent bacterial culture for Salmonella spp. and subsequent antimicrobial susceptibility testing, with Salmonella serotype determined by whole genome sequencing.
Eighty-four samples were tested, with 16% being Salmonella spp. positive. Five Salmonella serotypes were identified, each associated with specific treat types. An antimicrobial-resistant phenotype was identified in 39% of isolates. All serotypes identified are known to cause human infection.
This study was limited by a small sample size and limited number of retail sources.
Salmonella spp. of public health concern were present in some dried dog treats in this study. Dog owners, pet food retailers and veterinary professionals should be aware of the potential zoonotic disease risk associated with these treats, and appropriate hygiene measures, including thorough hand washing, should be utilised if they are fed.
干制未经热处理的肉类零食，如耳朵、皮和尾巴，是受欢迎的狗狗补充食物。先前的研究表明，零食上存在沙门氏菌污染，尤其是在猪耳朵和鸡肉产品中。本项小型探索性横断面研究调查了在英国可获得的干制零食中沙门氏菌的存在情况。
从当地宠物店和在线零售商处选择了一些干制零食，对其进行沙门氏菌的细菌培养和随后的药敏试验，通过全基因组测序确定沙门氏菌血清型。
共检测了 84 个样本，其中 16%呈沙门氏菌阳性。鉴定出 5 种沙门氏菌血清型，每种血清型都与特定的零食类型相关。在 39%的分离株中发现了具有抗药性的表型。所有鉴定出的血清型都已知会导致人类感染。
本研究受到样本量小和零售来源有限的限制。
在本研究中，一些干制狗零食中存在公共卫生关注的沙门氏菌。狗主人、宠物食品零售商和兽医专业人员应意识到这些零食可能存在与人类相关的动物传染病风险，应采取适当的卫生措施，包括彻底洗手，如果要喂食这些零食应采取这些措施。
