Background Non-typhoidal Salmonella (NTS) is a serious foodborne pathogen that has previously been isolated from pigs presented for slaughter in a rural pork value chain in western Kenya. Methods To understand varying NTS contamination along the value chain we assessed prevalence at slaughter, transport and retail. Suspect isolates from culture were confirmed using matrix-assisted laser desorption-ionization time of flight mass spectrometry. Results Prevalence on pig carcasses, meat transportation containers, retailed raw and cooked pork and accompanying side salads was 18.1%, 23.9%, 28.0%, 1.9% and 8.6%, respectively. Conclusion NTS contamination is propagated along the pork value chain in rural western Kenya, demonstrating the need for improved hygiene measures to prevent human exposure.

东非农村地区猪肉价值链上的非伤寒沙门氏菌污染：一项横断面研究

背景 非伤寒沙门氏菌 (NTS) 是一种严重的食源性病原体，之前已从肯尼亚西部农村猪肉价值链中待屠宰的猪中分离出来。方法 为了了解价值链上不同的 NTS 污染，我们评估了屠宰、运输和零售的流行情况。使用基质辅助激光解吸电离飞行时间质谱法确认培养物中的可疑分离株。结果 生猪屠体、肉类运输容器、零售生熟猪肉以及配菜沙拉中的患病率分别为18.1%、23.9%、28.0%、1.9%和8.6%。结论 NTS 污染沿着肯尼亚西部农村地区的猪肉价值链传播，表明需要改进卫生措施以防止人类接触。
