The consumption of insects as food and feed has been recently suggested as a possible alternative to the rising global food need, thus it is crucial to monitor any potential food safety hazards in the insect supply chain. The aims of this systematic review were to collect, select, and evaluate studies investigating the persistence of Salmonella in insects. We searched PUBMED, EMBASE, WEB of Science Core Collection, and Food Science and Technology Abstracts. In total, 36 papers investigating the persistence of Salmonella in insects (both holometabolous and heterometabolous) were included after screening. Regarding complete metamorphosis insects, the longest Salmonella persistence was reported in Phormia regina, in which the pathogen persisted for 29 days at 5 °C. Similarly, Salmonella persisted in the feces of Alphitobius diaperinus for 28 days. The incomplete metamorphosis insect showing the longest Salmonella persistence (>10 months) was Blatella germanica. Periplaneta americana excreted Salmonella via feces for 44 days until all the insects were dead. The retrieved data on the persistence of Salmonella can be useful for further analysis by risk assessors and decision-makers involved in the safety of insect-based food, contributing to defining the sanitary requirements and risk mitigation measures along the supply chain. The review protocol is registered in PROSPERO database (CRD42022329213).
最近有人提出，食用昆虫作为食物和饲料可能是应对全球粮食需求不断增长的一种替代方案，因此监测昆虫供应链中的任何潜在食品安全危害至关重要。本系统综述的目的是收集、筛选和评估研究沙门氏菌在昆虫体内持久性的研究。我们检索了PubMed、Embase、科学网核心合集和食品科学与技术文摘数据库。经过筛选，总共纳入了36篇研究沙门氏菌在昆虫（全变态和不完全变态）体内持久性的论文。对于完全变态昆虫，在丽蝇中报道的沙门氏菌持续时间最长，该病原体在5°C下持续存在29天。同样，沙门氏菌在赤拟谷盗的粪便中持续存在28天。沙门氏菌持续时间最长（超过10个月）的不完全变态昆虫是德国小蠊。美洲大蠊通过粪便排泄沙门氏菌达44天，直到所有昆虫死亡。检索到的关于沙门氏菌持久性的数据可有助于参与昆虫类食品安全性评估的风险评估人员和决策者进行进一步分析，从而有助于确定供应链中的卫生要求和风险缓解措施。该综述方案已在PROSPERO数据库（CRD42022329213）中注册。
