背景:由沙门氏菌引起的胃肠炎爆发,希腊人类分离株中很少发现的血清型,发生在希腊南部农村地区宗教节日的参与者中,2022年9月。这项研究的目的是描述疫情的流行病学方面,确定食源性病原体的传播媒介并建议预防措施。
方法:爆发与食用街头食品摊贩提供的当地传统烤猪肉食谱有关。2018年,同样的食物,在同一地区的餐厅供应,与另一起S.Give爆发有牵连。
结果:疫情调查显示,与疫情相关的分离株,食物和人类起源,属于同一个S。给菌株。确定了有关食品安全实践的重大缺陷。
结论:有关病原体传播途径的技术知识对于食品处理者和消费者遵循卫生和卫生措施非常重要,主要是在大规模集会的情况下,在那里准备了大量的食物,处理,煮熟和服务。高效的官方监督,主要是在夏季节日,是为了避免由病原体/食品的不同组合引起的食源性感染的复发。
BACKGROUND: An outbreak of gastroenteritis due to Salmonella Give, a very rarely identified serotype in human isolates in Greece, occurred in participants of a religious festival in a rural area of southern Greece, in September 2022. The objectives of this study were to describe the outbreak in terms of epidemiology, identify the vehicle of transmission of the foodborne pathogen and recommend prevention measures.
METHODS: The outbreak was linked to the consumption of a local traditional recipe of roasted pork meat served by a street food vendor. In 2018, the same food item, served in a restaurant in the same region, was implicated in another S. Give outbreak.
RESULTS: Outbreak investigations revealed that outbreak-associated isolates, of food and human origin, belonged to the same S. Give strain. Significant deficiencies regarding food safety practices were identified.
CONCLUSIONS: Technical knowledge about pathogen transmission paths is important in order for both food handlers and consumers to follow hygiene and sanitary measures, mainly in cases of mass gatherings, where large quantities of food are prepared, handled, cooked and served. Efficient official supervision, mainly during summer festivals, is required in order to avoid recurrence of foodborne infections by different combinations of pathogens/food commodities.
