摘要

食源性疾病是一个重大的公共卫生问题,涉及集体健康和经济,对医疗成本和农业企业都有影响。本文介绍了 2022 年在马尔凯大区(意大利)发生的一起肠炎沙门氏菌亚种食源性疫情的调查情况和结果,该疫情与食用烤猪肉产品(porchetta)有关。作为本文讨论的疫情调查的一部分,我们进行了分子分析,以评估临床、食物和环境来源菌株之间的基因组相关性。所有不同来源的沙门氏菌菌株都被血清分型为具有抗生素耐药性模式和等位基因特征的单相鼠伤寒沙门氏菌变种,从而确定了 "群集菌株",并通过全基因组测序分析明确证实了临床和食物/环境来源菌株之间的相关性。根据实验室证据,当地动物性食品卫生服务机构在猪肉加工厂和相关零售店采取了纠正措施。这项研究的结果表明,只有保证高效的数据交换、标准化的程序和人员培训,才能进行有效的干预。后一个方面也与食品企业经营者有关,他们必须采取适当措施将风险降至最低。

Monophasic variant of Salmonella Typhimurium 4,[5],12:i:- outbreak: an investigation by the Competent Authority
Foodborne diseases represent a significant public health issue, regarding both collective health and the economy, with implications for healthcare costs and agribusiness. This paper shows the description and results of the investigation of a Salmonella enterica subsp. enterica foodborne outbreak that occurred in the Marche Region (Italy) in 2022, linked to the consumption of a roasted pork product (porchetta). As part of the outbreak investigations discussed in this article, molecular analysis to evaluate the genomic correlation between clinical, food, and environmental origin strains was carried out. All Salmonella strains of different origins were serotyped as monophasic variants of Salmonella Typhimurium with an antibiotic-resistance pattern and an allelic profile such as to define the "cluster strain" allowing the correlation between clinical and food/environmental strains, definitively confirmed by whole genome sequencing analysis. Following the laboratory evidence, corrective measures at the porchetta processing plant and at the retail stores involved were carried out by the Local Animal Based Food Hygiene Service. The results of this study show that effective intervention is only possible if efficient data exchange, standardized procedures, and staff training are guaranteed. The latter aspect also concerns the food business operator, who must take appropriate measures to minimize the risk.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
