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, which was 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 variant 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., Competing Interests: Conflict of interest: the authors declare no potential conflict of interest., (Copyright © 2024, the Author(s).)
