Until recently, members of the Cronobacter genus (formerly known as Enterobacter sakazakii) were a relatively unknown cause of human infections. Cronobacter spp. has since garnered significant attention as a major microbial contaminant of low moisture foods (LMFs). This study was conducted to survey the worldwide contamination of LMFs with Cronobacter spp. from 2002 to 2019 by using HorizonScan (an online surveillance tool) and to assess the prevalence of this pathogen in LMFs in the local food supply chain of Mauritius. LMF samples (n = 302) were collected from local retail outlets and subjected to microbiological analyses and molecular identification. HorizonScan recorded 31 notifications worldwide for LMFs contaminated with Cronobacter spp. Presumptive Cronobacter spp. were isolated from 35% of local LMF samples but were subsequently confirmed to be Pantoea dispersa. This report is the first for P. dispersa in LMFs in Mauritius, and this organism is considered an emerging opportunistic human pathogen. Wheat flour was identified as an important vehicle for P. dispersa with a contamination rate of 100%. Because LMFs are an integral part of the human diet and are consumed almost daily, these commodities should be monitored for P. dispersa.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
