Retrospective validation of whole genome sequencing-enhanced surveillance of listeriosis in Europe, 2010 to 2015.

Conclusions: These findings provide a good basis for comprehensive EU/EEA-wide, WGS-enhanced surveillance of listeriosis. Time limits should not be used for hypothesis generation during outbreak investigations, but should be for analytical studies. PMID: 30131096 [PubMed - in process]

koh Disease outbreaks caused by the ingestion of contaminated vegetables and fruits pose a significant problem to human health. The sources of contamination of these food products at the preharvest level of agricultural production, most importantly, agricultural soil and irrigation water, serve as potential reservoirs of some clinically significant foodborne pathogenic bacteria. These clinically important bacteria include: Klebsiella spp., Salmonella spp., Citrobacter spp., Shigella spp., Enterobacter spp., Listeria monocytogenes and pathogenic E. coli (and E. coli O157:H7) all of which have the potential to cause dise...

This study evaluated efficacies of four commonly used chemical sanitizers at practical concentrations against L. monocytogenes biofilms on major food-contact surfaces including stainless steel, low-density polyethylene (LDPE), polyvinyl chloride (PVC), polyester (PET), and rubber. In general, efficacies against L. monocytogenes biofilms were enhanced by increasing concentrations of quaternary ammonium compound (QAC), chlorine, and chlorine dioxide, or extending treating time from 1 to 5 min. The 5-min treatments of 400 ppm QAC, 5.0 ppm chlorine dioxide, and 200 ppm chlorine reduced 3.0–3.7, 2.4–2.7, and 2.6&nda...

(BfR Federal Institute for Risk Assessment) To make food even safer for humans, experts from scientific institutions, food regulatory authorities and the business community will discuss current developments and strategies at the 'Zoonoses and Food Safety' Symposium at the German Federal Institute for Risk Assessment (BfR) on 4 and 5 November 2019, in Berlin-Marienfelde. Because some micro-organisms in food can cause health problems. Campylobacter in raw milk, salmonella in eggs or listeria in ready-to-eat foods often lead to outbreaks affecting numerous patients.

Publication date: Available online 22 October 2019Source: Journal of Food EngineeringAuthor(s): Jiyoon Yi, Kang Huang, Glenn M. Young, Nitin NitinAbstractCross-contamination of fresh produce during postharvest processing could be a significant risk factor that can lead to foodborne outbreaks. The aim of this study was to simulate cross-contamination from a contaminated lettuce to non-contaminated leaves/abiotic surfaces (glass, polyethylene), quantify the bacterial transfer efficiency to determine the influences of contact time, number of repeated contacts, and applied contact force, and evaluate the influences of surface ...

Publication date: Available online 12 September 2019Source: Microbial PathogenesisAuthor(s): Rokhsareh Mohammadzadeh, Azadeh Azadegan, Behrooz Sadeghi KalaniAbstractListeriosis is a serious infection linked to the consumption of food contaminated with Listeria monocytogenes. Outbreaks and mortality rates associated with this infection make it a significant public health concern. As biocontrol agents, probiotics such as Lactobacillus plantarum had been of interest for the promotion of antilisterial activities. However, a recent bacteriocin from epidemic L. monocytogenes strains called listeriolysin S (LLS) has been identifi...
