Pathogens-in-Foods Database: A Web Application for Assessing the Occurrence Data of Microbiological Hazards in Foods Marketed in Europe

Abstract

Pathogens-in-Foods (PIF) is a dynamic database constructed using systematic literature searches of occurrence data (prevalence and enumeration) of important pathogenic agents (Bacillus cereus, Campylobacter spp., Clostridium perfringens, Listeria monocytogenes, Salmonella spp., Shiga toxin-producing Escherichia coli, Staphylococcus aureus, Yersinia enterocolitica, Cryptosporidium spp., Giardia spp., Toxoplasma gondii, Hepatitis A virus, Hepatitis E virus and Norovirus) in foods randomly surveyed across Europe. After filtering the primary studies, these were screened for relevance and methodological quality, and the data were extracted into the PIF database following a systematic categorisation of microbiological methods, food types and outcomes. The database is freely accessible through a web application that facilitates data retrieval according to several relevant variables. The PIF spans data published from 2000 onwards and is intended for use by researchers and food authorities after meta-analysis, in microbiological risk assessment.
