Microbial risk assessment (MRA) characterises and quantifies the likelihood of adverse human health effects associated with exposure to pathogenic microorganisms. Exposure assessment, which is a step of MRA, identifies potentially exposed populations and estimates the dose to which they are likely to be exposed. This paper focuses on the characterisation of human exposure to three species of Vibrio, representing nearly 75% of non-cholera Vibrio infections: Vibrio cholerae non-O1/non-O139, V. parahaemolyticus and V. vulnificus. Not enough data are available for cutaneous infections (wounds), but exposure assessment for ingestion route is possible. We review different types of information: virulence, type of shellfish or other seafood involved and their mean consumption, population sensitivity (normal or susceptible), initial concentration of pathogens in water or seafood, effect of storage in ambient air, and effects of refrigeration, freezing and cooking. Storage at ambient temperature is a key step in vibrio development, and neither freezing nor cooking are always sufficient to eliminate them. The risk develops during the steps between harvesting and consumption, and the most effective prevention measures must be taken then.
