  • About the Edition

    Vibrio vulnificus is one of three pathogenic Vibrio spp. on which FAO and WHO have undertaken risk assessment work. This pathogen is associated primarily with raw oysters but can occur in a variety of seafood products. As well as causing gastrointestinal illness, V. vulnificus can cause primary septicaemia which is a serious and often fatal disease in individuals with chronic pre-existing conditions. This volume provides an approach for undertaking quantitative risk assessment of V. vulnificus in raw oysters. This risk assessment model was also developed to evaluate the effectiveness of various interventions strategies aimed at reducing V. vulnificus levels in oysters and therefore the associated risk of illness.--Publisher"s description.

    Vibrio vulnificus presents a significant public health risk to certain persons consuming raw or undercooked seafood, or who acquire wound infections . Introduction. Vibrio vulnificus is a member of the Vibrionaceae family, whose pathogenic species include V. cholera, V. parahaemolyticus, and V. is from the Latin ‘to wiggle or vibrate’ and vulnificus from the Latin ‘to wound.’ The bacillus is found worldwide and can cause gastrointestinal disease, wound infections, and highly fatal septicemia.

    Postharvest growth of Vibrio vulnificus in oysters can increase risk of human infection. Unfortunately, limited information is available regarding V. vulnificus growth and survival patterns over a wide range of storage temperatures in oysters harvested from different estuaries and in different oyster species. In this study, we developed a predictive model for V. vulnificus growth . More Vibrio vulnificus animations & videos Prognosis for Vibrio vulnificus. Prognosis for Vibrio vulnificus: V. vulnificus infection is an acute illness, and those who recover should not expect any long-term consequences. (Source: excerpt from Vibrio vulnificus (General): DBMD). More about prognosis of Vibrio vulnificus. Research about Vibrio vulnificus.

    illness associated with the consumption of oysters, including the FAO/WHO Risk Assessment of Vibrio vulnificus in Raw Oysters (FAO/WHO, ), and transforming it into practical guidance that can be used by risk managers to elaborate potential risk management options. A beta Poisson dose-response model for Vibrio vulnificus food poisoning cases leading to septicemia was used when evaluating the effect of 15°C depuration on the estimated risk of raw oyster consumption. Statistical variability sources included V. vulnificus load at harvest, time and temperature during harvest and transportation to processing.
