| In recent years, with incidents of food safety hazards continue to occur, food safety more and more attention due to consumption of contaminated bivalve shellfish pathogens of foodborne diseases caused by frequent contamination of bivalve shellfish microbial pathogens quantitative risk assessment was almost empty, short-necked clam (Ruditapes philippinarum)was the one. Based on the recent domestic and international microbiological risk assessment of aquatic products to explore the basic situation of short-necked clam in foodborne disease pathogens Vibrio parahaemolyticus in particular for the qualitative and quantitative microbiological risk assessment, while noting that the existing lack of evaluation system and the future direction and measures need to be perfected.In this study, to assess the Clam Vibrio parahaemolyticus in providing a principled framework for data and information; but also for other Vibrio parahaemolyticus in foods quantitative risk assessment provides a reference. However, the risk assessment was a need to constantly improve the discipline, the lack of data in quantitative risk assessment of microorganisms, there were still many deficiencies, many models were still many uncertainties. This requires in the future course of the study, close contact with relevant multi-disciplinary, regularly added and updated materials to reduce the uncertainty in existing models to improve risk assessment system. Risk assessment results were used to establish the exposure assessment and dose-response model of the data and assumptions, with increasingly improved epidemiological surveillance data, you can eliminate the uncertainty in the assessment process, and provides reference.For Consumers should have a correct understanding of active food safety risk assessment, we know that"zero risk"of food is non-existent, the purpose of risk assessment was to establish a more comprehensive risk management system, effectively reduce due to infection Resulting from microbial hazards, risk areas would be controlled at an acceptable level. The results were as follows:(1) By studying the consumption of aquatic products wholesale market to the supermarket chain of this density of Vibrio parahaemolyticus in the dynamic changes, the establishment of short-necked clam during storage the growth of Vibrio parahaemolyticus in the dynamic model, the assumption of known supermarket Clam density of Vibrio parahaemolyticus circumstances, the use of Monte Carlo simulation to predict the retail stage Clam contained in the density of cases of Vibrio parahaemolyticus. Meanwhile, the detection of short-necked clam collected at retail outlets in the density of Vibrio parahaemolyticus, and to compare the results with the prediction analysis to determine the accuracy of the model. Through surveys of consumer consumption patterns and consumption, and consumption of grilled and fried risk of infection with Vibrio parahaemolyticus caused the situation, model: Y = (1 36.88765+30032.6654×X)-0.268921.(2) The forecast Clam retail outlets in the probability density of Vibrio parahaemolyticus and consumption, the dose - response curve of the combination of predicted consumption per capita per year due to illnesses caused by raw Clam average of 1.65E-8, the average meal suffering Disease risk 4.55E-8 (approximately 455,000,000 people per year who have a disease), while assessment of risk in different seasons.
