Research Summary :
The amount of exported/imported food is increasing year by year and it is a global activity. It is therefore an issue of a global importance to secure the necessary amount and safety of food traded. WHO and FAO are collaborating in establishing appropriate world standard levels of food-poisoning microbial pathogens in selected foods based on the results of risk assessment to avoid unnecessary trade friction. Sensitive quantitative detection methods are necessary for this purpose. In addition, the methods have to be easy to perform so that they can be carried out in all countries in the world including developing countries. The principal investigators and his collaborators have been studying international epidemiology of three food-poisoning bacterial enteric pathogens. They include Vibrio parahaemolyticus, enterohemorrhagic Eschericia coli O157, and toxigenic Vibrio cholerae. The foods contaminated by these pathogens are likely to become those need due attention when traded across international borders. In this study, unique techniques are employed to develop the above-mentioned detection methods and the newly developed methods will be subject to validations in various parts of the world.
