Outline of Final Research Achievements	The Red and Mekong River delta in Vietnam are food production sites. The huge amounts of food are exported from these regions to many countries including Japan. However, food and water contamination by toxic chemicals are often observed by economic growth and inappropriate usage of pesticides and antimicrobial reagents. In this stud, we surveyed the actual situation of chemical contamination in food and environmental water collaborated with Vietnamese institutes. We observed contamination with arsenicum and cadmium in rural area in Thai Binh and Nam Dinh province in the Red River delta. The contaminations with antimicrobial reagents in aquaculture water were found around Can Tho city, in the Mekong Delta. The correlation between the contaminations and resistance of microbial isolates from cultivated fishes collected from same sites was observed.
