Food Microbiology and Hygiene


The laboratory of Food Microbiology and Hygiene conducts basic and applied research projects on food-borne or waterborne pathogens that cause infectious diseases or food poisoning impacting on human health and food safety using food hygienic, microbiological and genetic approaches.

1) Ecology of foodborne bacterial pathogens in environments; microbial control using hurdle technology in foods; antibacterial activity of plant-extracts and its use in food preservation (Nakano, H.)

2) Pathogenicity, antimicrobial resistance and retron reverse transcriptases in foodborne pathogens; detection and disinfection of norovirus (Shimamoto, T.)
