Basic research for the control of Campylobacter food poisoning

: Appropriate handling and controlled temperature prevent cross-contamination and proliferation of contaminants in foods, thereby reducing the incidences of food-borne gastroenteritis in Japan. However, the incidence of Campylobacter jejuni/coli infection did not markedly decrease and has become one of the major causes of food-borne diseases. C. jejuni and C. coli are widespread in warm-blooded domestic animals; therefore, food products may easily become contaminated during processing. C. jejuni and C. coli do not proliferate in foods, nor resistant to freezing, drying and oxidative stresses, and the number is greatly reduced under such conditions. These properties should be considered for risk management of Campylobacter in food processing and manufacturing.
