In Japan, the foods which are most frequently involved in staphylococcal food poisoning are sushi (raw fish ) and lunch-box meals that contain multi-ingredient foods (16,17). In Italy, S. aureus was mainly detected in meat products (2). The major foods involved in outbreaks in Korea from 1996 to 2000 were meat, raw and undercooked sea food, multi-ingredient foods, and lunch-box meals (11). Monitoring RTE (ready to eat) food contamination by S. aureus in Korea, it was found that 19.8% of the raw fish was contaminated with S. aureus.( 20,21). Obviously, contamination of ready to eat foods in fishery products has been less than ever.
