초록

본 연구에서는 인터넷에서 판매되는 배달이유식의 위생안전성을 평가하고, B. cereus의 독소유전자 분포를 파악하여 즉석조리식품으로 구분되는 이유식의 B. cereus 기준설정을 위한 기초자료를 제공하고자 하였다. 기타 영 유아식 27건, 즉석조리식품 79건 등 총 106건에 대한 실험결과는 다음과 같다. 1. 이유식 106건의 세균수 검사결과 기타 영 유아식에서는 12건(44%)에서 최대 $2.5{\times}10^3CFU/g$, 즉석조리식품에서는 46건(58%)에서 최대 $1.1{\times}10^6CFU/g$으로 대체적으로 즉석조리식품에서 세균수가 많이 검출되었다. 2. 106건의 검체 중 총 9건에서 B. cereus가 $10{\sim}3.6{\times}10^3CFU/g$ 범위로 검출되었으며 모두 즉석조리식품이었다. 3. B. cereus의 독소유전자 중 cytK는 6주(66.6%), nheA 및 entFM은 8주(88.9%), bceT는 7주(77.8%), hblC는 3주(33.3%)에서 검출되었으며 구토독소인 cer은 2주(22.2%)에서만 증폭밴드가 나타났다. 4. 분리된 균주는 B. cereus와 B. thuringiensis를 구분하기 위한 시험법에서 모두 B. cereus로 나타났다.

Bacillus cereus is food poisoning bacteria frequently occured in starch food. Most of the delivery foods for infant is classified as ready-to-cook food. But unlike food for infant and young children, there are no standards and specifications of Bacillus cereus in ready-to-cook food. The purpose of this study is to examine the presence of Bacillus cereus, aerobic bacteria and coliforms in the food for infant and young children sold through internet. B. cereus was detected in 9 samples (8.3%), total aerobic bacteria was detected over $10^6CFU/g$ in 4 samples and coliforms were not detected in any samples. This will provide basic data for standards and specifications of Bacillus cereus in ready-to-cook food.
