OBJECTIVE
To investigate the contamination status of infants and young children foods by Bacillus cereus.
METHODS
1716 food samples were collected from retail market in 8 provinces in China and examined for Bacillus cereus by the plate count method.
RESULTS
Bacillus cereus was isolated from 9.85% of all the samples (169/1716). 14.08% of the powered formula for infants and young children were contaminated with B. cereus as well as 6.01% of the ready-to-eat cereal-based complementary foods for infants and young children. Counts higher than 100 CFU/g were found in 18 samples of the powered formula (2.20%) and 10 samples of the ready-to-eat cereal-based complementary foods (1.11%).
CONCLUSION
Inspection and management of infants and young children foods should be enhanced to prevent Bacillus cereus infection.
目的
调查婴幼儿食品中蜡样芽孢杆菌的污染状况。
方法
从中国8个省份的零售市场采集1716份食品样本，采用平板计数法检测蜡样芽孢杆菌。
结果
所有样本中有9.85%（169/1716）检出蜡样芽孢杆菌。14.08%的婴幼儿配方奶粉以及6.01%的即食婴幼儿谷物类辅食被蜡样芽孢杆菌污染。在18份婴幼儿配方奶粉样本（2.20%）和10份即食婴幼儿谷物类辅食样本（1.11%）中发现菌落数高于100 CFU/g。
结论
应加强对婴幼儿食品的检验与管理，以预防蜡样芽孢杆菌感染。
