To investigate the contamination of food borne pathogens in foods for infants and young children in Guangxi markets, and provide reference for the prevention of food borne disease and the food safety alert.Methods Foods were collected from department stores, supermarkets, wholesale markets and convenient stores in 14 areas of Guangxi. The samples were detected for Bacillus cereus, Enterobacter sakazakii and Staphylococcus aureus according to the national standard methods.Results ①A total of 1 939 samples were detected. The total detecting rate was 13.56% (263/1 939). The detecting rate of Enterobacter sakazakii was 3.15%, and cereal-based complementary foods (4.19%) was significantly higher than the infant and toddler formulas (0.83%,χ²=15.361,P<0.05). The detection rate of Bacillus cereus was 10.37%, and infant and toddler formulas (14.12%) was significantly higher than the cereal-based complementary foods (8.68%,χ²=13.238,P<0.05). The detection rate of Staphylococcus aureus was 0.05%. ②Quantitative results:among the 61 positive samples of Enterobacter sakazakii, 43 samples were below 5 MPN/100 g, 3 samples were above 110 MPN/100 g, the maximum value was 240 MPN/100 g. Among 201 positive samples of Bacillus cereus, 159 samples were below 100 MPN/g, 10 samples were above 100 MPN/g, and the maximum value was 1 100 MPN/g though the MPN method. 19 samples were below 100 cfu/g, 13 samples were above 100 cfu/g, and the maximum value was 4×10⁷ cfu/g though the plate method. ③The detecting rate of Bacillus cereus and Enterobacter sakazakii in cereal food for different ages ranged from 5.69% to 21.05% and 3.45% to 5.26%. ④The detection rate of pathogenic bacteria in foods for infants and young children from different place of production ranged from 8.84% to 23.47%.Conclusion The contamination of Bacillus cereus and Enterobacter sakazakii existed in market foods for infants and young children in Guangxi. The enterprise should strengthen the production process supervision to guarantee the safety of foods for infants and young children.
