Description
Summary:Ten samples of baby foods comprising seven brands of infant milk foods and three brands of milk-cereal weaning foods were examined for incidence of different types of microorganisms. One brand of infant milk food with 91 × 10 organisms also exhibited the maximum number of staphylococci and some of these were coagulase positive. Some staphylococcal isolates showed thermostable deoxyribonuclease (DNase) activity and also produced enterotoxins A or B. One sample of weaning food showed high counts of Bacillus cereus . In one of the reconstituted baby food samples when held at ambient temp. (37.5 C), the Staphylococcus aureus and B. cereus counts increased 10-fold in 3 h.
