A microbiological survey of contamination and microflora on Western-style undried confectioneries in the market was carried out and enterotoxin production by S. aureus strains isolated from them was investigated.
1. Viable counts in Western-style undried confectioneries in the mafket ranged from <102 to 107 CFU/g and 53% of all samples were contaminated with coliforms. The incidence of S. aureus and B. cereus were 16% and 27% of all samples, respectively.
2. Predominant microoflora found in the products were Leuconostoc, Micrococcus and yeast, being specific to each product.
3. Enterotoxin of S. aureus strains isolated from products of types B, C, A and AB was detected.
4. Growth and enterotoxin production of S. aureus inoculated in custard cream puff were observed at 25 and 35°C, but both were inhibited during the storage at 10°C for 72 hours.
