[Microbiological characteristics and detection of capsular forms of bacteria of the intestinal group in confectionery produced at the candy-chocolate factories].
Five types of confectionery and its semifinished products were investigated for contamination with Klebsiella, mesophilic aerobic and elective anaerobic, coliform bacteria, E. coli, etc. after a long-term storage. E. coli and St. aureus were not detected after inoculation on 1 g of the product; mold fungi were identified only in singular samples, their level did not exceed 20 CFU/g; the level of mesophilic aerobic and elective anaerobic bacteria varied from several hundreds to 3000-5500 CFU/g; coliform bacteria were identified in the amounts from 11 to 100 CFU/g. The identification of coliform bacteria has evidenced the presence of Enterobacter aerogenes and Kl. pneumoniae in the products investigated. Klebsiella were detected in 28-30% of the samples analyzed, their level did not exceed 100 CFU/g. The authors have proved the necessity of microbiological control of starting material, semifinished and finished confectionery products for the above bacteria.
