title: [Microbiological quality of muesli samples purchased in retail network].
abstract: The estimation of microbiological quality of muesli samples was the aim of this investigation. The study included 40 samples which represented various consignments of muesli, produced in 2002 year. Total number of aerobic mesophilic bacteria, yeasts and moulds, and also occurrence of pathogenic bacteria, coliforms and enterococci were determined. The systematic units of muesli fungal flora have been identified. It was stated that microbiological quality of all tested muesli was good. No pathogenic bacteria (Salmonella, Staphylococcus aureus and Bacillus cereus) was detected and also coliforms and enterococci titre was correct (> 0.1 g). A majority of samples characterized low contamination levels of mesophilic aerobic bacteria and fungi, and their total number did not exceed, suitably 10(3) and 10(2) cfu/g. The mesophilic aerobic bacteria were mainly represented by vegetative forms. The average share of these bacteria spores in total number of bacteria received 30%. The Aspergillus sp. and Penicillium sp. were regular elements of muesli fungal flora.
