The aim of this research was microbiological valuation of the following frozen fruits: strawberries, raspberries, black and red currants, gooseberries and bilberries produced in cold storage plant in Lublin province. Analysis included: total count of mesophilic bacteria, number of yeasts and moulds, lactic and acetic bacteria, sporing anaerobes, coliforms, Enterobacteriaceae, Proteus spp., B. cereus, S. aureus and the presence of Salmonella spp. and Listeria spp. The highest total number of mesophilic bacteria, lactic bacteria and yeasts was observed in the samples of bilberries (10⁴– 10⁵ c.f.u./g) and the lowest count of mentioned microbes was obtained in the chilled gooseberries samples (10¹-10² c.f.u./g). The number of the moulds was the lowest in the strawberries (10¹/g) and the highest in black and red currants, bilberries and raspberries (10³/g). Coliforms, Proteus spp., S. aureus, Salmonella spp. and Listeria spp. were not found. Microbiological quality of analysed frozen fruits generally fulfils the polish and foreign requirements.
