The aim of the researches was to determine the microbio¬logical quality of different type of cheeses originated from ecological farms. 52 samples of cheeses were examined. The total number of bacteria ranged from 105 to 1010 in acid-curd cheeses (AC), 107-10n in ripened cheeses (RC) and 108-1011 CFU/g in acid-rennet cheeses (ARC). The number of contami¬nation bacteria varied between 103 and 107, 105-106 and 105¬109 CFU/g in AC, RC and ARC, respectively. Coliforms and E. coli in AC were present in 63% and 44% samples, in RC — in 53% and 53% samples, in ARC — in 59% and 35% samples, respectively. The number of psychrotrophic bacteria ranged from 101 to 106 CFU/g in the examined samples. The presence of B. cereus was detected in 8% of the examined samples. The number of yeasts and moulds ranged from 102 to 105 in AC, 101-106 in RC and 101-107 CFU/g in ARC.
