Title

Microbiological quality of ice cream from Warsaw market

Abstract

The target of present research was opinion of microbiological quality of ice creams in Warsaw market in aspect of requirements of the Polish Standard for the ice cream (PN-99/A-86431) and the Regulation of the Minister of Agriculture and Rural Development. A total of 87 samples of ice creams were analysed for standard plate count and coliform count. The results show that total bacterial count was considerably (in 97,7% of samples) below the limits of the Polish Standard (m = 5×104; M = 2,5×105 cfu/g) and of the Regulation of the Minister of Agriculture and Rural Development (m = 1×105; M = 5×10cfu/g). 86% of the samples had a coliform count lower than 10 cfu/g. In refer to requirements of Polish Standard for coliform number in ice cream (m = 102M= 103 cfu/g), 6 samples failed to meet the requirements of the m value for coliform bacteria, and additionally 1 sample – M value for coliform bacteria. The Regulation of the Minister of Agriculture and Rural Development quote sharpens requirements for coliform bacteria (m = 10; M = 100 cfu/g). According to this criteria, excess of the m value were noted down in 10 samples of ice creams.
