Studies on the hygienic quality of ice-erearn consumed in elazığ and the correlation between the general colony counts and methylene blue reduction time

Abstract

The purpose of this study was to determine the hygienic quality of ıce-cream in Elazığ. 60 ıce-cream samples were examined. The average number of total viable aerob colony was found to be 1.6 x 107/g., Coliforms was 4.3 x 104/g., Staphylococcus was 8.7 x 104/g., Coagulase-positive Staphylococcus was 4.1 x 104/g., Faecal Streptococcus was 2.8 X 104/g ., yeasts and molds was 8.5 x 104/g. The correlation between the general viable colony count and the methylene blue reduction time was found to be significant ( p < 0.01 ). In conclusion, the hygienic qualities of the ıce-cream samples examined were low and didn't fit to the recommended microbiological standards.
