Popis: A study was conducted to assess the sanitary quality of ice cream manufactured by five different plants namely Milk vita, Igloo, Polar, Savoy and Kwality sold in retail stores in Mymensingh Town, Bangladesh. The result revealed the average total viable counts which were 3267 CFU/ml (log 3.5) in Milk vita, 3500 CFU/ml (log 3.5) in Igloo, 13833 CFU/ml (log 4.1) in Polar, 16500 CFU/ml (log 4.2) in Savoy and 20916 CFU/ml (log 4.3) in Kwality ice cream samples. It was found that the highest extent of microbial contamination and proliferation of viable bacteria occurred in Kwality ice cream. The average coliform counts obtained from the study was in milk vita 0.33 CFU/ml (log -0.5) and igloo 0.0 CFU/ml (log 0.0), Polar16500 CFU/ml (log 4.2), Savoy 16500 CFU/ml (log 4.2), Kwality 20916 CFU/ml (log 4.3) and the presence of numbers of coliforms in Polar, Savoy and Kwality ice creams samples were fairly high (10/ml) indicated the poor hygienic practices during manufacture, post process contamination and unsatisfactory transportation. Statistically the coliforms were found more closely related to total viable counts than the staphylococcal counts. The average staphylococcal counts as revealed in the samples of Milk vita, Igloo, Polar, Savoy and Kwality were 0.5 CFU/ml (log -0.3), 0.0 CFU/ml (log 0.0), 4.33 CFU/ml (log 0.6), 8.8 CFU/ml (log 0.9) and 4.4 CFU/ml (log 0.6) respectively may present cause for alarm which could be associated with potential food poisoning hazards. The results demonstrated that Igloo and Milk vita ice creams are of the superior quality product in respect of sanitary condition.
