Abstract
Gastrointestinal infections are known to occur due to bacterial contamination of dairy products. A total of 141 dairy products viz. kulfi, ice cream and softy samples were investigated bacteriologically. Staphylococcus was the predominant organism isolated followed by Klebsiella pneumoniae, Escherichia coli and Campylobacter. Two of the samples also yielded Yersinia. The total bacterial counts obtained ranged from 2 x 10(1) to 5.2 x 10(11) colony forming units per ml (CFU/ml) for kulfi, 4 x 10(1) to 9 x 10(9) CFU/ml for ice cream and 2 x 10(1) to 2 x 10(10) CFU/ml for softy samples. The high degree of bacterial contamination seen indicates poor hygienic conditions and faults in manufacturing/handling of dairy products during and after processing and production.
