Abstract

The present investigation pertains to the starch adulteration of raw milk and milk products and to study the bio typing of Bacillus cereus emetic strain isolated from raw milk and milk products in Kashmir valley. The study was conducted during October 2009-June 2010. A total of 175 samples comprising of 50 raw milk and 125 of different milk products (25 each of burfi, rasgulla, rasmalai, ice-cream and cheese/paneer) were tested. Starch/rice flour was detected in 7, 6, 5, 4, 3 and 2 samples of raw milk, rasgulla, burfi, ice-cream, rasmalai and cheese/paneer samples, respectively. Bacillus cereus emetic strains were isolated from 8 of the raw milk and 20 of the milk products samples, (6, 5, 4, 3 and 2 samples out of 25 each of rasgulla, burfi, ice-cream, rasmalai and cheese/paneer, respectively). B. cereus emetic strains were isolated from 16 percent of the raw milk. Raw milk, burfi and ice-cream revealed biotypes 2, 5 and 7, whereas, rasmalai and cheese/paneer revealed only biotype 5. Biotypes 2 and 5 were recovered from rasgulla.
