The present investigation was undertaken to estimate the microbiological quality of marketed foods of animal origin in the city of Kolkata. A total 300 various categories of food samples comprising of retail raw beef (n=75), goat meat (n=75), chicken (n=75) and unpasteurized poultry eggs (n=75) were collected from different open domestic market of Kolkata. The aerobic bacterial contamination load were estimated in retail raw beef ranging from 1.2x105 to 4.1x107 cfu/g, goat meat 2.9x105 to 5.3x106 cfu/g, chicken 3.3x104 to 5x106 cfu/g and unpasteurized eggs <1 to 2.1x107 cfu/ml. The fecal Escherichia coli (Coliform) was detected in 41 of 75(54.66%) raw beef, 47 of 75 (62.66%) goat meat, 53 of 75(70.66%) chicken and 3 of 75(04.00%) unpasteurized poultry eggs. These findings indicate substantial presence of microbial contaminants in foods of animal origin in open markets of Kolkata, where dearth of proper sanitation in the market places prevails.
