Abstract:
A cross-sectional study of different portions of chicken raw meat samples from the local meat markets of North East India was carried out during October 2007 to September 2008 on a total of 110 collected samples using Plate Count Agar, Lactose broth, Violet red bile glucose agar, Brilliant green bile lactose broth, Eosin methylene blue agar, MacConkey agar, Salmonella shigella agar, Bimuth sulphite agar, Xylose lysine deoxycholate agar, Nutrient agar and Potato dextrose agar. Of the 74 different bacteria detected, the bacterial population incidence was highest in chicken wings (83.5%), followed by chicken tails (77%), breasts (70%), thighs (69%) and gizzard (38%). Frequent organisms in the samples were Enterococcus faecalis (100%), Enterobacter aerogenes (100%), Escherichia coli (98%), Klebsiella pneumoniae (98%), Micrococcus sp. (69%) and Candida sp. (80%). The other organisms isolated were Klebsiella oxytoca (35%), Citrobacter sp. (52%), Proteus sp. (49%), Staphylococcus aureus (20%), Staphylococcus epidermidis (20%), Yersinia enterocolitica (23%), Listeria monocytogenes (15%), Shigella dysenteriae (1.8%), Salmonella tyhpi (20%), Bacillus cereus (10%), Aeromonas sp. (5.5%), Alcaligens faecalis (15%), Penicillium sp. (42%), Aspergillus sp. (20%) and Rhodotorula sp. (5.5%). This finding indicates substantial presence of microbial contaminants in retail chicken meat samples in North East India and dearth of proper sanitation in the market places. |
