The present research work was undertaken to assess the bacterial quality and to know the prevalence of zoonotic bacteria from broiler meat samples sold in Krishi market, Bihari camp market, Agargaon market, Taltola market and SAU (Sher-e-Bangla Agricultural University) mini bazar, Dhaka, Bangladesh from January to May 2018. After processing of samples primary culture was done in nutrient broth and nutrient agar media then pure culture was obtained from different selective media. Total Viable Count (TVC), Total Coliform Count (TCC) and Total Salmonella Count (TSC) in broiler meat of different broiler markets were determined. Mean of TVC, TCC and TSC for the Krishi market, Agargoan market, Taltola market, Bihari camp market and SAU Mini market were 5.67, 4.32, 2.96 log10 CFU/g, 5.88, 4.64, 3.56 log10 CFU/g, 6.10, 4.68, 3.78 log10 CFU/g, 6.68,4.87, 3.84 log10 CFU/g and 5.84, 4.25, 3.13 log10 CFU/g respectively. The prevalence of Escherichia coli and Salmonella spp. Were 74% and 42% respectively. E. coli isolates were showed sensitive to Ciprofloxacin (91.6%), Gentamycin (87.5%), Azithromycin (66.66%), and Tetracycline (58%) and resistant to Penicillin (79.16%) then Amoxycillin (75%), Streptomycin (75%) and Ampicillin (58.3%). Highest resistant pattern was showed by Tetracycline (58%), Streptomycin (72.72%), Penicillin (72.72%) and Amoxycillin (63.63%). Highest resistant pattern showed by Amoxycillin (71.42%) and Penicillin (71.42%). This study revealed that broiler meat sold at some local markets of Dhaka city were contaminated with multiple species of multidrug resistant bacteria which may risk for human health. Res.

The aim of this study was to investigate the nutritional and microbial quality of yoghurt from different districts of Bangladesh. Protein content was higher (4.56g/kg) in SB2 (sample Bogura-2), fat content was also higher (5.67g/kg) in SB3 (sample Bogura-3). The acidity found ranged from 0.77% to 0.98%, pH obtained ranged between 3.6 to 4.98 and total solid retained between 23.08 to 26.95 for all samples. Highest Total Viable count (TVC) value was found in SB2 (68.9×104±0.23 CFU/ml) and lowest value was observed in SJ2 (23.01×104±0.43 CFU/ml). No mold and yeast were found in the collected samples during study period that indicates all are follow hygiene procedure but all of the yogurt samples were contaminated with fewer amount (5.6±0.66 to 12.56±0.44 CFU/ml) of coliform. The mean value of acceptability score of yogurt sample was higher (99.2) in SB2 (sample Bogura-2) during the study period. Organoleptically, the overall quality of all yogurt samples was good. Considering the pH, acidity, total solids, protein, fat, carbohydrate and ash values for all yogurt samples collected from Bogura had better quality as compared to other samples. From the present study, it was found that all of the samples collected from Bogura district were much better quality compared to other samples in terms of nutritional, biochemical and microbial aspect. All of the samples were found in contaminated with lower amount of coliform so necessary actions should be taken in every step of processing, maturing and marketing to overcome this problem.
