Food-borne diseases associated with the consumption of poultry meat and its processed products are of public health concern worldwide. An investigation was conducted to assess the bacteriological quality of poultry meat from some poultry farms and its health impact on consumer of Nalitabari paurosova, Sherpur district, Bangladesh. Total 15 samples were randomly selected and collected from different poultry farms on the basis of farms level and size. Bacteriological quality of the samples was assessed by following the standard microbiological methods. The health impact was evaluated with the help of semi-structured based questionnaire of 400 peoples. The average value of TVC and TCC were found as 4.3 × 106 CFU/g and 3.6 × 104 CFU/g respectively. In this study, the prevalence of fecal coliform was recorded as 33% and the presence of E. coli in 53% samples. The mean value of Salmonella spp. of meat samples was 4.6 × 103 CFU/g. No Shigella spp., Vibrio spp. and fungal species were detected in any sample. Some selected isolates were tested for their sensitivity against some commercially available common antibiotics used in Bangladesh. E. coli was 80% resistance to Ampicillin and 90% sensitive to Ciprofloxacin whereas Salmonella spp. showed 100% resistance to Ampicillin and 80% sensitivity to Ciprofloxacin. The antibacterial activity of renowned medicinal plant Azadirachta indica was also evaluated against some multidrug resistance bacteria. The inhibitory zone of both 30% methanolic and ethanolic extracts of Azadirachta indica was 12 mm and 12.3 mm, where 40% methanolic and ethanolic extracts were 14 mm and 16.3 mm against E. coli. The 40% ethanolic extract showed the better activity between them. The plant extract has no activity against Salmonella spp.. Awareness and health impact of broiler meat was determined among the people of different sectors on the basis of educational qualification, socio-economic condition, income source, broiler meat intake pattern, BMI range and food related diseases they have suffered. The peoples who eat broiler meat are much more prone to complicated diseases than the peoples who never eat it. So broiler meat intake pattern must be changed for better health. The widespread occurrence of Salmonella spp. and E. coli in poultry meat also reinforces the need for effective control measures.展开更多

The present work deals with the assessment of physicochemical and bacteriological profile of several pond, jar and tube-well water samples to ensure its suitability for using and drinking. Total 30 samples were randomly selected and collected from Nakla Paurosova of Sherpur district by following the standard procedure. Bacteriological analysis was carried out by following the standard bacteriological methods. Most of the surface water sampling points were polluted by dumping of waste, cattle wash and were not suitable for drinking or other domestic purposes. Among three heavy metals, only Iron was detected in six tube-well water samples, one was also positive to arsenic, rest of the water bodies were negative to all of these metals. In case of most of the water bodies, different physicochemical properties were below standard limit. In pond water, the Total Viable Count (TVC) ranged from 2.7 × 107 cfu/100ml to 4.4 × 1015 cfu/100ml and Total Coliform Count (TCC) were 3.4 × 105 cfu/100ml to 4.8 × 1013 cfu/100ml, where the mean concentration of Heterotrophic Plate Count (HPC) was 2.4 × 105 cfu/100ml and 1.8 × 105 cfu/100ml in jar and tube-well water respectively. On the other hand, the Total Coliform Count of supply water was 33 cfu/100ml and tube-well water was 14 cfu/100ml. Fecal coliform was detected in all of the pond water samples, four jar and three tube-well water too. E. coli was present in all pond water samples, and also detected in 80% supply and 50% tube-well water also. Shigella spp. was found in two pond water and in one supply water, where tube-well water was free from it. Salmonella spp. was also detected in 30% of pond and 20% of supply water, whereas absent in tube-well water. 50% of pond, 40% of supply and 30% of tube-well water were contaminated with Vibrio spp. The total counts of these pathogenic bacteria exceeded the acceptable limit both surface and drinking water and also showed resistance against a broad range of commercially available antibiotics. Survey-based result revealed that, peoples of the study area who were using or drinking these water, were suffering from various water borne diseases. These kinds of water sources pose a major threat to public health. So, public awareness, proper treatment and precise management are needed prior to use and drink of these water.展开更多
