Total viable bacterial count (TVBC) was determined on nutrient agar and for the isolation of specific microorganisms different selective media were used. Crude, ethanol, methanol, hot water and cold water extracts of the samples were prepared for analysing their antibacterial activity using the agar well diffusion method. Furthermore, the minimum inhibitory concentration (MIC) of the crude extracts was determined. TVBC was found between 10<sup>4</sup> to 10<sup>6</sup> cfu/g. None of these samples showed the presence of fungus. <em>Staphylococcus </em>spp. was present almost in all the samples between 10<sup>4</sup> to 10<sup>6</sup> cfu/g while <em>Bacillus </em>spp. was noticed only in one sample. <em>In vitro </em>antibacterial activity of the crude, methanolic and ethanolic extracts of the samples was found to be effective mostly against <em>Escherichia coli, Klebsiella </em>spp., <em>Listeria </em>spp., <em>Pseudomonas </em>spp. and <em>Bacillus </em>spp. On the contrary, hot water extracts of only two samples showed antibacterial property against <em>Pseudomonas </em>spp., <em>Listeria </em>spp. and <em>Klebsiella </em>spp. MIC was confirmed by using 96 well plate methods and the minimum inhibitory concentration was between 11.75 to 94 mg/ml.</p><p>Bangladesh J Microbiol, Volume 35 Number 1 June 2018, pp 1-5</p> ER -
