The individual prevalence of BTB was 4.24% and 20.66% at ≥4 mm and ≥2mm cut off value respectively. The herd level prevalence of was found to be 48.9% (95%, CI: 34%-63%). The questionnaires survey results of this study indicated that, more than 85.1% of the households were consuming raw milk, whereas 14.8% were consuming heat-treated milk. 74.4% of the respondents were aware, that the transmission of bovine TB through consumption of raw milk, milk products and raw meat.
