AbstractPresent study was carried out to find reduction in the level of Salmonella contamination in meat form public health point of view. Reduction in load of Salmonella on cattle body coats (hides) and in carcasses against the use of various washing treatments of the animals before slaughtering e.g. cleaning with; i. water, ii. Water plus soap iii. Water plus soap plus Dettol, iv. No washing (control). These treatments were applied on the cattle body coats of live cattle prior to slaughter, concurrently in following three groups i. fresh water, ii. 50 0C heated water and iii. 70 0C heated water. Samples were also collected after slaughtering from these groups which were treated against different treatments. In second part of the experiment, meat transporting vehicles were also washed to check the reduction in Salmonella prevalence. Total samples (n= 88) comprised of washed samples (n= 59) and unwashed (n=29). Data was transformed into log (LNTVC) for clearer understanding. All collected samples were positive for Salmonella contamination. A large number of colonies were observed and recorded as total viable count (TVC). Salmonella on the surface of unwashed (controlled) live animal coat (26.07 0.03) was significantly (P <0.01) higher (24%) than Salmonella in carcasses (21.26 0.04). Samples of treatment i.e. water plus soap plus Dettol showed highest 65% reduction in the level of Salmonella against group which used 70 0C heated water during washing of animal body coat respectively. Similarly level of Salmonella in carcasses reduced maximum in the group washed with 70 0C heated water. Mean Salmonella contamination on body coat decreased as samples moved controlled animals body coat (unwashed) to soap washed and soap plus Dettol wash 26.07 0.03, 20.780.03, 13.37 0.11 and 10.490.13 respectively. It is concluded that the washing with water, soap and Dettol at 70 0C Heat Water has significantly lesser load of salmonella. However the sanitizer application did not completely vanish the salmonella in the carcasses. This suggested that abattoir management at Peshawar should focus on the improvement of hygiene in all aspect of slaughterhouse
