A cross‐sectional study of raw meat samples from the local meat market of Kathmandu Metropolitan City was carried out during September 2002 to May 2003 with special emphasis on isolation and identification of Salmonella bacteria. A total of 123 raw meat samples (55 chicken, 37 buffalo, and 31 goat) were collected and analyzed relative to season. Salmonella spp was found in 11.4% (14/123) meat samples. Eight samples of chicken, that is, 14.5%, five samples of buffalo (13.5%), and one sample of goat (3.3%) were found to be positive for Salmonella . Salmonella prevalence revealed Salmonella (S.) pullorum in 3.3% samples , S. gallinarum in 0.8%, S. typhi in 1.6%, S . choleraesuis in 0.8%, and Salmonella of subgenus I or II group in 4.9% samples. More than 80% meat samples microbiologically processed indicated coliform contamination. Seasonal prevalence of Salmonella was highest in the months of April/May. Surveys revealed unsatisfactory conditions of sanitation in the local meat markets of Kathmandu.
