During 2006, prevalence of Salmonella isolated from hand swabs of butchers in 5 fresh markets of Khon Kaen municipality was found at 37% and for rectal swabs was found at 31%.

Salmonella isolates from hand swabs resistant to amoxicillin, chloramphenicol, nalidicic acid, sulfamethoxazole/ trimethoprim, and tetracycline were 71%, 27%, 17%, 32%, and 66%, respectively. Isolates from rectal swabs resistant to amoxicillin, chloramphenicol, nalidixic acid, sulfamethoxazole/trimethoprim, and tetracycline were 81%, 22%, 28%, 50%, and 78%, respectively. All isolates were susceptible to ciprofloxacin. Salmonella isolates from pork which were resistant to amoxicillin, chloramphenicol, sulfamethoxazole/trimethoprim, and tetracycline were 68%, 39%, 75%, and 89%, respectively.
