Serotypes and antimicrobial resistance of salmonella enterica isolated from pork, chicken meat and lettuce, bangkok and central thailand.

In this study, 120 (40 pork, 40 chicken meat and 40 lettuce) samples were randomly collected from retail markets in Bangkok and central Thailand during June to August 2015 for Salmonella serotype identification and antimicrobial susceptibility testing. Salmonella was found in 82%, 62% and 20% of pork, chicken meat and lettuce samples, respectively. The top 5 most common Salmonella serotypes were Panama (15%), Schwarzengrund (12%), Rissen, Anatum, and Stanley (11% each), Albany (9%), and Indiana (8%). A high percentage of Salmonella isolated from food of animal origin were resistant to multiple antimicrobial drugs, including ampicillin, chloramphenicol, nalidixic acid, sulfamethoxazole-trimethoprim, and tetracycline. From antibiogram pattern analysis, the most common serotypes constituted isolates that were multidrug resistant. The study indicates that Salmonella was still present in various kinds of food and that certain serotypes have become predominant, a phenomenon not previously reported in Thailand.
