Abstract
Background and Objective: Salmonellosis is a gastroentritidis which caused by the different serovars of Salmonella genus, and responsible for morbidity and mortality worldwide. Food born disease is one of the growing problems of human societies especially in developing countries. The aim of this study was to evaluate and serogroup determination of Salmonella isolates from food along with antibiotic resistance pattern.
Methods: This descriptive study was performed on total of 400 in equal of 200 packed and 200 unpacked samples of (red meat, chicken meat, egg, vegetable) collected in random from distributed in Tehran ,Iran during nine months in 2018. Microbial, biochemical and serological test was performed according to protocol number of 1800 of national standard. Antimicrobial susceptibility test was done by disk diffusion (MAST, Co, UK) method.
Results: Out of 400 samples 8 (2%) was identified as Salmonella. The unpacked foods were more contaminated (75%) compared to packed foods (25%). The most isolated serogrouping were belonging to especially D. Salmonella. The chicken samples were more contaminated (37.5%) than other samples. The isolated Salmonella were mostly resistance to nalidixic acid (75%).
Conclusion: The Salmonella isolated particularly from group 1 showed higher antimicrobial resistance, additional care should be taken in preparation, packaging and supplying the food samples.
