Abstract:
Rectal swab samples of 114 pigs from rural area (Rural-Pigs) and 772 pigs from industrialized farms (Farm-Pigs), including 154 pork samples from supermarkets (Regular-Porks) and 39 pork samples which originated from specific-free pathogens farm and sold in supermarkets (SPF-Porks) were examined for Salmonella. The results Found Salmonella 6.1, 3.1, 77.9, and 82.1%, respectively. The causes of contamination of Salmonella on pork should be from impropered slaughtering process, transportation, cutting and handling. Therefore, it should be improve slaughter-house hygiene, proper transportation as well as cutting and handling processes. Salmonella Anatum, S. Rissen, S. Panama, S. Derby, S. Agona, S. Typhimurium, S. Worthington, S. Schwarzengrund, S. Hadar, S. Stanley, and S. Albany were frequenty found serovars in this study. The antimicrobial resistance of Salmonella isolates were tested with Ampicillin, Chloramphenicol, Kanamycin, Nitrofurantoin, Tetracycline, Nalidixic acid, Cipro-floxacin, Furazolidone, Sulfamethoxazole, and Sulfamethoxazole+Trimethoprim. Salmonella isoltes from Rural-Pigs were found 0, 14.3, 14.3, 0, 28.6, 28.6, 14.3, 28.6, 0, and 0%, respectively. Salmonella isoltes from Farm-Pigs were found higher resistances which were 77, 16.7, 25, 4.2, 95.8, 45.8, 20.8, 4.2, 70.8, and 6.7%, respectively. As well as, Salmonella isoltes from Regular-Porks were found 55.8, 16.7, 3.3, 4.2, 72.5, 33.3, 2.5, 0, 55.8, and 51.7%, respectively; and Salmonella isoltes from SPF-Porks were found 55.8, 16.7, 3.3, 4.2, 72.5, 33.3, 2.5, 0, 55.8, and 51.7%, respectively. Besides, multiple-drug resistance ([is more than or equal to] 4 antimicrobial drugs) of Salmonella isolated from Farm-Pigs, Regular-Porks, and SPF-Porks were found 70.8, 56.3, and 46.7%, respectively. While multiple-drug resistance of Salmonella isolated from Rural-Pig was only 14.3%. The non-prudent use of antimicrobial drugs in pig producers has caused antimicrobial resistance pathogens. Therefore, the judicious use of antimicrobial drugs must be concerned to prevent or delay the problem of emerging antimicrobial resistance pathogens and prolong the use of present antimicrobial drugs
