ABSTRACT

The current study was conducted to isolate Salmonella serovars from swine fecal samples, piglet rectal swabs, pork (meat, knife swabs) and associated environment (water, feed, and floor swabs). A total of 700 samples which included pig feces (300), piglet rectal swabs (100), pork (180), knife swabs (20), water (25), feed (20), and floor swab (55) were collected. From 700 samples processed, 28 (4%) isolates of Salmonella could be recovered. Based on categorizing the samples source-wise the occurrence rate was maximum in cases of pig fecal samples of around 5.5% (22/400) followed by environment samples as 4% (4/100) from and the least by 1% (2/200) from pork samples. Statistical significance was noticed between occurrence of Salmonella with source wise classification as well as with health status of pigs (P < 0.05). But no statistical significance was noticed between occurrence of Salmonella with classification based on age, sex and type of farms (P > 0.05). Even though isolation rate of non-typhoidal Salmonella (NTS) from pork was comparatively less when compared to feces the basic transmission from farm to fork has led to multiple foodborne outbreaks in the past decades which has to be focused. Hence detailed studies targeting NTS in swine environment should be done periodically to avoid unnecessary foodborne transmission to humans which further can elevate the ongoing global issue of multi drug resistance.
