Abstract:
Raw fish naturally have a number of bacteria, and this can be opportunistic and causing foodborne infections rapidly. Staphylococcus aureus are one of the major bacterial agents causing food borne diseases in humans worldwide. The present study was conducted to determine the prevalence of Staphylococcus aureus in raw fish. A total of 60 raw fish samples were collected from the city areas of Bikaner, Rajasthan. The isolation and identification were done according to standard bacteriological analytical methods. The mean total psychrophilic count for them was 8.38 x 10⁴ cfu/gm. Out of 60 raw fish samples, 20 (33.33%) samples were positive for S. aureus. Coagulase production was recorded in 18 (90.0%) S. aureus isolates whereas, 2 isolates (10.0%) were coagulase negative.
