- Abstract
The present study was conducted to determine the bacterial contamination and prevalence of foodborne pathogens in imported frozen fish. A total of 450 imported fish samples [65 catfish (Pangasius pangasius), 45 mirgal (Cirrhinus mrigala), 135 tilapia (Oreochromis niloticus), 50 carfoo (Cyprinus carpio), 75 Rohu (Labeo rohita), 35 milk fish (Chanos chanos) and 45 Mackerel (Rastrelliger brachysoma)] were randomly purchased from different supermarkets. The samples originated from 5 countries, namely, Thailand (n=260), India (n=75), Vietnam (n=35), Myanmar (n=35) and Bahrain (n=45). The isolation and identification were done according to standard bacteriological analytical methods. Out of total samples, 49.1% (95%CI: 44.52 to 53.72) were positive for foodborne pathogens. The highest percentage of positive bacterial contamination were from Vietnam milk fish, 65.7% (95%CI: 49.15 to 79.17), followed by Catfish from Thailand, 58.5% (95%CI: 46.34 to 69.64) and Mirgal from Thailand, 57.8% (95%CI: 4330 to 71.03). The leading bacterial contaminations and foodborne pathogens in these samples were: E. coli (18.6%), Enterococci (14.4%), Pseudomonas (14%) and Salmonella (16.8%), respectively. Correspondingly, the country with the highest odds for pathogens is Thailand, 1.0472 (95% CI: 0.8217 to 1.3347) and the fish with the highest odds for pathogens is Tilapia 0.6667 (95%CI: 0.4000 to 1.1112) followed by catfish, 1.4074 (95% CI: 0.8636 to 2.2938). In Saudi Arabia and to date, comprehensive data regarding the bacterial contamination and prevalence of foodborne pathogens in imported frozen freshwater fish are limited or not available.
