Abstract | Salmonella is most important food-borne pathogen and commonly associated with water and food-borne outbreaks. Approximately 1 .4 million cases of salmonellosis were reported in the USA each year and similarly, outbreaks were reported in the Asian and European countries (D'Aoust, 1989). The incidence of salmonellosis over a period (1988-1992) in USA showed the 7.4% outbreaks were associated with the consumption of fish or shellfish (Bean et al., 1997). Prevalence of Salmonella contamination in seafood in imported and internal market of the United States was reported in a ten year study from 1990 to 1998 by field laboratories of USFDA and demonstrated that 11312 imported (7.1%) and 768 domestic (1.3%) seafood samples were positive for Salmonella (Heinitz et al., 2000). The contaminations in the coastal areas and the post harvest handling in seafood have been found responsible for Salmonella contamination in fish and seafood (Hatha and Lakshmanaperumalsamy, 1997; Kumar et al., 2009). There is a report on influence of environmental factors and human activity on the presence of Salmonella serovars in the marine environments of Galicia region in Spain (Marti nez-Urtaza et al., 2004). In most of the cases, Salmonella load in food and feed samples are reported to be low in numbers (Seo et al., 2006; Boughton et al., 2007). In such cases, sometime culture method may not be able to detect the presence of Salmonella. Thus, it is important to quantify the presence of contaminant in food items so as to establish the quantitative microbial risk assessment measures. |
