Abstract
Growth of cross contaminant bacterial pathogens such as enteropathogenic Escherichia
coli (EPEC) and Salmonella typhimurium were examined in fish muscle maintained at 50C, 20oC
and 350C to mimic the different conditions prevailing in the retail fish markets. While the
cells hardly grew in fish muscle kept at 50C, there was 5 log and 4 log increase in number
of cells of EPEC and S. typhimurium respectively at 350C. The growth of these cells at 20oC
was more gradual and the increase in the number of cells was around 3 log. The results
indicate potential danger posed by these contaminant bacterial pathogens to the consumers
of temperature abused fish, which is a very common sight in the retail markets of India.
Implementation of minimum standards for the fish markets, regular monitoring and
enforcement are suggested to ensure food safety.
