Examine the contamination of Epinephelus coioides with Listeria and Salmonella bacteria in Khuzestan coastal zone
Environment conservation journal
Listeria and Salmonella species are high risk for human through contaminated foods; these bacteria are psychrophilic and could grow at low temperature even at refrigerator. Fish and shrimp and other aquatic organisms are very good resources for these kinds of bacteria. These bacteria are known as food-borne bacteria because infected of human by foods. These bacteria have been isolated from fresh and processing aquatic foods in the most countries. In this research, two different organs including
... intestines and gills from each fish were prepared at sterile condition for isolation of salmonella and Listeria. Listeria was indentified according to FDA and also salmonella was characterized according to impedance method. From total examined 60 fish, 18 fish was contaminated to salmonella and 3 fish was contaminated to Listeria respectively. The frequency of Salmonella and Listeria in Mahshahr fish was 0.30 and 0.05 and in Hendijan fish contamination with salmonella was 0.05 and contamination with Listeria was not reported. S. paratyphi, S. typhimurium B and S. cholera-suis C were identified in Mahshahr fish, but in Hendijan, fish was characterized S. paratyphi and S. typhimurium B. L. murrayi was only isolated specie from Mahshahr fish. These two pathogenic bacteria have contaminated Khuzestan coastal zone through human resources, animal waste, waste water and chemical industries. Therefore people receive these kind bacteria through consumption of aquatic contaminated marine foods.
