Abstract
Salmonella and pathogenic Escherichia coli are two of the most common causes of bacterial foodborne illness all over the world. This study aims to address the existence and characterization of the two pathogens in frozen meat and organs imported into Egypt and to declare their role in causing food poisoning. A total of 1363 (962 meat, 281 liver, 69 heart and 51 kidney) samples were taken from lots arrived at different ports in Egypt. In addition, 47 human vomitus and 13 stool samples were collected from those showing symptoms of food poisoning with history consuming cooked imported frozen meat and liver. Microbiological isolation, biochemical, serological, and molecular identification of isolates were performed. Results revealed high occurrence of Salmonella in all kinds of examined food samples (meat 1.7%, liver 0.36%, heart 1.5% and kidney 3.9%) and also occurrence of E. coli in all types examined food samples (meat 7.7%, liver 13.9%, heart 14.5%, kidney 13.9%). Human samples showed high prevalence of Salmonella (28.3%); however, proved negative for E. coli. Enterotoxigenic (stn) gene of Salmonella was detected in 86.5% of our isolates. Occurrences of these pathogens in relation to country of origin as well as their public health significance were discussed
