Prevalence of foodborne pathogens in meat samples in Palestine
Publication Type
Conference Paper

Foodborne diseases occur worldwide, including those acquired through the consumption
of contaminated meat. This study aimed to investigate the prevalence of enterotoxigenic
Staphylococcus aureus, Salmonella and Escherichia coli pathotypes in different meat types.
Forty meat samples fresh (n=35) and frozen (n=5) were purchased from local markets in Jenin
district, Palestine. Multiplex PCR was used to detect enterotoxigenic S. aureus, Salmonella
and E. coli pathotypes. Total mesophilic aerobic bacterial count ranged between 4.3 log10 to
5.7 log10 cfu/g for frozen meat and 6.95 log10 to 7.78 log10 cfu/g for fresh meat. The prevalence
of S. aureus, Salmonella and E. coli was 30%, 25% and 95%, respectively. Among tested
S. aureus strains 75% were enterotoxigenic. Two other samples of non S. aureus (FemA-)
were enterotoxigenic; one was sec+ and the other was see+. The results also showed that
89.5% of meat samples contaminated with E. coli that belonge to enterohemorrhagic E. coli
(EHEC), enteropathogenic E. coli (EPEC), enteroaggregative E. coli (EAEC), enterotoxigenic
E. coli (ETEC), diffuse adherent E. coli (DAEC) pathotypes. According to these results, it is
recommended to establish a suitable surveillance program for microbial contamination with all
foodborne pathogens.
