ABSTRACT
This study aimed to determinie the presence of Enterobacteriaceae in beef products as luncheon, pasterma , frankfurter and minced meat as these microbes are considered as major cause of foodborne illness.
This study was carried-out on a total of 100 samples of beef products of retailed meat represented by luncheon, pasterma , frankfurter and minced meat (25 of each) were collected from different retail outlets. Each sample was kept in a separate sterile plastic bag and transferred in an ice box to the laboratory under complete aseptic conditions with a minimum of delay . all collected samples were bacteriologically examined for isolation and identification of Enterobacteriaceae.
Our study concluded that,the most important bacteria that isolated from minced meat includes E. coli (44 %), Enterobacter spp. Especially Enterobacter aerogenes (12 %), Enterobacter intermedium (4) and Enterobacter gergoviae (4 %), Citrobacter spp. that includes Citrobacter amalonaticus (4 %), Citrobacter diversus (4 %) and Citrobacter freundii (4 %), serratia spp especially Serratia marcescens 8 %), Serratia ficaria (8 %), Serratia fonticola (12 %), Serratia liquefaciens (4 %) and Serratia rubidaea (8 %), Edwardsiella spp. especially Edwardsiella ictalori (8 %) and Edwardsiella hoshinae (12 %), Povidencia spp. (8 %) especially Providencia alcalifciens (4 %), Klebsiella pneumoniae especially Subsp. Ozanae (4 %) and Proteus spp. especially Proteus mirabilis (12 and 16 %).

Also,the most important bacteria that isolated from pasterma includes E. coli (40 %), Enterobacter spp. Especially Enterobacter aerogenes (8 %), Enterobacter intermedium (4 %) and Enterobacter gergoviae (12 %), Citrobacter spp. that includes Citrobacter amalonaticus (4 %), Citrobacter diversus (12 %) and Citrobacter freundii (4 %), Serratia spp. especially Srratia marcescens (4 %), Serratia ficaria (8 %), Serratia fonticola (4 %), Serratia liquefaciens (4 %) and Serratia rubidaea (8 %), Edwardsiella spp. especially Edwardsiella ictalori (12 %) and Edwardsiella hoshinae (8 %), providencia spp. especially providencia alcalifciens (8 %), Klebsiella pneumoniae especially subsp.
