Abstract
A Total of 170 random samples of imported frozen meat, imported frozen chicken and locally frozen chicken was collected from different markets in Cairo and Giza cities. The samples were transported to the laboratory where they were examined bacteriologically for determination of their sanitary status bacteriological examination of the samples revealed that 87, 80 and 72% of imported frozen meat, imported frozen chicken and locally frozen chicken were positive for Coliforms. E. coli O158 was isolated from 8, 6 and 2.86% of locally frozen chicken, imported frozen chicken and imported frozen meat respectively, while E. coli O86 was isolated from 2 and 1.42% of imported frozen chicken and imported frozen meat respectively. Moreover, E. coli O44 was isolated only from one sample 2% of imported frozen chicken. In addition, other E. coli species were isolated from 5.71, 2 and 2% of imported frozen meat, imported frozen chicken and locally frozen chicken respectively.
E. coli O157: H7 and Salmonella species failed to be isolated in all examined samples. Proteus mirabilis, Pseudomonas, Klebsiella, Enterobacter and Providencia stuarti were isolated at different incidences from the examined samples.
Samples subjected to cooking technique either by (broiling or braising) were found to be negative for both Coliforms, and Fecal Coliforms. Meanwhile salmonellae failed to be isolated from all samples examined (Control and Cooked).
The public health hazard of these microorganisms as well as the recommended measures to improve sanitary quality status of imported frozen meat and frozen chicken either imported or locally produced were discussed.
