2018

The study was designed to assess the hygienic condition of local and imported tableegg-shell at Mosul markets. Two hundred local and imported eggs were randomlycollected from the markets and transferred immediately to the scientific research unitin the college of Veterinary medicine / University of Mosul for bacteriologicalexamination. Total counts using four types of medias were used: Standard Plate Countager (SPC), Mac Conkey ager, Violet Red Bile Glucose ager (VRBG) and TryptoneBile X-glucoronide (TBX) for Escherichia coli and fecal coliform bacteria. Resultsshowed that the means of total viable coliform and E. coli bacterial count in the localegg-shell at different markets ranged from 0.3 to 3 x107 on SPC agar, 0.08-10x107 onMac Conkey ager, 0.014-3x105 on (VRBG) and 0.3-7x104 on (TBX) compared with0.032-5x107 on SPC agar, 0.03-3.3x105 on Mac Conkey ager, 0.014-5.9x104 on(VRBG) with no growth on (TBX) for coliform and E. coli in the imported table-eggshell at different markets. Biochemical tests for local and imported table egg-shellwere performed. It was concluded that the rate of contamination in the local tableeggs was more than the imported one and the isolates of E. coli bacteria were obtainedonly from local eggs on the TBX medium.
