Abstract :

Background: Many occupational zoonotic diseases of multiple etiologies are encountered among abattoir workers. Hand washing is one the preventive measures through which dissemination of bacteria can be prevented. Objective: This study aims at assessment of exposure of abattoir to Escherichia coli and determined the possible source of the bacteria. Results: A total of one hundred and sixty five (156) hand swab samples from workers; one hundred and thirty (130) cattle carcass and fecal samples were collected. The results have shown that no Escherichia coli O157:H7 was isolated on the hands of abattoir workers before and after work. However, a total prevalence a prevalence of 9.7% was recorded for all the samples during work. Oily two abattoirs were found to have E.coli O157:H7 on the hands of abattoir workers while working. For non-O157:H7, total prevalence of 33.3% during work and 13% after work were obtained. Total prevalence of E.coli O157:H7 and non-O157:H7 were 11% and 49% respectively in the carcass samples. The occurrence rate for E.coli O157:H7 and non-O157:H7 were 10% and 81% respectively in the fecal samples. Findings: High risk of exposure to pathogens may occur during animal processing. The effectiveness of hand washing in reducing the exposure after work is low. Conclusion: Exposure to E.coli occurred most frequently during cattle processing and the possible source of contamination according to our findings may be the fecal matter of the slaughtered animal.
