Determination of the Campylobacter Contamination of Cattle Meat in Khartoum State

Abstract

This study was conducted to determine the Campylobacter contamination of cattle meat in Khartoum State, from April 2016 to August 2017. A total of 40 swab samples were collected from Al-Kadaro Slaughterhouse in Khartoum North (Bahry) and Karrari Slaughterhouse in Omdurman for total viable counts (TVCs), and to determine the susceptibility of the campylobacter to different drugs. Those samples categorized as follow: 20 swab samples From 6 cattle carcasses were randomly selected from each slaughterhouse (Swab from the knife and another swab from worker hands), 6 swabs from the carcasses after skinning, 6 after evisceration and other 6 swabs sample from the carcasses after two hours of chilling using sterile swabs. TVCs were 2.48 ± 0.037 log10 cfu/ml after evisceration and 2.32 ± .028 log10 cfu/ml after 2 hours of chilling. While the highest level of TVC occurred after skinning which is 4.44 ± 0.83 log10 cfu/ml, both hands workers and knives were Campylobacter free. The percentage of Campylobacter contamination was 55% of total samples. Sensitivity test against certain antibiotics ranged from 4.6 to 59.1% for the total samples, the highest percentage of sensitivity occurred in clostin 10 μg, while the percentage of resistance ranged from 40.9 to 95.4% in azithromycin and kanamicin 30 μg
