Abstract

The study was planned to detect antibiotics residues present in beef Ghanawa
slaughterhouse, Khartoum State. The methodology was based on collection of
information from the owners of the cattle (n=50) , and Veterinary Pharmacies
(n=50) by means of questionnaire as well as the One Plate Test (O. P. T.)
employed for estimation of antibiotics residues in different organs of the
cattle. The main results showed that most of the owners did not consult
veterinarians 88% (n=44). Furthermore, the majority of Veterinarians in
Pharmacies 76% (n=38) left dose estimation and administration to the
owners. Using one Plate Test (O. P.T.) revealed that out of 300 cattle 52
(17.33%) showed positive results in one or more of their organs and there was
no significant correlation level recorded for season and antibiotic residues (χ
2
= 0.720, P = 0.698, P > 0.05). Out of 300 kidneys tested, 30 (10%) showed
positive result, while out of 300 livers tested, 23 (7.66%) were positive, and
out of 300 muscles tested 9 (3%) were positive. The age group of 4-6 years
was scored high positive percentage (19.49%), (n=46 out of 236 of that age
group) (χ
2 = 286.260, P = 0.000, P 0.01). Moreover, the cross-breed
had the higher percentage of positive (20%) (n=2 out of 10 of that breed) (χ
2
= 397.293, P = 0.000, P 0.01). In conclusion, the findings of this work
indicated a problem of misusing of antibiotics in cattle for meat production
and the percentage of positive samples was considered to be high.
