Screening of antimicrobial drug residues in camel in Tambool slaughterhouse, al Gazira state, central Sudan

Abstract EN

This study was carried out to investigate the veterinary drug residues problem and the potential risk factors associated with it in Tambool area.

Five hundred and seventy-four tissue samples (liver, muscle, lung and kidney) were collected at different seasons from 162 camels from Tambool slaughterhouse.

One_Plate microbiological test for antibacterial drug residues was used for screening these samples.

Forty-two camels (25.9 %) were positive for risk of veterinary drug residues.

For the tissue samples, the results showed that there is no association with potential risk factors except in season (chi-square 80.9, P-value ˂ 0.000) with a highly significant difference in logistic regression of Autumn (Exp (B) 45.9, P-value ˂ 0.000) which also showed the highest percentage of positive camel samples (22.2 %).

Out of 574 tissue samples, 64 showed a zone of inhibition ≥ 2 mm (35 livers, 13 muscles, 13 lungs and 3 kidneys) and 120 samples showed a zone of inhibition ˂ 2 mm.

The liver revealed the highest mean zone of inhibition (2.79 mm) from the edge of the sample in Autumn, and this is an indication of the misuse of veterinary drugs in that season, which will clearly affect the health of consumers so the animal resource ministry should pay attention and put emphasis on the development of a rapid test for antimicrobial residues and national monitoring and controlling programs must take place.
