Mulualem Ambaw


Across-sectional study was conducted from October 30/2017-July 30/2019 to determine antibiotic residues in raw bulk milk in Tiyo and Digelu-Tijo milk shades. Qualitative analysis by using Delvotest SP was conducted to screen antibiotic residues. A total of 125 milk samples were collected for antibiotic screening test. From 125 milk samples screened 12% 15/125 were positive for antibiotic residues. The prevalence was associated with presence of mastitis, history of use of antibiotics for the treatment of disease in their farms and herd size. The higher prevalence of residues was found in the dairy farms with higher prevalence of mastitis that uses antibiotics commonly for the treatment of mastitis and other disease. The residue occurrence was also higher in dairy farm owners who use antibiotics by themselves for the treatment and prevention of dairy cattle disease than consulting to veterinary for the treatment of the infected animals. The prevalence were statistically significant at (p<0.05). Attention has to be paid to the presence of drug residues in milk by producers, processors and consumers to be aware about the health impact of consumption of antibiotic residue with milk. Finally the use of effective enforcement of milk quality and safety standards is essential to provide the public with safe and wholesome animal product particularly milk and milk products.
