Analysis of Antibiotic Residues in Ovine Meat from Winter Farming, Marketed in The Markets of the Tissemsilt Region.

Abstract

The study focuses on detecting antibiotic residues in sheep meat sold in Tissemsilt, Algeria, as part of an effort to assess the risks posed by antibiotic misuse in livestock farming. Antibiotics are commonly used to treat infections in animals, promote growth, and enhance feed efficiency. However, the misuse of these drugs, especially failure to adhere to withdrawal periods, has led to concerns about the safety of meat products due to potential antibiotic residues. The Four-Plate Test (FPT), a microbiological screening method, was used to detect antibiotic residues in 20 sheep meat samples from local markets. The results revealed that 25% of the samples contained antibiotic residues, primarily from β-lactams and macrolides. This indicates significant non-compliance with recommended withdrawal periods, potentially due to a lack of awareness among farmers and inadequate veterinary supervision. The study also highlighted the widespread use of antibiotics such as tetracyclines, β-lactams, and sulfonamides in the region, with insufficient adherence to withdrawal periods. The findings underline the need for improved awareness among livestock breeders, stricter enforcement of regulations, and regular residue monitoring to ensure food safety and prevent the development of antibiotic-resistant bacteria. Key recommendations include educating farmers about proper antibiotic use, enforcing veterinary oversight, implementing routine residue testing, and establishing a national surveillance system to track antibiotic usage and residue levels in animal products
