The presence of residues of veterinary drugs such as antibiotics used for the treatment of animals can be dangerous for the consumer. Indeed, residues of these drugs can end up in the form of undesirable traces in animal productions, in particular milk when there is an inappropriate use such as failure to comply with the waiting times between the administration of antibiotics to the animal and meat collection. This study is part of a global project carried out with the aim of evaluating the presence of antibiotic residues in the raw milk of cows reared in cattle farms in Blida. This study involved 200 milk samples were collected in the Wilaya of Blida. A screening of the samples was carried out by the acidification test followed by a confirmation agar diffusion test. The results showed residues in 20,51 % of the milk tested. The study revealed the presence of antibiotic residues in raw cow’s milk from farms in varying proportions. Penicillin residues and / or tetracyclines were originally of the contamination of 93,62 % milk samples positive while residues macrolide and / or aminoglycoside were only detected in 6,38 % of samples tested positive. The use of antibiotics should be done by veterinarians or under their responsibility by animal health professionals.
