Detection of antibiotic residues by a novel rapid test in cow’s milk from north Algeria

Detection of antibiotic residues by a novel rapid test in cow’s milk from north Algeria Veterinary treatments, particularly antibiotics used for therapeutic or prophylactic purposes in dairy cattle, can be the cause of antibiotic residues in raw milk. The aim of this study is to investigate the use of antibiotics in the dairy cattle industry and to detect the presence of antibiotic residues in raw milk at collection centers using the SNAPduo ST Plus Test in the Bouira and Bordj Bou Arreridj (BBA) regions of Algeria. The results of the survey of 114 breeders showed that the Montbeliarde and Holstein breeds are the most dominant in the farms studied, the frequency of veterinary interventions in cattle farming is always, the curative veterinary intervention represents the highest rate and the beta-lactam is the most family used with 46.25% in Bouira and 85% in BBA, then the oxytetracycline was 22.5% and 15% respectively. Regarding the use of antibiotics by breeders, the majority of them use antibiotics for their animals, with 76.25% in the region of Bouira and 91% in the province of BBA. The antibiotic test of 122 samples of raw milk showed that 19.67% (24/122) of the samples were positive for antibiotic residues with the beta-lactam showing the highest value (79.16%) followed by tetracycline residues with 20.83%. This study showed the presence of antibiotic residues in raw milk in the study area, which may affect the health of dairy consumers.
