Antibiotics residues of some famous antibiotics in raw milk of different species sold at local markets

Abstract EN

Antibiotic residues in milk are of great public health concern since milk is being widely consumed by infants, youngster and adults throughout the globe.

Therefore, eighty samples of different species including (cow, buffalo, camel and sheep) 20 of each type were collected from different markets and dairy shops located in Alexandria governorate, Egypt for detection antibiotic residues using HPLC.

The obtained results revealed oxytetracycline, penicillin G and cloxacillin residues were detected at incidence rate (30, 30, 15, & 30%), (25, 20, 10, & 25%), and (10, 10, 0, &15%) with a mean values of (97.9±28.1, 85.5± 25.9, 48.4±28.0 & 122.9±29.2 ppb); (8.86 ± 3.60, 7.583± 4.73, 1.95± 0.95 &10.2 ± 3.40 ppb), and (39.3 ± 7.40, 21.5 ± 9.05, 0 & 37.6 ± 9.91 ppb) in examined cow, buffalo , camel and sheep’s milk samples, respectively.

Positive samples for antibiotic residues compared with maximum residual limits established by international standards.

In addition, calculated daily intake for each antibiotic residues were compared with acceptable daily intake.

One milk samples may contain one or more antibiotic residues and these may cause public health hazards for consumers.

Therefore, Legislations for monitoring and control antibiotics treatment of food producing animals should be adopted.
