Determination of Antibiotic Residues in Bovine Milk in Tabriz, Iran

Antibiotics have been isolated and purified for use to control disease-producing bacteria. Drug residues in milk have a potential hazard for the consumer. One hundred cow raw milk samples were collected from Tabriz suburb and Sarab milk collection centers from March 2010 to November 2010 by systematic random sampling methods. All samples were examined by Copan milk test (CHR. Hansen, Denmark). Of all samples 5(5%) were positive for antibiotic residues in cow raw milk in the northwest region of Iran. This study showed that the effective monitoring program must be run in the northwest region of Iran for control of antibiotic residues prescence in milk.
