Investigation of Beta-lactam Group Antibiotics Residue in Raw Cow Milk in Sivas Province

Abstract

In this study, beta-lactam group antibiotic residues were investigated in raw cow's milk. For this purpose, a total of 86 raw milk samples were used as material. Samples were collected periodically from farms in various outlets and surrounding villages in the province of Sivas. Beta-lactam group antibiotic levels in raw cow's milk were determined by ELISA method with commercial test kit. According to the analysis results, beta-lactam levels were between 0.35-0.70 ng/mL in 64 (74.4%) and between 0.71-3.7 ng/mL in 22 samples (25.6%) determined of 86 raw cow milk samples. The residue levels detected in the samples are in accordance with the legal limits declared by the European Union (EU) commission and Turkish Food Codex Communique.
