Detection Limits of β-Lactam Antibiotics in Ewe Milk by Penzym Enzymatic Test

摘要

The Penzym is an enzymatic test widely used for the detection β-lactam antibiotic residuals in milk. It is a specific method with good sensitivity to this group of antibiotics and enables results to be obtained within a short time. In the present work, the detection limits of 10β-lactam antibiotics were determined in ewe milk, given the lack of previous studies of the Penzym test in ovine milk. For each antibiotic, eight concentrations were tested on 20 ewe milk samples proceeding from Individual ewes(160 analyses per drug).
