A simple and sensitive method for the detection of Oxytetracycine levels in ready-to-eat beef by liquid chromatography-mass spectrometry
Antimicrobial drug residues have emerged as one of the public health problems worldwide.
In this study, a modified sensitive liquid chromatography mass spectrometry (LC-MS)
method to detect the “Oxytetracycine”(OTC) levels in ready-to-eat beef meat in Tanzania was
evaluated. Beef samples were extracted in acetonitrile in ethylenediaminetetraacetic acid
(EDTA) buffer (pH 4), followed by cleaning up with Supelclean ENVI-carb active coal and a
stream of nitrogen gas. The wavelength of the diode array detector (DAD) was set at 275 …
