Veterinary Drugs Screening

The Veterinary Drugs Project is a complete research and development method designed to quantify a suite of veterinary drugs added to seafood feed which can be harmful to humans. Examples of these drugs are chloramphenicol, enrofloxicin, ciprofloxacin and sulfa antibiotics.

The method consists of a straightforward extraction followed by instrument analysis on a liquid chromatograph time-of-flight mass spectrometer (LC/TOF MS). The instrument can measure very low levels (ppb) due to its sensitivity. Chloramphenicol is presently analyzed in parts per billion (ppb) on the LC/TOF MS as a confirmatory method to NSIL’s ELISA protocol using an immunoassay (ELISA) kit measured in parts per trillion (ppt). Data gathering and comparative analysis is in process using the two methods.
