Abstract

An analytical method for the determination of fluopicolide in livestock products and seafood was developed using LC-MS/MS. Sodium chloride was added to livestock products and seafood samples and fluopicolide was extracted twice with acetone after acidification with formic acid. The fat from the crude extract was removed using a macroporous diatomaceous earth column, followed by purification with a combination of mini-columns of GC (graphite carbon) and PSA (ethylenediamine- N-propyl silylation silica gel. The average recovery n=5 of fluopicolide from 10 types of livestock products and seafood (cattle fat, cattle liver, cattle muscle, chicken, eel, egg, freshwater clam, honey, milk and salmon. spiked at the MRLs or at the uniform limit (0.01 ppm) was 96- 100°, with a relative standard deviation of 2.3-6.2°. The limit of quantitation of the developed method was calculated to be 0.01 mg/kg.
