Veterinary Drug Residue Analysis

Food Environment Safety Analytical Testing Lab

80% of the US consumption of seafood is imported and 50% of it is sourced from aquaculture operations. As the seafood aquaculture industry expands, concerns for the use of unapproved veterinary drugs have increased. The FDA has issued an import alert on seafood due to the alarming increase in unsafe levels of antibiotics and antimicrobials such as chloramphenicol, nitrofurans, dyes, sulfonamides, and quinolones.

Multi-Class Veterinary Drug Residue Test

Sulfonamides, trimethoprim, fluoroquinolones, quinolones, triphenylmethane dyes, and methyltestostereone is tested by LC-MS/MS. A quantitative matrix matched calibrated analysis.

Sample type: Salmon, Shrimp, Crab, Lobster, Trout, Tilapia, Eel, Pangasius, Sablefish, Swai

Method Origin: FDA LIB 4562
