Globalization and the rise of fish importation has led to an increase in mislabeling. To combat this problem, analytical and molecular methods have been employed. First, nitrofuran metabolites were extracted, hydrolyzed, and derivatized in channel catfish, swai, and tilapia. Utilizing high performance liquid chromatography coupled with triple quadrupole mass spectrometry, derivatized metabolites were detected at levels of 1 ng/mL with coefficients of determination greater than 0.998. Recoveries greater than 90% and relative standard deviation less than 17% indicate that the method is successful. Secondly, chip based electrophoresis coupled with restriction fragment length polymorphism was used for the species differentiation. By analyzing restriction digestion products, fragmentation patterns from fin-clip and muscle could consistently differentiate different species requiring two or fewer endonucleases for positive identification. This method of screening reduces the expertise, time, and expense required to reduce fish mislabeling. In tandem, these methodologies could significantly reduce the dangers of fish mislabeling.
