New technology can detect banned substances in seafood

CALIFORNIA - Thermo Fisher Scientific Inc, the world leader in serving science, has developed three food testing methods in response to recent concerns over contamination of imported seafood.

In June, the US Food and Drug Administration (FDA) banned the import of certain fish species from China because of possible contamination with drugs and unsafe food additives - including nitrofuran, malachite green and chloramphenicol - which are prohibited in food products for human consumption. The ban has stimulated significant interest in the development of analytical methods for detecting any trace of these substances in food.

Thermo Fisher now has a range of testing methods, based on its sensitive and reliable liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) technologies, that can detect these substances at the minutest levels.

The three methods use advanced analytical technology of the Thermo Scientific TSQ Quantum family of triple quadrupole mass spectrometers with Highly Selective Reaction Monitoring (H-SRM). It enables trace-level analysis of complex samples such as animal tissue.

"These food testing methods will help public health laboratories and food manufacturers protect the safety of our nation's food supply," said Greg Herrema, President, Scientific Instruments, Thermo Fisher Scientific.

"The sensitivity and reliability that is achievable with Thermo Scientific instrumentation is important in detecting trace levels of the contaminants of concern to the FDA," he added.
