Trace Detection of Malachite Green in Stream Water – Protecting consumer safety with Misa

Malachite green (MG) is a textile dye with effective fungicidal properties, however it is acutely toxic and its metabolites persist in the flesh of fish and mammals, making it a threat to the human food chain. The EU has concluded that contaminated foods containing levels higher than 2 μg/g MG constitute a credible health risk, and several countries have banned malachite green as an aquaculture additive. Despite tight regulation, seafood products contaminated with MG continue to find their way to consumers.

Using Misa (Metrohm Instant SERS Analyzer) to ensure food safety, the rapid and highly sensitive detection of malachite green is achieved in a facile assay format.
