Malachite Green


Rapid CDIATM MG kits are intended for qualitative detection of Malachite Green in aquatic products.


Malachite green (MG) is used as a dyestuff and controversially as an antimicrobial in aquaculture and commercial fish hatchery industries and for humans. Malachite green is both carcinogenic and genotoxic. The extensive usage of MG dye has caused several health hazards and hence, MG is unauthorised for use in food-producing animals in the EU. 


MG is metabolically reduced by fish to leucomalachite green (LMG). When fish exposed to MG reach the consumer, the amount of LMG present in the fish is expected to be higher than that of MG. LMG induces hepatocellular adenomas and carcinomas in female mice via a mutagenic mode of action. The World Health Organization Committee did not recommend MRLs for malachite green and leucomalachite green, as it did not support the use of malachite green for food-producing animals.
