Why Screen Malachite Green in Seafood?
Malachite Green and related triphenylmethane dye residues are among the most closely monitored prohibited substances in international aquaculture and seafood trade.
Seafood exporters, processors and aquaculture companies face strict buyer and regulatory requirements because residue problems may result in:
• Shipment rejection
• Import detention
• Buyer claims
• Additional laboratory testing costs
• Delayed payment
• Loss of supplier qualification
Front-end Malachite Green screening helps identify higher-risk batches earlier and supports faster quality-control decisions before export shipment or market release.
