Heavy metals in the green-lipped mussel Perna viridis: Are they safe as animal feeds?

The objective of this study was to compare the cited data of Cd and Pb levels in the green-lipped mussels (Perna viridis) with established maximum limits of both metals by European Union (EU) legislation for animal feeds. It was found that most mussel populations from Malaysia (90% for Cd; 87.5% for Pb) and Hong Kong (96.2% for Cd; 100% for Pb) were found to have lower levels of Cd and Pb than the maximum limits for animal feeds by EU. Therefore, both toxic metals based on the feeds of mussel meats on the animals should not pose serious toxicological effects. However, the meat of P. viridis are potential animal feeds similarly to the fish meal. Considering the accumulation of metals in the long term, future biomonitoring of Cd and Pb should focus on animal feed materials on mussel-based origins.
