Natural product can not be excluded certain risks even when green-lipped mussel. Green lipped mussels feed on plankton. This includes algae and bacteria and other micro-organisms (particularly the highly toxic dinoflagellates), which in turn produce neurotoxins against their predators. Those must not be automatically toxic to green-lipped mussels, but can carry out enrichment of toxins in the food chain problems. MacKenzie et al. (2002) studied green-lipped mussels from the northern West Coast of New Zealand's South Island land harvested during an algal bloom period in which the green-lipped mussels grew well. Depending on the seasonal growth of algae plankton strength in a whole range of diverse Grünlippmuschelnn algae toxins along a 110km test track along the coast could be detected. Per 100 g live weight could, among other things 94-164 micrograms Yessotoxin, 13.5 to 188 micrograms 45OH-Yessotoxin, from 0.8 to 19.3 micrograms Pectenotoxin 2 and 22-1132 micrograms Pectenotoxin 2-SA and some other algal toxins werden.So found described Morohashi et al. (1999), who had green-lipped mussels collected in 1993 to the New Zealand Coromandel Peninsula, North Iceland, a burden with algae poison Brevetoxin. If the contaminated mussels are eaten by fish, it comes in the organism to a conversion to analogues (Brevetoxin B2 to B4), which in turn can lead to fish kills, but also symptoms of poisoning in humans when these fish are consumed in their raw state.
In New Zealand, the problem of algal toxin exposure has been known for years. Since 1992, the seasonal seawater pollution is consistently registered with marine biotoxins, because again and again food poisoning occur among others by shellfish or fish consumption, which could be attributed to algal toxins.
