The problems with poisonous mussels have increased globally the last
20 years and because of this an extensive control organ has evolved.
The first poisonous mussels in Sweden were observed during the autumn
of 1983. The poisonous mussels were said to suffer from DSP, PSP or
ASP (Diarrhetic, Paralytic or Amnesic Shellfish Poisoning, that is
diarré developing, paralyzing or causing loss of memory). The
most common is DSP and the poison in question is known as DST (Diarrehetic
Shellfish Toxin). The poisons are stored in the mussels hepatopancreas,
which is an organ that functions in the same way as the pancreas and
liver in humans. The toxins have no apparant effect on the mussel,
but consumers of such mussels became sick. If it is shown that the mussels contain any toxins, the area is closed
for harvesting until the tests give a negative result. In the Netherlands,
the mussels are sometimes moved to toxic free Marine areas. Experiments
have been done to try and detoxify mussels, but none as yet, have
had positive results. |
