New harvesting ban off Dorset after toxic oysters found

The naturally-occurring toxins, found in a sample from The Fleet, can cause Diarrheic Shellfish Poisoning (DSP), BBC News reported.

Anyone experiencing DSP symptoms, which include diarrhoea and vomiting, were told to consult their GP by the Weymouth Port Health Authority.

Last year, a month-long ban was put in place after poisonous oysters were pulled from the lagoon.The restrictions were lifted after two consecutive samples of oysters tested negative for the toxins.

The current temporary harvesting ban does not apply to crustaceans like crabs and lobsters, or gastropods like whelks. The situation will be monitored and the ban lifted as soon as possible, the port authority said .
