Commercial shellfish safe: industry

Seafood lovers shouldn't be turned off by news of poisonous toxins in wild shellfish which have led to the hospitalisation of people in Tasmania, industry groups say.

Three people required treatment for potentially fatal paralytic shellfish poisoning after last weekend eating wild mussels harvested from the state's east coast, where waters are infested by a naturally occurring algae.

The trio has now recovered, the state health department says.

Consumers of commercially available mussels and shellfish should have confidence the products are safe, industry groups insist.

"Commercial Australian mussel and shellfish production is routinely monitored to maintain safe supply of product on the market," national SafeFish spokeswoman Alison Turnbull said on Thursday.

Only wild variants of the shellfish, harvested from Tasmania's east coast, pose a threat.

Commercial shellfish harvesting sites in the region have been closed because of the algal blooms.

While the blooms continue, people are warned not to harvest or eat wild oysters, mussels, clams, pipis, scallops, abalone, rock lobster or crab from the east coast.
