Tasmanian shellfish growers will have to wait until Wednesday to hear if a harmful paralytic toxin, carried by algae, has spread.
Two East coast oyster growers have stopped harvesting after elevated… levels of the toxin were found at Great Oyster Bay and Norfolk Bay.
People have been warned not to eat shellfish from these areas. Neil Stump from the Tasmanian Seafood Industry Council said the impact was localised and was not affecting markets.
He said growing areas always ramp up testing once the toxin is found.
“There’ll be at least weekly testing, mandatory weekly testing for the presence of the algae,” he said.
“The samples are normally taken Sunday afternoon or Monday and the results of that are normally available by Wednesday.”
In 2013 the Tasmanian oyster industry was hit by a number of contamination scares including an outbreak of norovirus.
Dozens of people became sick after eating shellfish.
In 2012 an algal bloom had a devastating impact on oyster growers in the Great Oyster Bay region.
