Wild Shellfish - Port Esperance

Danger: Do not eat wild shellfish from Port Esperance

Do not eat wild shellfish - toxic algal bloomThis warning was issued on 10 May 2019 and remains current.

Toxic algal blooms (also known as harmful algal blooms or HABs) are present in Port Esperance (the area around the town of Dover in the South of Tasmania). High levels of algal toxins have been detected in shellfish from this region.

Recreationally harvested shellfish should not be eaten because the algal toxins are harmful to humans.

Seek urgent medical help if you get sick after eating wild shellfish.

Symptoms can occur within minutes to hours after eating shellfish. Cooking or freezing the shellfish does not destroy the toxins that cause shellfish poisoning. Shellfish poisoning symptoms include:

  • tingling or numbness
  • weakness
  • blurred vision
  • difficulty breathing
  • vomiting
  • diarrhoea.

Seafood in shops and restaurants is safe to eat because the Biosecurity Tasmania monitors the safety of commercially grown shellfish.

Wild shellfish include: oysters, mussels, clams, pipis, cockles and wedge shells. Abalone, scallop roes and the intestines and livers (tomalley) of rock lobster can also be affected when toxic algal blooms are present.
