Queensland Fisheries Minister Craig Wallace closed 500 square kilometres to fishing in and around Gladstone Harbour in response to fish disease and illness in commercial fishermen on September 16.

The day after the harbour was closed the acting chief health officer Dr Michael Cleary was quoted as saying "... seafood that showed signs of damage, deterioration or disease should not be handled or eaten. Anyone who has concerns about their health, which might be attributed to the handling or consumption of seafood from the local area should seek medical advice."
