The Fisheries Department has issued a red tide warning confirming that certain shell fish north of Cape Columbine are not safe to consume.

The affected shell fish to be avoided at this stage are mussels, oysters, clams and any other filter-feeding shellfish.
DAFF has confirmed that rock lobster remain safe for consumption.
Red tides are caused by a mass proliferation of phytoplankton and can essentially be various shades of orange, yellow, purple or brown depending on the type of phytoplankton, densities and even the sun.
