High levels of toxins in shellfish have been discovered in Harris.

The Food Standards Agency and Comhairle Nan Eilean Siar (Western Isles Council) have urged people not to eat shellfish such as cockles, mussels, or razor fish from the Seilebost Sands as they could pose a risk to human health.

Notices warning members of the public about the dangers have been posted at various locations in the area.

Commercial shellfish harvesters have been contacted by the council and steps have been taken to postpone harvesting until algae levels subside.

The notice is Seilebost is the fourth currently in place for toxin problems in the Western Isles.

The other three are in the Loch Roag area on the west coast of the Isle of Lewis.

It is not clear what is causing the raised levels of toxins.
