Monitoring work undertaken on behalf of Food Standards Scotland has identified raised levels of shellfish toxins in West Loch Roag - Miavaig and Eilean Tenish in Lewis, say Comhairle nan Eilean Siar. 

Eating shellfish such as mussels, cockles, or razor fish from these areas may pose a risk to human health.

Commercial shellfish harvesters in these areas have been contacted by the Comhairle and steps have been taken to postpone harvesting until algae levels subside.

It is a sensible precaution to avoid eating shellfish from the loch until further notice.
