Monitoring work undertaken on behalf of the Food Standards Agency has identified raised levels of shellfish toxins in West Loch Roag - Miavaig and Eilean Tenish in Lewis.
Eating shellfish such as cockles, mussels or razor fish from these areas may pose a risk to human health and notices to warn the public and casual gatherers have been posted at various locations on the shore. Commercial shellfish harvesters in these areas have been contacted by the Comhairle and steps taken to postpone harvesting until algae levels subside.
It is a sensible precaution to avoid eating shellfish from these areas until further notice.
The council is monitoring the situation and will remove warning notices when it improves.
The high levels of shellfish toxins identified in Loch Leurbost in Lewis on 07 July 2012 have returned to safe levels.
The warning against eating shellfish from this area has now been lifted.
