Raised levels of shellfish toxins have appeared in Seilebost Sands in Harris.
Eating shellfish such as cockles, mussels or razor fish from these areas may pose a risk to human health.
Warning notices will be posted at various locations on the shore.
Commercial shellfish harvesters in these areas have been contacted by Comhairle nan Eilean Siar.
The council said it is a “sensible precaution” to avoid eating shellfish from these areas until further notice.
Toxin levels continue to be measured.
