Raised levels of algal toxins in Argyll lochs Published:  12 October, 2010

Monitoring work undertaken by Argyll and Bute Counci’ls environmental health service has identified raised levels of naturally occurring algal toxins currently in some lochs in Argyll and Bute.

The following lochs have been closed West Loch Tarbert – closed 6 October; Loch Na Keal and Ulva – closed 7 October; Loch a Chumhainn, Isle of Mull – closed 7 October and these lochs re-opened: Loch Fyne, Stonefield – re-opened 8 October; Colonsay, The Strand and Islay, Gruinart – re-opened 4 October.

Loch Striven was closed on July 15 and remains closed. 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 Council 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. Monitoring work is currently being undertaken by the council to evaluate this situation and when the situation subsides, the warning notices etc will be removed.
