ARGYLL and Bute Council's environmental health team has identified raised levels of the naturally occurring bacteria Escherichia coli (E.coli) in a sample of common cockles following routine monitoring work at Kerrera, near Oban.  

Because of this, shellfish from the area may pose a risk to health and should not be harvested or eaten.  

As a precaution, people should avoid eating shellfish from this area until further notice.
