Cyanobacteria (Blue-Green Algae) in Inland and Inshore Waters: Assessment and Minimisation of Risks to Public Health (Revised Guidance 2012) 12 Apr 2012

This document, prepared by a Working Group established by the Scottish Government Health and Social Care Directorates, provides guidance to Directors of Public Health, to Heads of Environmental Health in Local Authorities (LAs), and to others in Scotland, on possible risks to public health of cyanobacteria (blue-green algae) in inland and inshore waters. It updates previous guidance under the same title that was published by the Scottish Government Health Directorate previously in 2002, and revised in 2007.

The guidance takes account of relevant peer reviewed literature, expert group guidance from international bodies (e.g. WHO) and the expert opinions of the Working Group members. It takes account of current World Health Organisation (WHO) guidance. The guidance given in this report also provides for  Scottish compliance with the requirements of Article 8 of the revised Bathing Water Directive (2006/7/EC).

The guidance covers:

  • Assessing the Nature and Intensity of cyanobacterial blooms;
  • Asessments of the risks to human and animal health;
  • Risk management and risk communication;
  • communications strategy;
  • and incident investigation.
  • Scottish Government
