Cyanobacteria (also referred to as blue-green algae) are common photosynthetic bacteria that live in surface waters. Under favorable conditions, such as warm water and high nutrient content, these bacteria can form nuisance “blooms”.

Contact with blooms can cause skin rashes and irritation, itchy eyes, and ear infections. Inhaling water may cause allergic-like reactions, runny noses or sore throats. Ingestion of toxins can cause a range of symptoms (e.g., hepatotoxic or neurotoxic effects, and even death). There has been increased public awareness as a result of research over the past 20 years, recent monitoring efforts, and increased public education on the topic. In 2009, Alberta Health and Alberta Health Services began seasonal monitoring for cyanobacterial blooms at high use recreational beaches. In 2019, beach operators took over...

Description

The Safe Beach Protocol was prepared to provide Albertans with a clear understanding of the management of recreational waters in the province. It provides information on the role of owners and operators in overseeing these sites, monitoring water quality and responding to health risks, with the support and commitment of provincial agencies. The information in this document may be of interest to policy makers, researchers, public health professionals, or members of the public who are interested in recreational water sites (beaches).
