Current Public Health Advisories and Alerts

 

The Office of the Chief Medical Officer of Health encourages the public to be active and enjoy the outdoors but be aware that cyanobacteria blooms can be unpredictable. The Departments of Health and Environment and Local Government work together to ensure that any reported or suspected bloom is evaluated and that an advisory is posted when necessary. When a cyanobacteria bloom is confirmed, the advisory is posted below.  

Once issued, the advisory will remain in place indefinitely.

Although the body of water indicated may not have an active cyanobacteria bloom, advisories remain on the list for the public to be aware that cyanobacteria blooms have been reported in the past. A recently confirmed bloom does not necessarily indicate that there is a current risk, however waterbodies with a history of cyanobacteria blooms are at a greater risk of future blooms. Additionally, toxins may remain in body of water for several weeks after the blooms are no longer visible.

Future sampling of the area to remove any advisories will not be done due to the unpredictability of cyanobacteria blooms.

The public is encouraged to always check the water before entering or engaging in water activities.

**Dates listed indicate information for blooms that have been reported to the Department of Environment and Local Government. Confirmation is completed by taxonomy for new waterbodies and by photo submission for waterbodies where an advisory was already in place. The absence of a recently confirmed bloom for a waterbody could mean the absence of a cyanobacteria bloom, however a bloom may be present and has not yet been reported.
