When in Doubt, Stay Out!
Harmful Algal Blooms Can Occur in All Bodies of Water
Harmful algal blooms (HABs) are a natural occurrence, but they can pose serious health risks to humans and animals. These blooms are often caused by certain types of Cyanobacteria that can produce harmful toxins and are most prevalent in warmer months. The Lake Erie Interagency HAB Task Force is urging visitors to stay vigilant and safe when recreating in and around the water during the summer months.
When harmful algal blooms occur, the water may appear discolored, often resembling thick green or blue-green mats. Toxins that are harmful if ingested, inhaled, or come into contact with the skin can be produced by the algae, and may be present even when visible scums and mats have dissipated.
Safety First
Exposure to HABs can cause skin rashes, respiratory issues, gastrointestinal distress, and more severe symptoms if ingested or inhaled, so be cautious near still waters, such as ponds or slow-moving streams, where these blooms are most likely to occur.
What You Can Do
- Be safe in or near the water
- Avoid swimming, wading, or fishing in areas with visible algae blooms
- Keep pets and children away from areas with visible algae
- Rinse off with fresh water immediately after swimming in areas not affected by blooms.Follow all posted warnings, including signs indicating unsafe water conditions.
Protect Yourself and Others
By staying informed, avoiding areas with visible algae, and practicing common-sense safety measures, you can avoid the risks associated with harmful algal blooms. When in doubt, stay out!
