Blue-Green Algae Blooms Expected This Summer
Written by Comms Team, July 15, 2024
Public Beaches Will Be Monitored
Peterborough Public Health (PPH) is advising residents to protect themselves and their pets from blue-green algae (BGA), which may bloom in local lakes.
Blue-green algae are a type of bacteria, known to create “blooms” of algae. These blooms are not only unsightly and smelly but can be toxic to humans and animals when touched or consumed. Possible effects for humans and animals include skin rash and eye irritation. If consumed in large quantities, the toxin associated with BGA can lead to illness and death.
BGA occur in waterways naturally, particularly where water is shallow, slow-moving and warm. In the context of rising temperatures and extreme weather with climate change, BGA blooms are increasing. BGA presents in various forms as it is blooming and then dying off. As it is difficult to identify a toxic bloom, residents are advised to avoid all algae blooms. Residents relying on private water supplies, especially surface water supplies, should not use the water if a blue-green algae bloom is suspected.
Peterborough Public Health continues to inspect public beach water regularly and will close local beaches if BGA is identified. Check beach water testing results before heading to the beach https://www.peterboroughpublichealth.ca/your-health/beaches-and-pools/beach-testing-results/.
For private water ways, BGA can be reported to the Spills Action Centre at 1-800-268-6060 or online at https://report-pollution.ene.gov.on.ca/
