The Boston Public Health Commission alerted residents to a cyanobacteria algae bloom affecting the Charles River Lower Basin downstream of the Massachusetts Avenue Bridge on Friday.
Residents are urged to avoid contact with the water and any areas of algae concentration, even on shore.
Department of Public Health Staff said an assessment of the pond found cyanobacteria exceeding DPH guidelines for recreational waterbodies in Massachusetts.
According to health officials, the bacteria produces toxins that can make people and pets sick.
What to do if you come into contact with algae
- Pet owners are advised to call their veterinarian immediately if their pet develops symptoms like vomiting, drooling, or convulsions.
- Symptoms present themselves soon after exposure. Dogs have been known to eat algae that washes ashore and touches their fur.
- If you or your pet comes in contact with the water or algae on the shoreline, rinse off immediately.
The Massachusetts Department of Public Health will continue to monitor the cyanobacteria levels in the area.
