‘Toxin-producing’ blue-green algae found in Hamilton Harbour

Hamilton Public Health has confirmed the presence of blue-green algae in the western shoreline of the Hamilton Harbour.

Officials say the toxin-producing bacteria were found at the Bayfront Park boat launch, Pier 4, Harbour West Marina, and throughout the marinas on Macassa Bay.

Blue-green algae are microscopic, plant-like organisms that occur naturally in ponds, rivers, lakes, and streams and can be dangerous to humans and animals.

The city of Hamilton is warning residents to avoid all contact with water along the western shoreline including while launching or moving a watercraft.

If you do come in contact with the water, health officials urge you to wash as soon as possible with clean water. “Facilities for hand washing and rinsing off are available at the Bayfront Park Public Washrooms located at the east side of the Bayfront Park parking lot,” said Public Health Services in a news release.

Residents and their pets should not swim or wade in any areas where blue-green algae are visible.

People who come into contact with it or ingest water containing blue-green algae may experience skin irritation, rash, sore throat, sore red eyes, swollen lips, fever, nausea, diarrhea, and vomiting.

Anyone who has recently been in direct contact with the waters along the western shoreline of Hamilton Harbour and is experiencing headaches, fever, diarrhea, abdominal pain, nausea or vomiting is advised to contact their primary care provider.

The city says blue-green algae are expected to subside as the cooler weather arrives in late November, early December.

They say the safety of Hamilton’s drinking water is not affected by this situation.
