As the summer heat intensifies, New Brunswick is seeing more blue-green algae blooms that may carry hidden health risks.
Health officials warn that although most cyanobacteria, also known as blue-green algae, are not dangerous, some strains release toxins.
These toxins can irritate the skin, eyes, and throat, and may cause stomach discomfort if they are swallowed.
Dr. Yves Léger, New Brunswick’s chief medical officer of health, emphasized the need for caution.
He noted that residents should learn to recognize the appearance of cyanobacteria blooms to protect themselves, their loved ones, and their pets.
Surface blooms typically appear blue-green but can also be green, red, or brown, according to a government release.
Benthic mats form along the bottom of lakes and rivers and often wash ashore in dark hues, posing a particular threat to pets.
Officials recommend that New Brunswickers follow these precautionary measures:
- Inspect recreational waters for unusual algae or floating mats before entering.
- Supervise children and pets near water.
- Avoid swallowing lake or river water.
- Bathe or shower after water activities.
- Refrain from swimming with open cuts or sores.
Environment and Climate Change Minister Gilles LePage added that the province is funding research through the Environmental Trust Fund to improve understanding of these toxins and their distribution.
This study aims to shape future efforts to protect public health and the environment across New Brunswick.
