The public are being warned to keep an eye out for blue green algae this summer.
Dr. Cristin Muecke, deputy chief medical officer of health said New Brunswickers should familiarize themselves with the blue-green algae’s appearance to avoid the risks.
“We understand residents want to be active and enjoy the outdoors, but they should consider the potential risks of exposure to blue-green algae,” said Dr. Muecke.
The Government of New Brunswick said some types of blue-green algae produce toxins which can cause skin, eye and throat irritation.
According to the release, blue-green algae or cyanobacteria is a naturally occurring bacteria found in New Brunswick’s aquatic ecosystem but, under certain conditions, can increase in numbers to form surface blooms or benthic mats which tend to occur during the warmer months.
Some types of algae which cause more serious health effects such as gastrointestinal illness if consumed. These toxins can also be harmful to fish, wildlife, livestock and domestic animals.
There is an advisory for the Saint John River between Woodstock and Fredericton due to the harmful toxins of some blue green algae.
This can be lethal if consumed.
The algae is commonly blue-green in colour, but can also look green, red, brown, or yellow. Benthic mats form along the bottom of lakes and rivers and can look like clumps of vegetation that can appear black, brown or dark green in the water, but may appear brown or grey once they have dried on shore. They can also be attached to rocks or aquatic vegetation.
“Algal blooms can be unpredictable, so it is important that people always check the water before entering and avoid swimming in areas where there are visible blooms or mats,” said Dr. Muecke.
Other safety advice includes:
- Always supervise young children and pets near recreational waters.
- Do not swallow lake or river water.
- Bathe or shower immediately after swimming.
- Do not enter the water with open cuts or sores.
- Always wash your hands before eating.
- Do not handle benthic mats when wading, fishing or boating.
