Hunters urged to use caution near water with blue-green algae

BISMARCK, N.D. – The North Dakota Department of Environmental Quality cautions hunters to watch for potentially toxic blue-green algae in wetlands and lakes. Blue-green algae can produce cyanotoxins, which, if ingested, can cause severe health effects in dogs and humans.

Common side effects for humans exposed to water containing cyanotoxins include diarrhea, vomiting, numb lips, tingling fingers and toes, dizziness, rashes, hives, and skin blisters.

Canine deaths, seizures, vomiting, and skin irritation have all been linked to these blooms. There are no known antidotes for cyanotoxins.

Officials say to beware of algae that looks like grass clippings floating in the water, clumps/puffballs, or green cottage cheese. Affected water may also appear like of spilled green paint or green pea soup and is commonly bright green or turquoise in color.

If you or your hunting dog accidentally swims in water that might have an algal bloom, rinse off with fresh water as soon as possible.
