BISMARCK, N.D. (AP) — North Dakota’s Health Department is warning residents to avoid blue-green algae that can develop in bodies of water.Hot summer weather contributes to the production of the algae that’s also known as cyanobacteria. People and animals who ingest affected water can get sick and even die. There’s no known antidote for toxins blue-green algae can produce.

People are urged to avoid water that looks discolored or scummy or has a foul odor. Mike Ell of the department’s Division of Water Quality says algae blooms are most common in the late summer in North Dakota.gae
