Erie, Pennsylvania (WJET/WFXP/ — A total of 19 Erie County water access areas have been deemed hazardous to dogs due to harmful algal blooms.

The Erie County Department of Health website notes that “harmful algal blooms” are a misnomer — it is not algae, but rather a bacteria that acts like algae. It can be seen on the surface of the water in colors like blue, green, white, brown or red. The algal blooms produce toxins.

There are three separate thresholds for HAB toxin levels — a dog safety threshold, a human advisory threshold, and a human restriction advisory.

Dogs have specific warnings because their threshold is lower than people. They ingest water when they swim, and they lick their fur when they get out of the water making them more susceptible to higher doses of the harmful bacteria.

Weekly testing is performed by the Regional Science Consortium and reported to the county health department.
