Dogs, children can be affected by cyanobacterial toxins in contaminated lake, pond water, Bucks County warns

Harmful Algal Blooms affecting Lake Galena at Peace Valley park in Bucks County contain toxic cyanobacteria that is harmful to pets, children and humans alike.

According to the Bucks County Parks & Recreation Department, cyanobacteria is already present in lakes, ponds and the like, but a bloom – a rapid population growth – of the algae can release cyanotoxins.

The department said HABs rise in levels as water temperatures increase in the summer.

HABs can resemble foam, spilled paint, bubbling scum, green streaks or dots, and even clumps of silky strands, per the department. Colors can range from blue-green to orange to red. The unpleasant rotting odor found near lakes is likely the bloom dying off and decomposing.

People and pets can come into contact with the harmful, contaminated water through recreational water sports, inhaling droplets, drinking the water, or eating contaminated seafood. Symptoms of cyanotoxins include skin, eye and nose irritations, diarrhea, vomiting and abdominal pain.

Dogs are especially prone to cyanobacterial poisoning, said the department, and can get it from drinking water, eating washed up mats or scum of toxins, or even coming into contact with the water. Particularly, dogs are drawn to the HAB odor and can even ingest the toxin while grooming themselves.

Should a pet or person come into contact with contaminated water, immediately rinse off with clean, fresh water and soap.  

“Get medical attention immediately if anyone shows signs of illness, and contact a veterinarian if a pet appears unwell,” they said. “Avoid further contact with the water and report the incident to local health authorities.”
