Algae, blue-green

Severity scale:

Have you ever wondered what that blue-green stuff is growing in a pond? Well that would be a nasty bacteria known as blue-green algae. Blue-green algae can be found in both a mixture of fresh and salt water, and fresh water, and often are noted in places such as streams, lakes, and backyard ponds. This algae is more commonly seen in the warmer months when the water temperature is higher. There are many species of this bacteria and each one should be considered toxic. The most common systems damaged by algae are the brain and liver, with common signs including diarrhea, tense and tremoring muscles, paralysis, blue skin and gums or yellow eyes, skin, and gums (depending on the toxin), drooling, weakness, difficulty breathing, and coma. Depending on the species of algae, signs can begin within minutes of ingestion, so immediate veterinary contact is recommended.
