Blue-Green Algae: What is it?
Blue-green algae is not actually algae, but a type of bacteria called cyanobacteria. It is harmful to livestock and humans when it produces toxins, which happens as the cyanobacteria dies off. These toxins can attack the liver and nervous system and cause sickness or even death. Some common signs that an animal has ingested these toxins include staggering, gastroenteritis, convulsions and difficulty breathing.
