With the recent ban on drinking water from Lake Erie, more and more people are aware that blue-green algae is toxic to humans, but what about livestock? Keenan Bishop, writer with The State Journal in Frankfurt, KY, fields questions about algae every year, and his answer is an education in itself. "There are over 2000 species [of blue-green algae] but less than one hundred are poisonous," writes Bishop.
And when it is toxic cyanobacteria? Bishop writes, "Animals can seem weak, stagger, slobber, have trouble breathing and even die. Some algae produce liver toxins. Animals are most at risk when drinking from a water source during a bloom or cleaning their coat or fur after exiting the body of water." Learn more about algae through the link below.
