The Wyoming Department of Environmental Quality, the Wyoming Department of Health and the Wyoming Livestock Board are currently experiencing an increased number of inquiries regarding harmful cyanobacterial blooms (or HCBs) in Wyoming waters. HCBs typically occur in still or slow-moving water as temperatures increase during the summer. They are episodic and can last for a few hours or a number of months.
The occurrences are most common, but not exclusive to eastern Wyoming waters. Cyanobacteria, also known as blue-green algae, can form blooms that produce toxins and other irritants that pose a risk to humans, pets and livestock; including possible fatality.
Jackson Hole Radio Veterinary Correspondent Dr. Stephanie Ninnemann explains catastrophic reaction to the toxins can be very rapid.
Dr. Ninnemann says If an animal becomes infected, its best chances are if it is taken to a veterinarian as quickly as possible. She says there is no antidote, and treatment is only symptomatic until the episode is over.
The Wyoming DEQ points out that in humans, young children, pregnant women, people with weak immune systems and animals are especially at risk. Cyanobacteria is a naturally-occurring biotoxin.
