Cyanobacteria are bacteria that grow in water and are photosynthetic (use sunlight to create food and support life). They are one of the largest groups of bacteria and have been found among the oldest fossils on earth. They have also been linked to human and animal illnesses around the world.

This bacteria creates blooms when algae that are normally present in the surface waters grows exuberantly. These algae are present in Freeborn County’s area lakes, marshes, ponds and ditches. A blue-green algae bloom will gloat to the surface, may be inches thick, and especially near the shoreline. Often that scum layer will result in an unpleasant ‘pea soup” water condition. Mid-June to late September is generally prime time for an algae bloom; but they have been observed even under the ice.

Waterfowl hunting season is fast approaching so please keep this advice in mind: “When in doubt — best keep out.” DNR wildlife veterinarians suggest hunters can protect their dog’s health by:

1. Provide clean fresh water for the animal to drink

2. Wash the dog thoroughly after being exposed to unclean water. Toxins can be absorbed through the skin as well as ingested.

3. Do not enter or allow your dog to enter bodies of water where a visible bloom is occurring.
