Blue Green Algae Common During Hot Weather
On going hot temperatures set the scene for the possible development of algae blooms. The Water Security Agency and the Saskatchewan Ministry of Health are advising the public to avoid direct contact and any consumption of any surface water where blue-green algae blooms are occurring. Blue-green algae blooms can be harmful for household pets and livestock. Residents and producers are advised to keep their animals away from these areas. Algae blooms are heavy concentrations of blue-green algae, which often give the water a shimmering, foamy and often pea soup appearance. The blooms may be blue-green, bright blue, grey or tan in colour. Algae blooms commonly occur during calm, hot weather in areas of lakes and reservoirs with shallow, slow moving or still water that has sufficient nutrients. The blooms can last up to three weeks and can be pushed around the lake or reservoir by the wind. Direct contact or consumption of algae-contaminated water can cause red skin, sore throat, cramps, nausea, vomiting and diarrhea. In addition, caution should be taken when considering the consumption of fish or shellfish caught in areas of a water body where a bloom exists; the internal organs of the fish should not be eaten.
