Blue-green algae (Anabaena) can produce toxins harmful to humans and animals. These algae levels are likely to be associated with dangerous toxin concentrations in the water. Swallowing or inhaling water droplets from lakes that are showing high levels of toxin should be avoided, as well as skin contact with water by humans or animals. The toxins cannot be removed by boiling, filtering or treating water.
If people choose to eat fish from lakes with dangerously high toxin concentration, they should remove all fat, skin, and organs before cooking since toxins are more likely to collect in these tissues.
Symptoms of numbness, tingling, dizziness and paralysis can lead to difficulty breathing or heart problems and require immediate medical attention. If symptoms of skin irritation, weakness, diarrhea, nausea, cramps and fainting persist or worsen, people should seek medical attention. Children and pets are particularly susceptible.
