Visitors to the beaches and their pets should be aware of the risk of contact with water where a HAB was found. Boaters and jet skiers are cautioned also that water spray contact on skin or breathing/inhaling water droplets may cause health problems. Toxins may cause a skin rash, blisters, or hives. Vomiting, diarrhea, dizziness, tingling, numbness, sore throat or headaches are some symptoms of illness. In severe cases, liver or kidney damage may occur.
