 Some beaches across the country have been shut down due to high levels of bacteria. Officials in at least 10 states have either closed beaches or are warning people not to swim in the water. Some of the closures are due to fecal waste, while some are due to high levels of blue-green algae. Florida, Illinois, Michigan, New Jersey and New York have all reported unsafe levels of waste at certain beaches. High bacteria levels have also been reported at beaches in California, Iowa, Massachusetts, Vermont and Virginia.
