Officials in at least 10 states have closed beaches or issued warnings due to high bacteria levels, including fecal waste and cyanobacteria. States such as Florida, Illinois, Michigan, New Jersey, and New York have reported unsafe levels of fecal waste, while Vermont has warned people against swimming in waters with excess cyanobacteria. Excessive bacteria levels in water can cause gastrointestinal illness, skin infections, and long-term health problems, especially for vulnerable populations.
Environmental research has found that more than half of U.S. beaches have experienced at least one day with unsafe levels of fecal contamination in 2022. Research suggests that climate change is contributing to an increase in cyanobacterial algal blooms, which can produce toxins that may harm vital organs. High bacteria levels have led to beach closures in states like Iowa, Massachusetts, and Florida.
Officials advise people to stay informed about water quality levels at beaches, as they can change frequently. Beachgoers are encouraged to clean up after their pets and properly dispose of trash to prevent animal feces from contaminating the water. Despite the closures and warnings, these instances represent only a small fraction of the thousands of public and semi-public beaches in the U.S.
It is important for individuals to take precautions when swimming in natural bodies of water and to follow safety guidelines to minimize the risk of exposure to harmful bacteria. By being proactive and practicing responsible beach behavior, people can help maintain the health and safety of their local waterways.
