Officials in multiple states, including Florida, Illinois, Michigan, New Jersey, New York, Vermont, Iowa, Massachusetts, and California, have closed beaches or issued warnings due to high levels of bacteria in the water, including fecal waste and cyanobacteria (blue-green algae). These closures and advisories are meant to protect people from potential health risks, as swimming in waters with high bacteria levels can lead to gastrointestinal illness and skin infections, particularly for children, older individuals, and those with weakened immune systems.
Research suggests that cyanobacterial algal blooms, which produce toxins that can harm the kidneys, liver, and reproductive system, may be increasing due to climate change. In addition, heavy rainfall can increase bacteria levels in the water by picking up fecal waste from the environment and carrying it into bodies of water.
Officials recommend checking local health department websites for updates on water quality and safety warnings at beaches. Additionally, individuals can help minimize bacteria in the environment by cleaning up after pets and properly disposing of trash to prevent animal feces from entering the water.
Despite the closures and advisories, only a small percentage of beaches in each state are affected, with Massachusetts estimating that around 5% of beaches are closed throughout the season. By staying informed and taking preventative measures, beachgoers can help protect themselves and the environment from harmful bacteria levels.
