With summer just around the corner, many people are eager to enjoy their favorite swimming spots. However, it's crucial to be aware of potential bacteria alerts in lakes and rivers to ensure a safe swimming experience.

Recently, reports of E. coli infections emerged from Lake Anna, Virginia, primarily affecting children, with some requiring hospitalization. In Massachusetts, 22 beaches were closed due to "bacteria exceedance," accounting for more than half of the closures, while three beaches in Seattle were also shut down due to high bacteria levels.

Cyanobacteria, also known as blue-green algae, pose another significant risk. These bacteria rapidly proliferate and produce toxins harmful to humans and animals. Factors such as excessive nutrients in water bodies, increased sunlight and heat contribute to cyanobacteria blooms. Exposure to cyanobacteria causes a range of symptoms, including skin irritation, stomach cramps, vomiting, diarrhea, fever, sore throat, headache, muscle and joint pain, mouth blisters, seizures and acute liver damage.

Another rare but deadly threat is Naegleria fowleri, a brain-eating amoeba found in warm freshwater sources like lakes and rivers. Infection occurs when water containing the amoeba enters the body through the nose. Although the number of infections is low, they are typically fatal. To reduce the risk, swimmers should shower before and after swimming and avoid allowing water to enter their noses.

To ensure a safe swimming experience, it is recommended to conduct a self-risk assessment before entering the water, check for warning signs, talk to lifeguards, and stay informed. By taking these precautions, you can enjoy a safer and more enjoyable time at your favorite swimming spots this summer.
