As millions of Americans head to beaches, lakes and other bodies of water this summer, officials are warning about harmful algal blooms that can pose serious health risks to people and pets.

Harmful algal blooms are the rapid growth of algae or cyanobacteria in water that can produce toxins that harm people, animals and the environment.
According to the Centers for Disease Control and Prevention (CDC), these blooms can develop in freshwater, saltwater, brackish water and even drinking water systems.
Some blooms can look like foam, scum, mats or paint on the surface of the water. They can also grow underneath the water, making some harmful algae blooms hard to see.
They occur around the world and have been reported in all 50 states, as well as Puerto Rico and the U.S. Virgin Islands.

While harmful algal blooms can occur anywhere, some states experience them more frequently or on a larger scale, particularly during the summer.
States with recurring blooms include Florida, Ohio, Michigan, Minnesota, Wisconsin, New York, Pennsylvania, New Jersey, California, Oregon, Texas and Washington.
The U.S. Environmental Protection Agency (EPA) said it works with states and tribes to support harmful algal bloom monitoring programs and maintain resources to help the public track advisories and water conditions.

According to the CDC, many different types of algae cause harmful algal blooms, but cyanobacteria, dinoflagellates and diatoms are the most common causes that make people and animals sick.
Other environmental factors, including warm water temperatures, abundant sunlight and excess nutrients such as nitrogen and phosphorus from fertilizer runoff, wastewater, stormwater and agricultural sources can fuel explosive growth.
Climate change is also contributing to more frequent and longer-lasting blooms by warming waterways and increasing the likelihood of heavy rainfall that can wash nutrients into lakes, rivers and coastal waters.
HEALTH ADVISORIES ISSUED FOR POPULAR FLORIDA GULF COAST BEACHES DUE TO FECAL BACTERIA IN WATER
Exposure to harmful algal blooms can cause a range of illnesses depending on the type of algae and how a person comes into contact with it.
People can become sick after swimming or wading in contaminated water, inhaling airborne droplets or eating contaminated fish or shellfish.
Symptoms may include skin rashes and irritation, eye, nose and throat irritation, stomach pain, nausea, vomiting and diarrhea, coughing or difficulty breathing, headaches and dizziness.
Some toxins can also affect the liver or nervous system.

Pets, especially dogs, are vulnerable since they are more likely to drink contaminated water or lick algae from their fur after swimming. Exposure can be life-threatening.
Health officials recommend taking the following precautions:
If exposed, immediately rinse yourself and pets off with clean water. Then contact the healthcare provider of the Poison Control hotline.

Since harmful algal blooms can develop quickly and change with weather conditions, officials encourage checking local advisories before heading to the water, especially during the warmest months of the year.
A few minutes spent checking water conditions could help keep your summer plans on track.
