Is it safe to swim or fish in Jacksonville? See latest health advisories, test results

Whether it's a holiday weekend, a vacation or just a desire to spend a little quiet time in sand and surf, Florida is known for its beaches.

And swimming with enteric bacteria — think fecal pollution — is just plain gross.

We've gathered the latest test results and health advisories from the Florida Department of Health and Florida Fish and Wildlife Conservation Commission to help you stay safe before you head out.

What is enteric bacteria and what are the symptoms?

Enterococci are enteric bacteria which normally inhabit the intestinal tract of people and animals. It's an indication of fecal pollution. It may come from stormwater runoff, pets, wildlife or human sewage.

They can be ingested while swimming or enter the skin through a cut or sore.

Symptoms include upset stomach, diarrhea, eye irritation and skin rashes.

Blue-green algae are types of bacteria called cyanobacteria. They can be blue, bright green, brown or red, and can have a strong odor similar to rotting plants, according to the Florida Department of Health.

If people or animals splash in the water or if boats create wakes, the algae cells can be broken apart, and the cyanotoxins can be released into the air. The toxins mix with water droplets and spray, causing people and animals to potentially inhale the toxin.

Water from areas with blue-green algae can make animals and people sick. These toxins can't pass through your skin easily so swallowing large amounts of contaminated water is what causes illness.

For some people, exposure to blue-green algae can cause rashes, stomach cramps, nausea, diarrhea and vomiting. People who are very sensitive to smells can have respiratory irritation. Sometimes, high exposures of toxin can affect the liver and nervous system.

Karenia brevis is a naturally occurring, single-celled organism belonging to a group of algae called dinoflagellates.

Red tide can cause coughing and sneezing and can irritate your eyes, nose and throat. Reactions to red tide can be worse for people with asthma, emphysema, bronchitis or any chronic lung disease, according to the Florida Department of Health.

Swimming in or around red tide can cause skin irritation, rashes and burning and sore eyes. If you come into contact with red tide, wash off with soap and water, especially if your skin is easily irritated.

Red tide toxins also can accumulate in filter-feeders such as oysters and clams, which can lead to neurotoxic shellfish poisoning in people who consume contaminated shellfish.
