ORLANDO, Fla. -

The Orange County Parks and Recreation Division shut down the swimming area at Lake Mary Jane in Moss Park in Orlando due to high levels of bacterial contamination in the water, according to a news release sent Friday.

The county closed the swimming area along the lakefront located on Moss Park Road and said it will remain closed indefinitely.

Life guards stayed on duty until dusk, after posting signs and taping off the beach. It's just an early sign of more to come with the long, hot summer ahead.

"I had no clue. We just came and they told us at the front that it was closed due to bacteria. I didn't know they could close because of that," said Kevin Martinez, who came to the area from New York with his family.

But Alicia Gonzalez knew the risk, and when she saw the swimming area was closed, she wasn't taking any chances with her kids.

"I definitely don't want my kids in that water if it has too much bacteria," she said. "It's alright as long as they're safe and no bacteria."

Health experts say bacteria grows in shallow water, and multiply during summer months. The same goes for deadly amoeba that are found in calm, fresh water. To protect yourself from illness from freshwater swimming, wear noseclips when swimming, jumping in water.
