Officials mentioned “health and safety concerns” as the main reason for taking their decision.

The Florida red tide organism, known as K. brevis, produces brevetoxins that can affect the central nervous system of fish and other vertebrates, causing these animals to die.

Wave action can break open K. brevis cells and release these toxins into the air, leading to respiratory irritation in humans.

For people with severe or chronic respiratory conditions, such as emphysema or asthma, red tide can cause serious illness.
