Officials are confirming red tide at County Beach Accesses four, five and six, just north of South Padre Island's city limits. 

Dead fish and aerosal-related symptoms are present.

Red tide produces a toxin that impairs the central nervous system of fish.

They become paralyzed and cannot breathe.

Red tide can cause coughing, sneezing and tearing to people.

Some even complain of irritated skin. 

Those with respiratory problems are asked to avoid red tide areas.

Pets should also be kept on a leash and away from dead fish.

City and county officials will continue to monitor the situation.
