Additional Information:

The Texas Parks and Wildlife Department and the Texas Department of State Health Services investigate reports of possible red tide along the coast and in the bays.

Three common signs of a red tide bloom are:

  • discolored water
  • dead fish
  • breathing difficulty.

From the Centers for Disease Control:
The human health effects associated with eating brevetoxin-tainted shellfish are well documented. However, scientists know little about how other types of environmental exposures to brevetoxin—such as breathing the air near red tides or swimming in red tides—may affect humans. Anecdotal evidence suggests that people who swim among brevetoxins or inhale brevetoxins dispersed in the air may experience irritation of the eyes, nose, and throat, as well as coughing, wheezing, and shortness of breath. Additional evidence suggests that people with existing respiratory illness, such as asthma, may experience these symptoms more severely.

To report sightings of red tide during normal business hours, call your local TPWD office or 361-825-3244. Outside of normal business hours you may call TPWD's 24-hour communications centers at 512-389-4848 (Austin) or 281-842-8100 (Houston.)

Although some travelers may be concerned with how the red tide may affect their vacation plans, there are miles of clean beaches to enjoy on the Texas coast. When making travel plans, heed the advice of the Texas Department of State Health Services : get the current facts and draw your own conclusions.
