The Texas Department of State Heath Services shut down oyster harvesting along its coastline after detecting a toxic type of algae.

The algae, red tide, have been detected along the Texas coastline from Brownsville to Galveston.

The algae contain a toxin that can accumulate in the tissues of oysters, clams, mussels and whelks and can cause shellfish poisoning. Symptoms can include nausea, dizziness, dilated pupils and tingling sensations in parts of the body.

The red tide toxin can also become airborne and cause coughing and irritation to the throat and eyes.

DSHS is advising people to not eat oysters, clams or mussels from Texas coastal waters. Typically, fishers can harvest oysters from Nov. 1 through April 30 in Texas.

The warning does not apply to other types of seafood, like shrimp, crabs and other types of fish.
