Think you love Gulf shrimp? It’s possible you’ve never even tasted it. Last Labor Day weekend, sample genetic testing at the Louisiana Shrimp & Petroleum Festival in Morgan City, Louisiana — where you’d naturally think "Gulf” shrimp was being sold and promoted in a town built on shrimping — revealed that only one of five vendors (Woodreaux's Cajun Cuisine) was actually serving the real deal. Unaware festival goers never thought to question the source as they consumed imported, farm-raised shrimp right next to the Gulf of Mexico.
