If you’ve taken a bite of shrimp lately and thought the flavor was off, you may have been on to something.

Oceana, an international ocean conservancy group, released a study earlier this month that found nearly a third of U.S. shrimp sold is misrepresented.

Essentially, grocery stores and restaurants are selling imported farm-raised shrimp as wild-caught Gulf shrimp, which is considered to have a superior taste and texture , according to NBC News.

“Despite its popularity, U.S. consumers are routinely given little to no information about the shrimp they purchase,” Beth Lowell, senior campaign director at Oceana, said.

Using DNA testing, Oceana confirmed that 30 percent of 143 shrimp products from 111 grocery stores and restaurants were mislabeled.

According to Oceana, New York City led the country for misrepresentation of shrimp at 43 percent followed by Washington, D.C. and the Gulf of Mexico region.

The conservancy group says that shrimp vendors aren't giving consumers information on the food's origins and that the majority of restaurant menus observed lacked information on the type of shrimp served.

The Monterey Bay Aquarium considers the farmed shrimp bait-and-switch a sustainability issue, too; their Seafood Watch program says wild-caught shrimp trumps the farm-raised alternative from an environmental perspective .

National Geographic reports that farmed shrimp lands on the aquarium’s “Avoid” list because of concerns that the product degrades habitats and causes pollution.

NBC News says the study’s findings are unsurprising for those involved in the shrimp industry.

“I’ve been shouting this for ages from the rooftop, “ Kimberly Chauvin, who runs a family shrimp business in Louisiana, told NBC News.
