These super colossal wild-caught brown shrimp (Farfantepenaeus aztecus) are sold previously frozen and thawed fresh in Costco's meat and seafood case. The U-12 designation means there are 12 or fewer individual shrimp per pound, making these among the largest shrimp available at retail — ideal for impressive presentations, shrimp cocktail, grilling, and steaming whole.

Wild brown shrimp are one of the three major commercial shrimp species native to the Gulf of Mexico and South Atlantic waters. They are prized for their distinctly sweet, briny flavor and firm texture compared to farm-raised varieties. Unlike white or pink shrimp, brown shrimp have a more robust, earthy taste that holds up well to bold seasonings and high-heat cooking methods such as grilling, broiling, and sautéing.

At 4 pounds per bag, this is a bulk purchase suited for entertaining or stocking up. Because the shrimp have been previously frozen, it is recommended to use them within 1-2 days of purchase and not refreeze. Thaw overnight in the refrigerator or under cold running water before cooking.
