Discard the top shell & run knife under the clam to release from bottom shell. Put a leaf of lettuce on the bottom of the dish & fill with ice. Place half a dozen clams on top of the ice. Serve with a wedge of lemon, tobasco sauce & cocktail sauce.
Where Is it Found?
Vibrio vulnificus is found naturally in coastal waters. Vibrio vulnificus is NOT a result of pollution, and can be found in waters approved for oyster and clam harvesting. Vibrio vulnificus does NOT change the appearance, taste, or odor of oysters or clams.
Research shows that Vibrio vulnificus is found in oysters and clams from warm waters, such as the Gulf of Mexico. During the warm weather months of April though October, amounts of bacteria found in shellfish are higher.
