Consuming raw or undercooked meats, poultry, seafood, shellfish, or eggs may increase your risk of foodborne illness, especially if you have certain medical conditions.
If you have chronic illness of the liver, stomach, or blood – or if you have immune disorders – you are at greater risk of serious illness from raw oysters; and you should eat oysters fully cooked.
IF UNSURE OF YOUR RISK, CONSULT A PHYSICIAN.
