People who are allergic to seafood must avoid eating oysters.

Filter-feeding shellfish can accumulate Vibrio bacteria.  It’s possible that eating them raw will raise your risk of infection. Infections with these bacteria can cause symptoms like diarrhea, fever, vomiting, and more serious illnesses like septicaemia, a life-threatening blood infection.

Oysters can also transmit noroviruses and enteroviruses, both of which can be harmful to your health.
