Theres all kinds of bacteria or toxins that make up "food poisoning" and all have different general times for the symptoms to start.....some withn 30 minutes. Just look it up.
I ate clam chowder in Boston last year and didn't feel good leaving the place......went across the street to the Celtics game and within 45 minutes was barfing. Spent most the game barfing then got fever and chills for 24 hours.....had to fly home nearly dying.
That's what bad clams will do.
