A member asked:

How long does it take to become sick after being exposed to the stomach flu. it's been almost 4 days and i haven't caught it yet but worried ?

A doctor has provided 1 answer

Faster than that: Food-borne illness hits hard and fast, anywhere from 30 minutes after a contaminated meal with certain bacterial toxins from killed bacteria to a day or two if there are live pathologic bacteria present in the food. longer periods without symptoms would be unusual.
