Food Poisoning (Foodborne Illness), First Aid 

For cases of severe foodborne illness, such as with botulism, the physician may clear out the digestive system by removing undigested food from the stomach and giving medications to induce bowel movements.

Maintaining adequate fluid and electrolyte balance and controlling blood pressure are important. Oral rehydration therapy may be administered, and dialysis may be needed until the kidneys can function normally.
