Stomach Flu or Food Poisoning (answer 3)

If no one else ate the same questionable food as you and it took more than 8 hours for you to get sick, then it may be too difficult to determine if your sickness was from the food. Perhaps you physician can figure it out. Assume that you have something contagious and seek medical help if you get, too sick. There is a type of food poisoning caused by Clostridium perfringens that produces bad diarrhea the day after you ate the food. So, if your problem is diarrhea instead of vomiting, you could have that.
