Fever and time: In the disease it is more likely to have fever and last longer (days vs hours).

Similar: Food poisoning is due to infection found in the food eaten. It is usually bacteria and the response is fairly soon after ingesting the food. Contagious gastrointestinal disorders are usually viral and usually occur 1-2 days after the exposure. Food poisoning is more commonly nausea and vomitting, viral infections are more diarrhea. But you can experience both with either.
