Gastroenteritis is a swelling of the lining of the stomach and intestines, frequently accompanied with acute diarrhea and vomiting, mild fever and stomach cramps. Gastroenteritis attacks can take from anywhere between six hours to 3 days to pass. Symptoms ordinarily are caused by toxins produced by bacteria in the food or by a swelling of the intestine through having a virus or bacteria being present. Ordinarily, food poisoning results in a much quicker onset of symptoms, which can strike the sufferer within the hour of eating infected foods.
Gastroenteritis is frequently connected with diarrhea given it occurs most often in the home ordinarily resulting from poor hygiene. Pre-cooked meats particularly chicken, raw egg dishes and shellfish are the most frequent causes of bacterial and viral gastroenteritis. Further culprits include foods which are past their sell by dates. Seafood's and to some extent dairy products, often smell bad when they have gone off, but this does not always the case with other foods. It is therefore extremely important to store food correctly and always consume before its use by date.
