Step 1
Keep your distance (as much as possible) from people who have gastroenteritis. You have no way of knowing if their stomach ailment is a viral or bacterial illness. Thus, you do not know the amount of contagion that surrounds the ill person.
-
Step 2
Wash your hands often with anti-bacterial soap. This is particularly important after using the restroom, changing diapers or when you have come in contact with a sick person or animal.
-
Step 3
Note the sanitation and hygiene practices around food handling anywhere you eat. Poor habits in these areas may cause a nasty bout of gastroenteritis due to food poisoning.
-
Step 4
Clean all surfaces on cabinets and counter tops with hot water and bleach in order to kill germs. This action goes a long way toward preventing an upset stomach of any kind.
-
Step 5
Refrigerate all leftovers as soon as possible after a meal is over. Keep foods warm prior to the meal.
-
Step 6
Educate yourself on how quickly certain foods spoil. Eggs are particularly quick to spoil. Any food that is spoiled causes food poisoning.
-
Step 7
Travel all you want—even to another country—but use bottled water. The water in another country may be unclean and should not be trusted until you are sure about it.
