Poisoned food can be a real threat in restaurants, school cafeterias, picnics, large functions, and even inside your own home. Most food poisoning comes around when no one expects it; there are very few cases of premeditated food poisoning.

You have to be on your toes all the time because bacteria is constantly looking for a way to infest your food and then infect your body, diseases like E. coli (Escherichia) and botulism (clostridium botulinum) are out to get you. There are a few way these diseases can be contracted.

Of course, since you're not an idiot, you know that diseases come from bad bacteria. These bacteria can come in the water you drink or in the food you eat.

If the food you are eating has somehow come in contact with intestinal bacteria from a dead animal you could be at risk of those aforementioned diseases, even if the food was just not prepared properly you could still be at risk. Water is often bad when somehow excrements or waste gets into the mix, this is much less common in the states than in countries where the natives use part of the river to bath and then a different part to drink.

To avoid this food poisoning you have to do a number of things: wash your hands, store foods at correct temperatures, thoroughly cook your food, and when eating anything raw make sure it is sanitized. So if you are trying to make homemade sushi, be sure you figure out how to clean the fish before you start eating it.

It is advisable that you go to a professional and get lessons before you start trying to slice a fish into a spring roll and eat it raw, but you do not have to take anyone's advice if you do not want to. Now take into account that infants and seniors are much more at risk.

Infants just have no immunity built up because they are fresh on the planet earth, and seniors have basically spent all their immunity already. So if you are either an infant or an aged adult you should seriously be careful about what you eat, and if you are feeding either an infant or an aged adult keep in mind they are more prone to disease than you are.

So that candy bar you found half eaten on the drive way may not be safe to share with them, no matter how much they ask for it. Most food poisoning will make itself known by symptoms like, nausea, headaches, vomiting, fever, diarrhea, and weakness.

If you have eaten something questionable and feel one or more of those symptoms, perhaps you should check yourself for food poisoning, or you could just stop eating questionable foods.
