Food Poisoning and Safe Food Handling - Symptoms

The symptoms of food poisoning usually affect your stomach and intestines (gastrointestinal tract).

  • The first symptom is usually diarrhea.
  • Other symptoms include feeling sick to your stomach (nausea), vomiting, and abdominal (belly) cramps.

The time it takes for symptoms to appear, how severe the symptoms are, and how long the symptoms last depend on the infecting organism, your age, and your overall health.

Understanding Food Poisoning -- the Basics

You can get food poisoning after eating food contaminated by viral, bacterial, or chemical agents. Food poisoning causes mild to severe, acute discomfort and may leave you temporarily dehydrated. Mild cases last only a few hours and at worst a day or two, but some types, such as botulism or certain forms of chemical poisoning, are severe and possibly life-threatening unless you get medical treatment.

The very young and the very old may be most affected by food poisoning. Their symptoms may last longer, and even the types of food poisoning that are typically mild can be life-threatening. This may also be true for pregnant women and people with impaired immune systems, such as those who have long-lasting (chronic) illnesses.

Not all food poisoning results in diarrhea, nausea, vomiting, and abdominal cramps. Some types of food poisoning have different or more severe symptoms. These can include weakness, numbness, confusion, or tingling of the face, hands, and feet.

Gastrointestinal symptoms, such as diarrhea and vomiting, can also be caused by organisms that are not necessarily spread through food. These organisms are mainly spread through water or personal contact. Conditions caused by these organisms include infection with the parasite Giardia lamblia.
