When you have consumed food or drink that is contaminated, your body will try to dispel the toxins from your body. This is usually by way of vomiting or diarrhea. However, your symptoms and the severity in which you experience them differs from person to person. Some of the most common symptoms include:
· Vomiting
· Headaches
· Abdominal pain and/or cramps
· Dehydration
· Muscle aches
· Nausea
· High temperature
· Diarrhea

There is no specific time frame in which you may first experience the above symptoms, as it depends on the type of food poisoning, and how well your immune system reacts.
