Food poisoning is caused by infectious or toxic agents. Infectious agents include bacteria, parasites, and viruses. Toxic agents include pesticides on fruits or vegetables, poisonous mushrooms, or improperly prepared exotic foods (for example, barracuda). Symptoms of food poisoning include vomiting, nausea, diarrhea, and abdominal cramps. Treatment of food poisoning depends upon the cause.
Food poisoning is a common, usually mild, but sometimes deadly illness. Typical symptoms include
vomiting, abdominal cramping, and diarrhea that
occur suddenly (within 48 hours) after consuming a contaminated food or drink. Depending on the contaminant, fever and chills,
bloody stools, dehydration, and nervous system damage may follow. These symptoms may affect one person or a group of people who ate the same thing (called an outbreak).
