Food poisoning, also called foodborne illness, is illness caused by eating contaminated food. Infectious organisms — including bacteria, viruses and parasites — or their toxins are the most common causes of food poisoning. Infectious organisms or their toxins can contaminate food at any point of processing or production. Contamination can also occur at home if food is incorrectly handled or cooked. 

Food poisoning symptoms, which can start within hours of eating contaminated food, often include nausea, vomiting or diarrhea. Most often, food poisoning is mild and resolves without treatment. But some people need to go to the hospital. 

Drug overdoses are now the leading cause of accidental death in the United States. In fact, more Americans die of drug overdoses than in car accidents each year. In light of these staggering statistics, 24/7 Wall St. recently conducted a new study that reviewed and categorized 25 of the most dangerous drugs and drug mixtures. Researchers took into account side effects and death rates tracked by the federal government, as well as potential risk of drug combinations measured by medical information organizations and web sources such as MedScape, WebMD, and the American Medical Association.
