Salmonella is a disease caused by a dangerous bacteria found in contaminated food, water, or contact with infected animals. Most people infected develop diarrhea, fever and abdominal cramps 1-3 days after becoming infection. While most people can recover without treatment, recovery may take several months and may have other adverse effects, including pain in the eyes and joints and painful urination. In some persons, diarrhea may be so sever that the patient may require hospitilization. Also at risk are the elderly, infants, and those with pre-existing conditions.
