Salmonella germs have been known to cause illness for more than 100 years. People infected with Salmonella develop diarrhea, fever and abdominal cramps 12 to 72 hours after infection. The illness usually lasts four to seven days and most people recover without treatment, according to the Centers for Disease Control and Prevention.

Salmonella can be deadly for young children, the elderly or those with weakened immune systems, as it can even cause death.
