What is salmonella?

Salmonella is a bacteria that can give you an infection called salmonellosis. Most human infections are caused by the consumption of food that is contaminated with the bacteria, the Centers for Disease Control reports.

The bacteria is named after Dr. Salmon, the American scientist who discovered it in the 19th century, according to the CDC.

What are the symptoms?

Contracting an intestinal infection from salmonella can lead to diarrhea, fever and abdominal cramps. These symptoms usually appear within three days after infection and usually go away in 4-7 days.

How common is salmonellosis and how often do patients die?

There are about 1 million food-related illnesses caused by salmonella contracted in the United States each year. Of these, about 19,000 people are hospitalized and 380 die.
