Salmonella bacteria cause about 1.35 million infections in the United States every year, and outbreaks have been tied to sources such as cucumbers, eggs, unpasteurized milk, fresh basil, geckos and pet bearded dragons.

At least 345 people — the majority in Colorado and Minnesota — have been sickened by a salmonella outbreak, according to the U.S. Centers for Disease Control and Prevention.

A salmonella outbreak has been linked to jalapeño peppers sold at two Mexican fast food restaurants.
