The Centers for Disease Control and Prevention said it is investigating an E. coli outbreak in seven midwestern states linked to organic baby spinach.

The spinach was sold under the brand Josie's Organic Baby Spinach. It's sold in stores nationwide in plastic clamshell containers. The spinach has a "Best by" date of Oct. 23.

According to the CDC, Minnesota officials found E. coli in a package of Josie’s Organics Baby Spinach collected from the home of a person who got sick. Five people tied to the outbreak reported eating spinach in the week before they got sick, while one person specifically reported Josie's Organics, said the agency.

As of Nov. 15, 10 people infected with the outbreak strain of E. coli have been reported from seven states including: IA, IN, MI, MN, MO, OH, SD. 

Officials are investigating whether additional products might be impacted.

The CDC advises consumers not to eat the contaminated spinach and wash surfaces or items that may have come into contact with the spinach.

Most people infected with E. coli experience severe stomach cramps, diarrhea, and vomiting, says the CDC.

Consumers should contact their health care provider if their symptoms become more severe. Most people recover without treatment after five to seven days, says the agency.
