Health officials say two Kansas cases are tied to the cyclospora outbreak that has sickened 372 people in 15 states.

A spokeswoman for the Kansas Department of Health and Environment said Tuesday one patient is from Phillips County. The other patient lives in Johnson County, in the Kansas City metro area.

The spokeswoman, Miranda Steele, says officials believe both illnesses were caused by food eaten in Nebraska.

Iowa and Nebraska health officials say that a prepackaged salad mix is the source of an outbreak of the stomach bug in those two states. Steele says there is no indication the salad mix was distributed in Kansas.

Cyclospora is a rare parasite that causes a lengthy gastrointestinal illness with diarrhea and other flu-like symptoms.
