The U.S. Centers for Disease Control and Prevention (CDC) are investigating a sharp increase in reported cases of cyclospora, an intestinal infection caused by water or produce contaminated by a parasite.
Since May, 206 cases have been reported to the CDC, up from 88 cases reported last summer, CBS News reports. Officials have not determined the cause behind the increase of cases this year. Past outbreaks have been linked to imported fresh produce, including basil, cilantro, mesclun lettuce, raspberries, and snow peas. The CDC recommends washing all produce thoroughly.
Cases have been reported from 27 states. Earlier this summer 68 people were sickened in Texas.
