The U.S. Food and Drug Administration (FDA) along with the Centers for Disease Control and Prevention (CDC) and Texas officials have been investigating an outbreak of Cyclospora infections in the state of Texas.

Four hospitalizations have been reported in Texas. Texas state health officials reported that most cases of the illness occurred in June and July 2014.
