Health officials are trying to determine why there's been a dramatic increase in the number of people in Texas each year who contract a food-borne illness that's often linked to produce imported from Mexico and other warmer climes.
Although there have been outbreaks in several states in recent years, cyclosporiasis infection rates returned to normal levels after the sources were contained.

Cyclosporiais is an intestinal illness caused by a parasite that infects people who consume contaminated food or water.
