WASHINGTON (AP) — The Centers for Disease Control and Prevention says some Texas cases in a severe stomach bug outbreak last summer have been linked to Mexican cilantro. The CDC said Wednesday that the cilantro came from Puebla, Mexico, and was served at “Mexican-style” restaurants and sold in a single grocery store. The CDC did not identify the Mexican producer, the restaurants or grocery store.

All told, 278 people in Texas were sickened by cyclospora. Not all those illnesses were traced back to the cilantro. There were two separate cyclospora outbreaks last summer, sickening 643 people in 25 states. The other outbreak was linked to salad mix served at Olive Garden and Red Lobster restaurants in Iowa and Nebraska.

The CDC said the outbreaks are finished and the products are out of stores.
