Iowa City Schools Served Recalled Lettuce

IOWA CITY, Iowa (AP) — Lettuce that had been recalled over fears of Listeria contamination was served at Iowa City Community School District schools.

The district says in a news release that officials were notified about the recall on Monday, after much of the lettuce had already been served. The rest won't be used.

Federal authorities say there have been no reported illnesses associated with the voluntary recall by River Ranch Fresh Foods, of Salinas, Calif.

Symptoms of listeria infection include high fever, headache and neck stiffness.
