LARAMIE, Wyo. (AP) — This isn't going to help kids eat their vegetables.

About a dozen preschoolers at Linford Elementary School in Laramie were taken to the hospital Tuesday after eating sample-sized portions of either yucca, the cactus, or yuca, with one c, the root vegetable, as part of a push to get students to eat new types of fruits and vegetable.

Superintendent Brian Recht said the district's food supplier couldn't confirm which of the two were served. Both are potentially harmful if not properly prepared.

The Associated Press reported that one preschooler reported nausea and officials warned other parents to take their children to the hospital for observation. The district hasn't confirmed whether the nausea was related to the food.

Samples were also served at other schools but no one reported getting sick.
