NEW BRIGHTON, Pa. -- As local students head to class Wednesday morning, some fourth-graders in one district are staying home.

That's after 20 students in the New Brighton School District became sick from food served in the cafeteria.

The children were sent home Tuesday after complaining of stomach aches.

Along with them came a letter from the school district saying the students could have salmonella.

That came after 30 servings of undercooked chicken was served at lunch.

Student Stephanie Rambo said, "I just noticed it on the last piece. That it was like pink and stuff."

"You have enough to worry about with your child's life now you have to worry if you should pack a lunch or not," parent Heather Rambo said.

The New Brighton school superintendent said a health expert will review proper cooking procedures with cafeteria workers Wednesday.
