SALT LAKE CITY -- A home day-care provider said she found a pill mixed in with candy, and one of the children she was caring for tested positive for opiates, the Salt Lake County sheriff's office said.

Sheriff's Sgt. Mike Morgan said the candy, Nestle Nerds, was purchased at the Smith's Food and Drug store in Herriman. The candy was placed in a bowl and given to the children Thursday.

The day-care provider said she then found a pill in the candy and took it to the Smith's pharmacy, which said it was an extended-release pain medication, Morgan said.

He said the four children, ages 6, 4, 4 and 2 1/2, were taken to Jordan Valley Hospital and examined. The youngest tested positive for opiates and was treated and released. All of the children were released to their parents.

Morgan said Nestle, Poison Control and the FBI were advised of the incident. He said the Smith's store removed its remaining Nestles Nerds from its shelves. He did not know if the store had found anything in the other packages.

Lynn Marmer, a spokeswoman for Cincinnati-based Kroger Co., which owns Smith's, said the company was aware of the tampering allegation and was cooperating with the FBI.

Morgan suggested that anyone who bought the candy recently should inspect the contents.
