A pill found in a carton of milk purchased from a convenience store here last week was non-toxic, a dairy producer official says.

The FBI has taken the product-tampering case, said Leland Anderson, chief executive officer for Western Dairymen Cooperative Inc. of Salt Lake City.The incident was reported by Kathy Walters of Porterville, who said she found the pill when she bought milk Friday at a Texaco convenience store and poured it into her baby's bottle.

She said the capsule was white with a red tape around the center, and that the bottle was sealed and the milk smelled fresh.

"All I can say is it's a non-toxic item," Anderson said Monday, adding that the pill had been placed back in the milk after its discovery and had dissolved by Monday.

He said he couldn't say why the capsule was put back into the 12-ounce bottle.

About 3,000 of the containers were distributed under the Cream O' Weber label in the same-day lot, number 49-08, Anderson said. The lot was recalled, but he said it was too early to tell how many bottles had been bought and how many had been returned.

No other capsules had been found, he said Monday.

FBI Special Agent Tim Screen said the matter was being investigated, but he said policy prevented him from answering specific questions about ongoing cases.
