The U.S. Food and Drug Administration, while emphasizing there is no evidence of tampering, says it will test samples of a diarrhea medicine blamed for oral burns suffered by an Ogden man.

LeRoy Gomez, the FDA's district director in Denver, said results of the tests would not be available for several days.Kaye Bennett, spokesman for Upjohn Co., which makes Kaopectate, said the particular batch to which the suspected bottle belonged could have been distributed throughout the country.

However, the Kalamazoo, Mich.-based company said it had received no other complaints as of Tuesday and had not recalled the product.

Smith's President Jeff Smith said all Kaopectate bottles of the same lot as the one involved in the incident had been pulled from the chain's shelves. He said there were fewer than 100 in all.
