On the heels of a national recall of several discount brands of toothpaste that were laced with a Chinese toxic chemical
, now it seems some tubes labeled as Colgate were also tainted. Colgate says it didn't make the toothpaste, and that the tubes sold in New York, New Jersey, Pennsylvania and Maryland discount stores were counterfeit. The tubes were labeled as if they were made in South Africa, but investigators said they couldn't be sure about the origins, and the counterfeiter hasn't been identified. Diethylene glycol, a cheap but toxic substitute for glycerine, is found in antifreeze and other chemical products that none would use to brush his or her teeth, according to a story in the June 15 Los Angeles Times.
