The Colgate-Palmolive announcement comes less than two weeks after the U.S. Food and Drug Administration (FDA) warned consumers to avoid any toothpaste made in China after inspectors found DEG in tubes sold at two stores.

Colgate-Palmolive said the counterfeit toothpaste was found in New York, New Jersey, Pennsylvania and Maryland. It can be recognized because it is labeled as being manufactured in South Africa, and the company does not import toothpaste to the United States from South Africa.

The packaging also contains several misspellings, Colgate said. It said it is working with the FDA to help to identify those responsible for the counterfeit product.

DEG-contaminated toothpaste has also been seized in Costa Rica, the Dominican Republic, Panama and Nicaragua. It was also found in cough syrup in Panama that led to the deaths of at least 100 people last year.

The FDA issued its alert about Chinese toothpaste after seizing a batch of Cooldent found to contain 3% DEG. Inspectors found the toothpaste at a Dollar Plus store in Miami and at a store called Todo a Peso in Puerto Rico.

Brands seized earlier included Cooldent, Clean Rite and Oralmax that are usually found at discount retailers, the agency said.

The FDA identified products by Goldcredit International Enterprises, Goldcredit International Trading Co. and Suzhou City Jinmao Daily Chemicals Co as containing DEG.

Goldcredit International Enterprises is a unit of JiangsuXingda Stationery Group, a manufacturer of glue and office supplies. Suzhou City Jinmao Daily Chemicals also makes soap and pet products.
