Last week everyone was blaming the Tassimo single cup coffee makers for exploding. Now it has been announced that it is the coffee packets themselves that are a problem.

The U.S. Consumer Product Safety Commission and Health Canada, in cooperation with Kraft Foods Global Inc., of Northfield, Ill., is recalling about 2.1 million packages of Tassimo espresso T Discs sold in the United States and an additional 1.9 million in Canada.

The T Discs can become clogged and spray hot liquid and coffee grounds onto consumers and bystanders during or after brewing, posing a burn hazard. There have been 21 reports of incidents of hot liquid and/or coffee grounds spraying onto consumers and bystanders, including four reports of second-degree burn injuries. One injury involved 2-year-old girl from Canada who received second-degree burns to her face. This recall involves Gevalia, Maxwell House and Nabob brand espresso T Discs. The T Discs are plastic discs filled with coffee that are inserted into Tassimo coffee makers to brew single cups of hot espresso drinks.

They were sold in packages of eight or 16 espresso T Discs. T Discs with codes ending with 11213 through 12020 are included in this defective product recall. The code is printed on the T Disc’s foil lid and on the side of the package.
