STOCKHOLM (AP) — Swedish furniture giant Ikea became entangled in Europe's widening meat scandal Monday, forced to withdraw meatballs from stores across Europe amid suspicions that they contained horse meat.

Stores in the U.S. and Canada were not affected, Ikea said.

The company reacted after authorities in the Czech Republic said they had detected horse DNA in tests of 1-kilogram (2.2-pound) packs of frozen meatballs that were labeled as beef and pork. The Czech State Veterinary Administration said it tested two batches of Ikea meatballs and only one of them contained horse meat. It did not say how much.
