STOCKHOLM (AP) — Furniture retailer Ikea says it has halted all sales of meat balls in Sweden after Czech authorities detected horse meat in frozen meatballs that were labeled as beef and pork.

Ikea’s Swedish branch said on its Facebook page Monday that it won’t sell or serve any meatballs at its stores in Sweden out of concern for “potential worries among our customers.”

It said its own controls had not shown any traces of horse meat.

It wasn’t immediately clear whether Ikea would also stop selling meatballs in other countries.
