Nestlé, the world's biggest food company, has removed beef pasta meals from shelves in Italy and Spain after tests revealed traces of horse DNA.
Deliveries from a German supplier have been frozen.
Nestlé, the latest in a string of major food producers to find traces of horsemeat in beef meals, said last week that its products did not contain horsemeat.
Levels of horse DNA have been quoted as very low but above 1% by a Nestlé spokesman
The company is said to have withdrawn two chilled pasta products, Buitoni Beef Ravioli and Beef Tortellini, in Italy and Spain.
Lasagnes a la Bolognaise Gourmandes, a frozen product for catering businesses produced in France, will also be withdrawn.
All products will be replaced with meals that are made from 100% beef, which will be proven with DNA testing.
