Nestle, the world's biggest food company, has removed beef pasta meals from shelves in Italy and Spain after tests revealed traces of horse DNA.
The Swiss-based firm has halted deliveries of products containing meat from a German supplier.
Nestle is the latest in a string of major food producers to find traces of horsemeat in beef meals.
A spokesman for the company said levels of horse DNA were very low but above 1%.
Last week the firm said its products did not contain horsemeat.
Nestle withdrew 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Lasagnes a la Bolognaise Gourmandes, a frozen product for catering businesses produced in France, will also be withdrawn.
A spokesman for the company told the BBC that Nestle had identified a problem with a supplier from Germany.
