French vegetable group Bonduelle has confirmed the acquisition of Europe's largest mushroom producer France Champignon from private-equity group Butler Capital Partners.

The leading European mushroom firm, with annual turnover of around EUR200m (US$275m), will become a wholly-owned subsidiary of Bonduelle, based in Saumur (Maine et Loire), the firm said today (4 February).

Butler Capital bought France Champignon in 2004 and has overseen a business that has five facilities in France and one in Poland. The mushroom firm's annual sales stood at EUR212m (US$304.1m) in 2008.

Bonduelle owns a range of canned and frozen vegetable businesses in Europe and Canada.

France Champignon employs around 1,500 people and produces 130,000 tonnes of mushrooms in all forms - canned, frozen, fresh, pasteurized and dried.

The acquisition remains subject to the approval of competition authorities in France and Germany, in which cases were filed in early January.
