Richardson is no longer the only Canadian canola producer being shut out of the Chinese market. There are now 18 members of the group that represents the industry in Canada, including Viterra Inc., Louis Dreyfus Company, Cargill Ltd. and Parrish & Heimbecker Ltd. which say that their contracts to sell in China are drying up. Canada's Minister of Agriculture Marie-Claude Bibeau said China only recently agreed to have scientists assess the claim that they have found organisms in Canadian canola, after they claimed that about Richardson's. About 40 per cent of Canada's canola seed exports last year went to China, worth about $2.7 billion. Canada also sent about $1 billion worth of canola oil to China, and about $500 million worth of canola meal. Up until the recent disruption, Chinese demand for Canadian canola has been strong, the group says.
