The United States Food and Drug Administration (FDA) refused 19 shipments of Canadian canola meal from Cargill after finding they contained the harmful bacteria salmonella, according to Reuters. Reports posted on the FDA''s Web site say the shipments all come from Cargill''s Clavet, Saskatchewan canola-crushing plant. It was already under shipping restrictions from the FDA for earlier canola meal shipments with salmonella, along with two plants owned by Bunge and one by Viterra. Canola meal is used as livestock feed for cattle and as such, the Canadian canola industry has suggested it should not be treated as strictly as food products. The restrictions against Canadian canola plants have resulted in a sharp drop in overall canola crushing volumes in Canada, which is the world''s largest exporter of canola seed.
