WINNIPEG, Manitoba, June 12 (Reuters) - Two rail car shipments of canola meal from Bunge's Canadian crushing plants tested positive for salmonella after inspection by the U.S. Food and Drug Administration at the border in May, Bunge Ltd (BG.N: Quote, Profile, Research) said on Friday.

One shipment that tested positive in early May traces back to the Bunge plant in Hamilton, Ontario, said Bunge spokeswoman Deb Seidel. The second shipment tested positive in late May and came from Bunge's plant in Nipawin in the western province of Saskatchewan.

Both plants are undergoing cleaning, although the Hamilton plant's soy line continues to operate, Seidel said. The company hopes to resume shipping to the United States once it meets all FDA protocols for salmonella, she said.

"We're in the process of cleaning those facilities, making sure everything is OK and working in co-ordination with the FDA and the CFIA (Canadian Food Inspection Agency)," Seidel said.

People who eat food contaminated with salmonella can become ill with salmonellosis, a foodborne illness with flu-like symptoms, according to the Canadian Food Inspection Agency.
