Three types of potatoes genetically engineered by an Idaho company to resist the pathogen that caused the Irish potato famine are safe for the environment and safe to eat, Canadian officials said recently.

The approval by Health Canada and the Canadian Food Inspection Agency means the J.R. Simplot Co. potatoes can be imported, planted and sold in Canada.

The company said it received approval letters from Health Canada and the Canadian Food Inspection Agency in the last several days. Health Canada spokeswoman Renelle Briand confirmed the approvals to The Associated Press on Thursday.

“We have no objection to the sale of food derived from J.R. Simplot Company’s” potatoes for human consumption, Karen McIntyre, director general of Health Canada, said in a letter sent on July 28 to the company, according to Associated Press.

The three varieties of potato — the Russet Burbank, Ranger Russet and Atlantic — were approved by U.S. regulatory agencies in February.

J.R. Simplot spokesman Doug Cole said the company has been doing experimental field trials in three Canadian provinces: Manitoba, Ontario and Prince Edward Island.
