TORONTO — Health Canada and the Canadian Food Inspection Agency have approved a genetically engineered potato for sale, said a U.S.-based company on Monday in announcing that its non-browning spuds could be in Canadian supermarkets by Thanksgiving.

J.R. Simplot Company was notified by both agencies in letters dated March 18 that it could sell its potatoes — which purportedly are less likely to bruise or turn brown when cut — to consumers or for livestock consumption.
