The National Potato Council is expressing concerns about the potential entry of potato wart into the U.S. from Canada, particularly from states in the Midwest where the disease can thrive. Currently, a ban is in place on seed potatoes from Prince Edward Island, Canada due to the fungus detected in the past two years, but table stock potatoes are not included in the ban. Studies by the USDA and the Canadian Food Inspection Agency have shown that the threat may be underestimated, with retail grocery stores and consumers potentially introducing the disease. If the disease were to be detected in the U.S., it could lead to a ban on all international fresh potato markets, resulting in a direct cost of over $225 million in annual exports and billions in indirect impacts.
