The Canadian government has suspended exports of fresh and processed potatoes from Prince Edward Island (PEI) to the United States due to potato wart, a fungus. This decision has left potato growers in the province shocked and has led to concerns about the impact on trade and potential increase in grocery store prices in the U.S. The suspension does not apply to frozen potato products. However, the PEI Potato Board disagrees with the suspension, stating that the current testing and control plan is effective in managing the fungus. The two cases of high potato wart detection occurred in fields already under a management plan and were not eligible for export.
