National Potato Council Presses USDA to Re-Ban Fresh Potato Imports From Prince Edward Island

A fresh detection of Potato Wart disease in a Prince Edward Island field with no link to previous finds has prompted NPC and 13 U.S. state potato organizations to formally ask USDA to reinstate its earlier ban on fresh potato imports from PEI, the National Potato Council disclosed. The request came in a May 18 letter addressed to USDA Undersecretary for Marketing and Regulatory Services Dudley Hoskins. NPC Chief Executive Officer Kam Quarles wrote that the new detection "reinforces our continued concerns over the true scope of the disease in PEI production areas," and said the group "renew[s]" its objection to fresh PEI imports.

The detail that matters here isn't just that the disease was found again — it's where. A detection unconnected to any prior known site suggests, per the industry's own framing, that existing containment zones may not reflect the disease's real footprint.

The stakes are economy-wide: potato wart is classified by USDA's Animal and Plant Health Inspection Service (APHIS) as a select agent, one of only seven high-consequence plant pathogens recognized as severe threats to domestic agriculture, the National Potato Council notes. Citing the Canadian Food Inspection Agency (CFIA), the industry notes the pathogen can persist in soil for more than 40 years with no available chemical treatment.

The U.S. potato industry is described as generating more than $100 billion in annual economic activity and supporting over 714,000 jobs. NPC states that a domestic outbreak would trigger immediate loss of access to international fresh potato markets, costing growers more than $225 million in direct annual export losses, with additional indirect economic damage described as running into the billions.

The timeline laid out by NPC shows this is not a first request. A temporary import halt imposed in fall 2021 was reversed by the Biden Administration in May 2022, reopening the border to PEI fresh potatoes. NPC's Board of Directors responded at the time with a resolution stating that federal officials had treated the situation as a "diplomatic inconvenience" rather than a genuine biological threat.

The industry also points to an October 2022 APHIS pathway analysis that itself concluded the "full extent of the potato wart infestation in PEI is still unknown but is likely to be larger than currently reported" — a finding NPC says was not followed by materially changed mitigation protocols. NPC has separately raised concerns about Canada's 2024 National Potato Wart Survey, which it says sampled only 2,200 fields and did not test fields with prior detections.

For years, the U.S. potato industry has urged APHIS to use its existing authority to impose specific risk-mitigation measures: restricting bulk potato shipments, limiting large retail shipments while mandating traceback labeling on consumer packages, and imposing controls on agricultural waste from processing and bulk handling facilities, the National Potato Council notes. NPC states federal authorities have not acted on any of these recommendations.

The letter's closing argument leans on a comparison rather than new evidence: NPC contends that if the roles were reversed, Canada would not tolerate this level of permissiveness toward a threat of this magnitude from the United States. That framing is presented as rhetorical pressure rather than a documented policy fact.

The letter is signed by NPC and 13 state potato organizations spanning major production states, indicating the request carries broad domestic industry backing rather than a single-state complaint. The letter concludes by urging USDA to suspend PEI's ability to ship fresh potatoes into the United States given what NPC describes as disease progression on PEI paired with a lack of enhanced phytosanitary action to date. Whether USDA acts, and how quickly, will determine whether this becomes another entry in the same multi-year cycle NPC's letter describes.
