A boatload of potatoes shipped from P.E.I. to Algeria is being unloaded, at least partially, following reports of ring rot-infected potatoes on board.

The issue first came to public attention in the P.E.I. legislature Thursday. Agriculture critic Jim Bagnall pressured the government for information on the shipment. Few details were forthcoming at that time.

The Canadian Food Inspection Agency has confirmed to CBC News that there are ring rot-infected potatoes on the ship, but the potatoes in question are from Quebec. Algeria requires that imported potatoes be free of ring rot.

Produce from P.E.I. was also on board, but standard testing found it to be free of ring rot, and since it was stored separately on the ship, it is being unloaded.

The fate of the Quebec potatoes is not yet known. CFIA said the potatoes were shipped before lab results were returned, and so went out at the exporter's risk.
