Maple Leaf spokeswoman Linda Smith told the Canadian Broadcasting Corp. the recall involves 1,100 cases of wieners that were shipped to eastern Canada, mostly to Ontario.
The broadcaster said people who bought 450-gram packs of Shopsy's Deli Fresh All Beef Frankfurters (product code 20730 and UPC 6487520730, best before date of April 22 and 23) and Maple Leaf Hot Dogs (product code 22356 and UPC 6310022356, best before date of April 23) are advised not to consume them.
Smith said the wieners had been quarantined for a second round of testing at a plant in Hamilton, Ontario, but were mistakenly shipped out prematurely. Initial testing had produced a partial positive result for a listeria species, Smith said. Maple Leaf says it tests for all six listeria species.
No illnesses had been reported but it was not known whether the recalled wieners tested positive for Listeria monocytogenes, which was blamed for last year's deadly listeriosis outbreak. The deaths of 17 people were linked to Maple Leaf products in that case.
"Unlike other situations, this event occurred as a direct result of human error and did not uphold our stringent industry leading protocols," said Michael McCain, president and chief executive officer of Maple Leaf Foods.
