The Canadian Food Inspection Agency is alerting the public to a recall of fresh apples from the U.S. It says this recall is linked to last month's recall of caramel-covered apples, which has led to several illnesses.

The CFIA says that "Granny’s Best" and "Big B" Granny Smith and Gala apples exported by Bidart Bros. in the U.S. could be contaminated with Listeria monocytogenes.

The latest notice is related, according to the CFIA, to a Dec. 24 recall of caramel apples from the U.S. that has led to at least two illnesses in Canada, as well as three listeriosis deaths in the U.S.

The recalled apples may have been sold in Canada under other brand names besides "Granny’s Best" and "Big B," the CFIA says. They may also have been sold in bulk or without a brand name at all.

Canadian importers of the recalled products include Beauvais Ltee. and Courchesne Larose. The products were also imported by and sold at Coosemans Montreal Inc.

Consumers should not eat the recalled apples and should throw them out. Retailers, restaurants and institutions are also being advised not to sell or use the recalled products.

Consumers who are unsure if apples they bought are included in this recall are advised to contact the location where they were purchased.

Listeria can cause a serious, life-threatening illness, with symptoms that can include headache, nausea, seizures and neck stiffness. In pregnant women, listeriosis can lead to premature delivery or even stillbirth.

Food contaminated with listeria may not look or smell spoiled.

In the U.S., the Centers for Disease Control and Prevention announced last month three recalls of prepackaged caramel apples. All the candy companies received their apples from Bidart Bros.

At least 32 people from 11 states have been infected with the strains of Listeria involved in the caramel apple outbreak. Listeriosis has contributed to three deaths and may have contributed to two more deaths.

The CDC is advising U.S. consumers not to eat any commercially produced, prepackaged caramel apples until more specific guidance can be provided. But the agency says no listeria illnesses have been linked to fresh apples not coated in caramel.

Both the CFIA and the CDC say their investigations are continuing and new information and new recalls could still be announced.
