OTTAWA -- Federal health officials have expanded a recall of Mexican-grown mangoes due to possible Salmonella contamination.

The Canadian Food Inspection Agency first said the mangoes had been sold in all provinces west of Ontario, but now says the fruit may have been sold nationally.

The CFIA says the Daniella brand mangoes were sold as individual fruit with a sticker bearing PLU. 4959 or PLU. 4051 or as part of a multi-pack.

The mangoes were sold between July 12 and up to and including Aug. 28.

The agency says consumers who can't determine which mangoes are affected by the recall should contact the retailer to find out if they carry the affected fruit.

There have been several confirmed illnesses associated with eating these mangoes.

The importer, Mex Y Can Trading Inc. of Mississauga, Ont., is voluntarily recalling the affected mangoes and the CFIA is monitoring the recall.

Food contaminated with Salmonella may not look or smell spoiled.

But eating food contaminated with the bacteria may cause serious and sometimes deadly infections in children, the elderly or those with weakened immune systems.

In otherwise healthy people, salmonellosis may cause short-term symptoms such as high fever, severe headache, vomiting, nausea, abdominal pain and diarrhea.
