Ontario's chief medical officer on Friday extended a formal confirmation for a genetic link between listeriosis cases and contaminated deli meat manufactured at a federally regulated meat plant.

It is revealed to be the first match since Canada was rocked in the summer of 2008 with a deadly outbreak.

Arlene King said public health officials in Ontario have linked two cases of listeriosis to a genetic fingerprint from Siena Brand Prosciutto Cotto cooked ham.

In addition, the genetic fingerprint is also reported to be a link to Siena Brand mild cacciatore salami.

The food inspection agency's executive director of food safety and consumer protection, Robert Charlebois, claimed that the CFIA has included the faults in its inspection operations that were identified in a report on the August, 2008, listeriosis crisis in which 22 people died and many more were sickened by contaminated meat.

Both the Canadian Food Inspection Agency and Siena Foods Ltd. had called for the tainted salami in December that is reported to be distributed in Ontario and Quebec and may have been distributed nationally.
