The head of a secretive investigation into the deadly outbreak of bacteria linked to ready-to-eat meats will reveal her recommendations today after keeping her findings secret for one extra day.

Independent investigator Sheila Weatherill submitted the final report of her six-month probe — which involved millions of pages of documentation and at least a hundred interviews — to Agriculture Minister Gerry Ritz yesterday and is expected to release it publicly at a morning news conference.

Prime Minister Stephen Harper tasked Weatherill in January with examining the factors that contributed to the listeriosis crisis that killed at least 22 Canadians and sickened hundreds more last summer after they consumed deli meats from a Maple Leaf Foods plant in Toronto.

The closed-door nature of her investigation has been a target of opposition critics, and yesterday was no exception as the Liberals called on the government to release the full, unedited report immediately.

Liberal agriculture critic Wayne Easter remains disappointed Weatherill does not have the mandate to find anyone criminally or civilly liable, but said that based on discussions with people who have been interviewed he expects “extensive recommendations on improvements to the food safety system.”
