Warnings that the very young, the elderly, pregnant women and those with compromised immune systems are particularly at risk appeared Saturday in newspapers across the country - some 10 days after the first death was reported.

The ad provided advice on safely handling food, and advised checking a government list of recalled products.

And Maple Leaf took out full-page ads in which president Michael McCain said it was the company's expectation that all recalled products had been removed from store shelves.

On Friday, the number of deaths conclusively blamed on the outbreak grew by one to nine as officials confirmed a death in British Columbia from the outbreak - the first death to be reported outside of Ontario.

Six other deaths - four in Ontario and one each in Saskatchewan and Quebec - remain under investigation for possible links to the outbreak.

It's been nearly two weeks since the original recall was announced, and yet an additional 50 products were added Friday to an expanding list of recalled items because they may contain contaminated product.

It may not be over yet, Agriculture Minister Gerry Ritz told a news conference.

"Well, the recalls, there'll be a few more as we get out into the secondary processors and some of the third line," Ritz said during a news conference in Ottawa.

"Some of this product went out somewhere and other sandwiches were made out of it, that's the nature of the recalls as they grow."

Officials stressed that the continued recalls were a symptom of Maple Leaf voluntarily removing hundreds of products from the marketplace that, although they haven't tested positive for the Listeria bacterium, were made at the same plant where the tainted meat was discovered.

"The most important information for consumers is, as we go out there we are providing further precision that informs them and lets them recognize these products in ways they weren't able to do with the initial recall," said Dr. Brian Evans of the Canadian Food Inspection Agency.

The agency added a variety of ready-to-eat products early Friday that are sold in Sobeys and Foodland stores throughout Atlantic Canada, including hospitality and party trays.

The spectre of continued recalls this long after the initial public health warning is "very disconcerting," said Christina Bisanz of the Consumers Council of Canada.

"It certainly does shake the confidence of consumers to know that it's taking this amount of time," Bisanz said. "It just demonstrates that our need to make sure that we have absolute vigilance throughout this process is paramount."

The mayor of Walkerton, Ont. - the scene of a deadly E. coli disaster eight years ago - called for a public inquiry.

Charlie Bagnato said he's "shocked" the federal government hasn't learned the lessons of his town's tainted-water tragedy in 2000, which killed seven people and made thousands more ill.

Bagnato noted that three federal ministers - Tony Clement, John Baird and Jim Flaherty - were all members of the Ontario cabinet at the time of the Walkerton outbreak.

The Walkerton tragedy was a result of government deregulation and cost-cutting, said Bagnato, who added he fears the federal Conservatives may be on the same track.

Bagnato said his concerns were further fuelled by media reports Friday that the Harper government opposed tougher U.S. rules to prevent Listeria, namely daily inspection visits and testing products for the Listeria bacterium.

NDP Leader Jack Layton said he intends to raise the issue when he meets Saturday with Prime Minister Stephen Harper. The meeting is intended to help Harper, who is poised to call an election next week, judge whether there's any chance of a productive fall session of Parliament.

But Layton told The Canadian Press he intends to add an item to the agenda: "To insist (Harper) take immediate action to put inspectors on the floor of meat processing plants."

Layton said such a step is necessary "to very quickly restore the confidence of Canadians and, more importantly, to protect Canadians."

Officials in Ottawa defended their position, saying Canada's approach produces "equivalent outcomes."

"In the U.S. they had a legislated commitment to visit the plants daily," said Paul Mayers, a food inspection official.

"We took a different approach originally, which meant that those tasks were applied by the inspectors spending more time in the plants, though not necessarily on a daily basis."

Meanwhile, health officials in Quebec recalled three cheese products amid an outbreak of salmonellosis that has killed one person and sickened 87 in several parts of the province.

The news came just days after the province's Food and Agriculture Department recalled Quebec-made cheese that tested positive for Listeria - a different strain than the one that's responsible for the larger national outbreak.

The two outbreaks are not linked, Horacio Arruda of Quebec's public health department said Friday.

Arruda said that in one week this month there were as many salmonellosis cases reported in the province's Eastern Townships as there are in an average year.

Earlier Friday, Ontario's top medical official said the Listeria outbreak might have gone unnoticed if not for the health-tracking system put in place after SARS.

Dr. David Williams, the province's acting chief medical officer of health, said the outbreak would have been "very hard" to spot under the old, paper-based system because the listeriosis cases were spread throughout Ontario.

The SARS outbreak in 2003, which claimed 44 lives in Canada, led to a revamp of how Ontario public health units report to the province.

Reportable diseases are now entered into an integrated computer database that Williams said allowed the relatively small jump in listeriosis cases over the summer to trigger an investigation.

"With our system, we were able to pick it up with relatively small numbers, otherwise it might have gone unnoticed," Williams said.

"It helped us to connect the dots in such a way that we were able to say we have something provincially going on."

The recalled products sold in the Atlantic Canada Sobeys and Foodland stores also included submarine sandwiches and wraps and have best-before dates up to and including Aug. 25, 26 and 27.

The agency also recalled 10 sandwiches containing turkey which were made and sold in Ontario at Loblaws, Loblaw Superstore and Real Canadian Superstore outlets. These items carry a best-before date up to and including Aug. 25.

Three varieties of submarine sandwiches made and sold at Loblaws and Provigo stores in Quebec were also added to the list, in addition to four products sold in Quebec at IGA, Bonichoix, Tradition and Omni stores.

Another seven products sold at Sobeys and IGA outlets in B.C., Alberta, Manitoba and Saskatchewan were also added, with best-before dates up to and including August 26.

On Friday night the CFIA and Metro-Richelieu Inc. of Montreal recalled several ready-to-eat deli meats, vacuum packed in stores, because the meats were products recalled by Maple Leaf.

The meats - ML or Maple Leaf Waxed Bologna and ML or Maple Leaf Regular Bologna, BI or Bittners Oven Roast Turkey Breast with a best before date of 05 SE 2008 - were sold in certain Metro, Richelieu, Ami and Gem stores in Quebec.

Reduced Cold Cut Ends packaged in clear, vacuum plastic bags of various weights with best before dates up to and including Aug. 27 sold at some A&P, Dominion, Loeb and The Barn stores in Ontario.
