Is Canada's food safe?

A CBC News examination of Canada's food safety record over the last decade reveals mixed results.

A decade ago, nearly 1,200 cases of E.coli per year were reported by the provinces.

The number shrunk to 428 in 2011, according to the Public Health Agency of Canada.

But illnesses from salmonella are much higher in absolute terms.

Last year, public health officials reported 6,800 cases and 6,200 cases were reported in 2002.

Eight years later, the number jumped to 7,200, pointing to an upward trend.

Calgary father on dealing with E. coli

Robert Boschman's daughter, Christie, was three years old when she got E. coli poisoning.

Boschman, an English professor at Mount Royal University, was out of town when he received a "hysterical" phone call from his then wife, Tracy.

Their daughter Christie was at the Alberta Children's Hospital with acute bloody diarrhea.

When he arrived at the hospital, Christie was lying on a gurney as white as a ghost.

Luckily for Christie, the hospital was testing an experimental drug called Synsorb. Doctors gave her the drug and within 24-hours she was feeling better.

"We felt like we had just dodged a massive bullet," says Boschman.

However, almost immediately following that hospital visit, the Boschman's were back after their other daughter Nina, also contracted E. coli poisoning.

"I watched Nina and by this time, I was experienced enough to do a little counting, so I counted how many times Nina went to the bathroom in the first 48 hours," he told CBC News.

Report highlights extent of problem

Boschman's daughters contracted E. coli poisoning in 1999 — the same year the U.S. Centers for Disease Control and Prevention released a report on food borne illness that allowed North Americans to learn the scale of the food safety problem.

The study concluded that 76 million people got sick and 5,000 died each year in the U.S. from food pathogens, such as E. coli and salmonella.

Chris Boulton, who works for a Calgary lab that tests for food-borne pathogens in water, says Canada does have a good reputation for accuracy when it comes to tracking E. coli.

"Canada has been chastised by the Center for Disease Control, and even by provincial health associations that they're under, [for] reporting food-related illnesses. Unlike other industrialized nations, we're very inept at tracking these cases," said Boulton, the head of Benchmark Laboratories.

Experts also caution there are questions about how Canada reports food safety numbers.

The Canadian Medical Association suggests that only one in 200 cases of food-borne illness are actually reported.

The Canadian Food Inspection Agency itself says 11 million Canadians get sick every year from food-borne diseases.

High number of E. coli cases in Canada

Even though Canada's E. coli numbers have dropped, a working paper written by Denis Curtis at the University of Guelph shows that Canada has the highest reported rate of E. coli cases amongst nations in the Organisation for Economic Co-operation and Development.

Over the past decade, Canada reported 3.54 E. coli cases per 100,000 people — more than twice the rate of the United States.

Canada's high numbers are in part because of the Walkerton, Ont., E. coli outbreak in 2000.

But Sylvain Charlebois — one of the co-researchers on the Curtis working paper — cautions Canada's numbers are high, despite the high-profile Ontario outbreak that killed seven people.

"If you take out Walkerton, you're seeing a trend upwards of E. coli cases and it's very difficult to explain right now why that is, so we need to further investigate," says Charlebois.

Experts say one of Canada's key problems is traceability — tracking food from farm to fork.

Canada regularly ranks near the bottom of the developed world in our ability to track food through the food chain.

Change to food safety system needed, says expert

Charlebois suggests a systemic change to Canada's food safety system would help mitigate the problem.

Under the current regulatory system, Agriculture Canada oversees both the agriculture industry and food safety.

The minister of Agriculture is responsible for protecting both the agriculture industry and consumers.

Charlebois says there is an inherent conflict in that system.

"Sometimes these two mandates conflict with each other," he told CBC News.

"Which is why some other Commonwealth countries, we have parliaments dissecting both roles, [create] an independent agency focusing solely on food safety issues."
