Cheese producers, consumer groups, and health experts are raising the alarm about proposed federal regulations that could change the way cheese is made in Canada.

New rules being considered by the Canadian Food Inspection Agency could require cheese makers to use more liquid raw milk and less skim milk powder or whey.

That's infuriated cheese makers, who say the new regulations are nothing more than a political ploy to please dairy farmers. The new rules would benefit dairy farmers because cheese makers would have to buy more milk.

Don Jarvis of the Dairy Processors Association of Canada says that "the proposed changes would increase our costs so much that our productivity would be cut by about 20 to 25 percent."

But higher prices for some cheeses aren't the only thing worrying producers and retailers. They say if they can't add skim milk powder or whey to some of their lower fat cheeses, they'll have to add higher fat milk.

According to Rosie Schwartz, a dietician and author, the proposed rules would not just raise the cost of some cheeses. They would also lessen the health benefits of lower fat cheeses.

"I think that Canadians will not have access to affordable and tasty lower-fat cheese products, and with the epidemic of obesity and heart disease, it's a real concern," said Schwartz.

Cheese producers, retailers, and health experts aren't the only groups worried about the proposed changes. Restaurant owners say the proposed changes are too radical, and consumer groups are worried that customers will pay more and get less.

Manufacturers are also worried about the impact the new rules could have on Canada's trade with foreign countries. They fear a backlash abroad if foreign cheese producers face tougher obstacles getting their products into the Canadian market.

"It appear to be a clear attempt to create trade barriers," said Jarvis. "Our concern is that there will be major trade disputes with our trading partners, the Europeans and Americans."

Canada's cheese controversy has already raised international concerns. Some foreign cheeses may not meet the proposed federal requirements and that has raised concerns abroad. Denmark, Australia, and the European Commission are keeping a close eye on Canada's proposed cheese standards. They've already warned Ottawa that if it changes the rules, Canada may face trade sanctions.
