The Saskatchewan government says it's disappointed the United States hasn't removed Country of Origin Labelling from a new farm bill.

Saskatchewan claims the labelling, which goes by the acronym COOL, has cost Canadian cattle producers $1 billion annually since 2008.

The labels tell shoppers in the U.S. when the meat they buy is from a Canadian-born cow.

Proponents of COOL say it's about food safety and consumer awareness, but critics say it's simply protectionism.

Saskatchewan Trade Minister Tim McMillan said in a news release the province is encouraging the federal government to move ahead with retaliation.
