Canadian media representations of mad cow disease.

A Canadian case of bovine spongiform encephalopathy (BSE) or "mad cow disease" was confirmed in May, 2003. An in-depth content analysis of newspaper articles was conducted to understand the portrayal of BSE and variant Creutzfeldt-Jakob disease (vCJD) in the Canadian media. Articles in the "first 10 days" following the initial discovery of a cow with BSE in Canada on May 20, 2003, were examined based on the premise that these initial stories provide the major frames that dominate news media reporting of the same issue over time and multiple occurrences. Subsequent confirmed Canadian cases were similarly analyzed to determine if coverage changed in these later media articles. The results include a prominence of economic articles, de-emphasis of health aspects, and anchoring the Canadian outbreak to that of Britain's crisis. The variation in media representations between those in Canada and those documented in Britain are explored in this study.
