OTTAWA, May 2 (Xinhua) -- The Canadian Food Inspection Agency (CFIA) announced Wednesday that a diary cow in the western province of British Columbia had died of mad cow disease.

    No part of the infected animal had entered the human food or animal feed system, the CFIA said.

    This is the 10th case of mad cow disease in the country since 2003, when the United States imposed an embargo on Canadian beef amid fears of mad cow infection.

    The CFIA said the six-year-old diary cow was infected in its first year of life, possibly by exposure to a small amount of infected material.

    The CFIA is now inspecting other animals born about the same time and is trying to find out how the infection happened.
