http://www.bloomberg.com/apps/news?pid=20601087&sid=a1cxaMCjP.mI&refer=home July 13 (Bloomberg) -- Canada said tests confirmed the nation's seventh case of mad-cow disease in a 50-month-old dairy animal born after feed restrictions were imposed in 1997 to curb the spread of the ailment .
Inspectors are tracing other cattle born on the same farm, the Canadian Food Inspection Agency said today in a statement. The government announced July 10 that the Alberta animal might be infected, pending further tests on tissue samples.
The announcement comes less than two weeks after Canada found its sixth case of the disease, which cattle contract by eating feed tainted with parts of an infected animal and which has a rare and fatal human form.

The CFIA last month tightened its animal feed restrictions to speed up eradication in Canada of mad-cow disease, or bovine spongiform encephalopathy.
