Canada confirms its second case of BSE

30 January 2007

US - Canada has confirmed its second case of BSE. The affected dairy cow was born in the province of Alberta, just like the only other cases of mad cow disease discovered in North America: one in Canada in 2003 and one in the US in the same year.
Also like the previous cases, the infected cow was born and probably infected before 1997. This was the year when feeding cattle with the remains of other cattle, a practice that spreads BSE, was banned in North America.

The discovery highlights concerns about surveillance for BSE in the US. The infection probably arrived with cattle imported from the UK in the 1980s. Normal patterns of animal and feed movements should have spread it across the continent since then.
