Canadian farmers will continue to feed cow’s blood to cattle despite a US assessment that such practice could spread mad cow disease.


The Canadian Ministry of Agriculture, said its scientific evidence indicates little risk
that blood could be infectious and will not prohibit it as feed, despite Washington’s urgings.


Some scientists say there is evidence that prions, the infective proteins that cause mad cow disease, can spread through blood.


Cow’s blood is used as a milk replacement for dairy calves that are separated from their mothers. Canada has banned feeding material from ruminants to ruminants, but it makes exceptions for blood, fat and gelatin.
