As the true depth of the BSE
epidemic comes to light in Europe, just-food.com has compiled a global
calendar of events connected to the spread of the disease.
It is widely argued that
the crisis unravelled after changes were made to the production of cattle feed
during the 1980s. The process of rendering, using animal remains in feed, has
been widespread since the 1920s, however scientists believe that due to changes
such as a ban on the use of solvents and lower temperatures during manufacture
over 60 years later, a strain of the sheep disease scrapie found its
way into the cattle troughs.
This is how the crisis unfolded
and a concise guide to the measures implemented to deal with the disease across
the world, including action taken within the EU, in particular in the UK, and
in the US by the US Department of Agriculture/APHIS, the Food and Drug Administration
and the United States Livestock Industry:
