Test 'em all

As anxiety about mad cow disease grows in mainland Europe, the European
Commission says it will ask all member states to carry out a BSE test on every
slaughtered cow over a certain age. The age will be decided later. The European
Union has already decided to test some 170,000 cattle, mainly those that have
died for unknown reasons, starting next year. Similar tests in France have
revealed much more infection than expected, suggesting that there could be more
BSE in Europe than authorities suspect.
