Commodities and Agriculture: 'Mad cow' disease spreads to antelopes
THE CONDITION known in cattle as 'mad cow disease', spongiform encephalopathies, has been found in Britain's sparsely-scattered antelope population, the government has admitted. Three elands, three greater kudu and an arabian oryx have been diagnosed with the disease over the past three years. In all, six species other than cattle have been confirmed with the condition during this period. The statistics - released in response to a written question from Mr Ron Davies, a Labour agriculture spokesman - show a disconcertingly rapid increase in the number of sheep found to have the disease. A total of 894 cases of sheep encephalopathies or 'scrapie' were diagnosed in 1991, versus just 348 a year-earlier. However, the government states in a footnote to the table that the reporting of scrapie in sheep has been encouraged since 1991 'to obtain material for spongiform encephalopathy research'. Since 1989, the condition has also been confirmed in 23 cats and 29 goats. Mr David Maclean, junior agriculture minister, stressed that naturally occurring spongiform encephalopathies in species other than cattle were not notifiable diseases. He said there was 'insufficient epidemiological data' to 'draw firm conclusions' as to how the disease might have been contracted in cases other than scrapie. Scrapie, he said, was considered to be transmissible 'both maternally and horizontally'.
