"It is all very laudable to attempt to prevent the risks of BSE at Community level today, but it was almost 15 years ago that our researchers clearly established that one of the causes of mad cow disease was the consumption of cattle fodder containing animal-based meal made from ingredients taken from the carcasses of sheep suffering from ovine scrapie."
Que l' on se soucie aujourd' hui de prévenir au niveau communautaire les risques d' ESB est louable, mais cela fait maintenant près de 15 ans que nos chercheurs ont clairement établi que l' une des origines de la maladie de la vache folle était la consommation d' aliments pour bétail contenant des farines animales dont la composition incluait des cadavres d' ovins atteints de la tremblante du mouton.
