Class 24: Mad Cow Disease


Read "British Researchers Link 10 Brain Infection Cases" from the Washington Post, "
Why we won't take the risk" by Robert Matthews in the Sunday Telegraph, and "Britain's Daunting Propsect: Killing 15,000 cows a week" from the New York Times about Creutzfeldt-Jakob Disease (CJD).

The population of Great Britain is about 58,000,000. How many cases of CJB would you expect in a year? Why is everyone so concerned about these 10 cases? Should they be?

What do you think of Robert Matthews independence argument?

How small would the odds of catching CJD from eating beef have to be for you to think no action should be taken by the British government? Linda is considering becoming vegetarian. How big would the odds have to be for you to turn vegetarian?

The New York Times article says that the stringent enforcement of the regulations (concerning animal feed) has paid off. What are other possible explanations for the smaller numbers of cases of mad cow disease for cows with later birth years?

Do you think Great Britain is justified in killing all cows over 30 months old?
