Mad Cow Disease: Improvements in the Animal Feed Ban and Other Regulatory Areas Would Strengthen U.S. Prevention Efforts

A letter report issued by the General Accounting Office with an abstract that begins "Bovine spongiform encephalopathy (BSE), also known as mad cow disease, has been found in cattle in 23 countries. Countries with BSE have suffered large economic losses because of declines in both beef exports and domestic beef sales. The U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA) have primary responsibility for preventing the introduction of BSE-contaminated cattle, beef, and cattle-derived products into the United States. GAO found that FDA has not acted promptly to force firms to keep prohibited proteins out of cattle feed and to label animal feed that cannot be fed to cattle. FDA's data on inspections are severely flawed, and FDA is unaware of the full extent of industry compliance. If BSE was discovered in U.S. cattle, many consumers might refuse to buy domestic beef; beef exports could decline dramatically as could sales in related industries, such as hamburger chains and frozen dinner manufacturers. Furthermore, some people might develop mad cow disease if infected cattle were to enter the food supply. The United States acted as many as five years earlier than did other countries to impose controls over imports of animals and animal feed ingredients from countries that had experienced mad cow disease. Similarly, U.S. surveillance efforts to test cattle brains for mad cow disease met internationally recommended testing targets earlier than did other countries. However, the United States' feed ban is more permissive than that of other countries, allowing cattle feed to contain proteins from horses and pigs. FDA is reviewing whether these ingredients should continue to be allowed in cattle feed. Finally, as in most countries that are BSE-free, cattle brains and other central nervous system tissue can be sold as human food.
