The U.S. government is considering new regulations that would continue to protect consumers and the meat industry from bovine spongiform encephalopathy, better known as "mad cow disease."
In the Jan. 17 Federal Register, the Food Safety and Inspection Service of the Department of Agriculture requested public comments and data on the potential costs, benefits and feasibility of its proposed measures.
Among potential policy options:
- limiting human consumption of the potentially most infectious portions from cattle, including spinal cord tissue and brain. These parts are considered a delicacy by some ethnic groups and are popular in England;
- prohibiting use of central nervous system tissue in boneless beef products, such as hot dogs and other processed meats, and use of intestines for natural sausage casings;
- restricting use of meat from mechanized advanced meat recovery systems, a mechanized production process;
- prohibiting use of spinal columns from certain cattle, including unhealthy animals that can't walk.
"We're constantly learning more about BSE from countries that have it, and these ideas are similar to theirs," said Carol Blake, spokeswoman for the FSIS. "It's up to industry to decide if they want to comply now."
Meat industry officials, however, are likely to resist any regulatory proposals. The American Meat Institute, the Arlington, Va.-based trade association for meat and poultry packers and processors, considers the new options unnecessary.
"There's no reason to place these limitations because there's no BSE in this country," said spokeswoman Janet Riley. "The existing triple firewall of animal import controls, feed controls and aggressive surveillance means we're unlikely to get it. Placing costly limitations on very safe products is probably premature, since they could be implemented very quickly if needed."
Last year, the AMI countered calls to curtail AMRS use on back and neck bones. It "will increase the potential for worker illness and will waste millions of pounds of nutritious meat," AMI said in a statement last August.
The American red meat industry rang up $80 billion in sales in 1997, according to the most recent data from the Department of Commerce.
An industry expert praised the USDA for taking on the task of considering new regulations. "It's a very prudent step to put it up for discussion," said Will Huston, DVM, Ph.D., director of the center for animal health and food safety at the University of Minnesota, St. Paul. "If we never get BSE, people will ask why we spent money on this. If we see BSE, we'll be criticized for not taking more aggressive actions. It's pragmatic and wise to evaluate measures and their impacts even if they're never implemented."
The USDA places no time limit on accepting public comments. Consequently, any new federal regulations will take years to develop and formalize. The USDA has an emergency plan in place just in case BSE appears.
Study Shows Low Risk
A three-year Harvard University study, released Nov. 30, 2001, concluded that the United States is highly resistant to the introduction of BSE. Existing measures taken by government and industry provide effective controls that would minimize the spread of BSE to animals and humans if it were introduced to the country's food chain.
To prevent an outbreak, the Food and Drug Administration has repeatedly advised manufacturers to purchase animal tissues or components only from countries where BSE does not exist.
"It's up to manufacturers to make sure sources don't contain BSE elements," said an FDA representative, who declined to be identified. "Dietary supplements and cosmetics containing bovine materials from animals originating in the 31 countries where BSE has been found, or that pose a risk of its being found there, are excluded from the United States. The FDA requires that gelatin-containing products, such as candy or capsules, imported from countries identified as having risk for BSE, be manufactured under specific guidance and certified to ensure they are safe for American consumers."
Keeping America Clean
Although it may be possible for infected animals to transmit BSE through transfusions or pregnancy, the main cause appears to be animal feed containing remains of infected animals. The USDA, FDA and Centers for Disease Control and Prevention have worked with the meat industry to keep out BSE. Prior measures include prohibiting mammal protein in feed processing; banning cattle imports, their by-products, and other animals from known trouble spots; and inspecting suspect animals before slaughter. In 2000, the FDA and USDA banned imports of rendered animal proteins from 31 countries, and began to allow inspectors to detain shipments from these countries.
"Milk and milk products are still imported from these countries because they are not believed to pose any risk for transmitting BSE to humans," said an FDA spokesman.
The prevention system, however, is not perfect. Between 1998 and 2000, the FDA conducted nearly 10,000 inspections in the United States of companies involved in the processing, distribution and use of animal feed. It found that almost one-fourth were not in compliance with current standards. Less than 85 percent of the 180 renderers handling prohibited materials were in compliance. The FDA is conducting additional inspections of noncompliant facilities.
The World Health Organization notes that milk and milk products are considered safe, but advises removal of lymphatic and nervous system tissue from meat, and avoidance of any tissue that may come from deer or elk, domestic or wild, with any illness.
