USDA Bans Use of 'Downer' Cattle as Food

Takes several other steps to control mad cow disease

By Robert Longley, About.com

Advanced Meat Recovery. AMR is an industrial technology that removes muscle tissue from the bone of beef carcasses under high pressure without incorporating bone material when operated properly. AMR product can be labeled as “meat.” FSIS has previously had regulations in place that prohibit spinal cord from being included in products labeled as “meat.” The regulation, effective upon publication in the Federal Register, expands that prohibition to include dorsal root ganglia, clusters of nerve cells connected to the spinal cord along the vertebrae column, in addition to spinal cord tissue. Like spinal cord, the dorsal root ganglia may also contain BSE infectivity if the animal is infected. In addition, because the vertebral column and skull in cattle 30 months and older will be considered inedible, it cannot be used for AMR.

In March 2003, FSIS began a routine regulatory sampling program for beef produced from AMR systems to ensure that spinal cord tissue is not present in this product. In a new interim final rule announced today, establishments have to ensure process control through verification testing to ensure that neither spinal cord nor dorsal root ganglia is present in the product.

Air-Injection Stunning. To ensure that portions of the brain are not dislocated into the tissues of the carcass as a consequence of humanely stunning cattle during the slaughter process, FSIS is issuing a regulation to ban the practice of air-injection stunning.

Mechanically Separated Meat. USDA will prohibit use of mechanically separated meat in human food.

On Dec. 23, Veneman reported that a cow in Washington State has tested positive for BSE. A swift and comprehensive investigation is ongoing to trace the animal to a herd of origin, which is believed to be located in Alberta, Canada, as well as track additional animals that have entered the United States. (For the latest update on the investigation, visit www.usda.gov.)

For more than a decade, the United States has had in place an aggressive surveillance, detection and response program for BSE. The United States has tested over 20,000 head of cattle for BSE in each of the past two years, 47 times the recommended international standard.

Since 1989, USDA has banned imports of live ruminants and most ruminant products from the United Kingdom and other countries having BSE.

In 1997, the FDA prohibited the use of most mammalian protein, the main pathway to spread the disease should it be in the United States, in the manufacture of animal feed intended for cattle and other ruminants.

An independent analysis by Harvard in 2001 and again in 2003 shows that the risk of BSE spreading in the United States is low and any possible spread would have been reversed by the controls we have already put in place.
