CNS (Central Nervous System) Testing

The Central Nervous System (CNS) test was developed to meet the needs of beef and pork plants using an Advanced Meat Recovery (AMR) system to separate meat from the bone. 

This test helps slaughterers and processors verify their compliance with the FSIS directive 7160.3 requiring zero presence of spinal cord tissue in finished products. 

In an interim final rule announced December 30, 2003, establishments have to ensure process control through verification testing to ensure that neither spinal cord nor dorsal root ganglia is present in the product.

FSIS Regulatory Sampling Program

On March 3, 2003 the "FSIS began a routine regulatory sampling of beef products from AMR systems as outlined in a December directive. FSIS' new sampling program requires inspectors to test beef product from AMR systems on a routine basis to verify that spinal cord tissue is not present. If spinal cord tissue is detected, action will be taken to relabel held product or recall distributed product from commerce. Inspection personnel also will conduct follow-up sampling to verify that the establishment has taken appropriate corrective action. AMR production will not be allowed to resume until FSIS determines that those corrective actions have been successful." http://www.fsis.usda.gov/OA/news/2003/amrsampling.htm

The directive was updated on December 30, 2003 (Release No. 0452.03) after a BSE infected cow was detected in the United States.

"In an interim final rule, FSIS will require federally inspected establishments that slaughter cattle to develop, implement, and maintain procedures to remove, segregate, and dispose of these specified risk materials so that they cannot possibly enter the food chain. Plants must also make that information readily available for review by FSIS inspection personnel."
Release No. 0452.03 USDA BSE Update, December 30, 2003

Advanced Meat Recovery (AMR)

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.

Routine validation can help you assure that your procedures are complying with the FSIS directive. Silliker, Inc. utilizes the R-biopharm ELISA (Enzyme-Linked Immunosorbent Assay) to detect the presence of GFAP (Glial Fibrillary Acidic Protein) found in spinal cord tissue in or on meat with a detection limit of approximately 0.1%.
