Estimated Compliance for Removal of Specified Risk Materials from 18 U.S. Beef Packing Plants

The removal of 18,345 specified risk materials was observed during audits of 18 U.S. beef processing facilities that, in total, account for over 90% of total U.S. beef slaughtered. Audited plants varied in capacity (280 to 6,000 head per day) and processed both “fed (young cattle)” and “nonfed (mature cows/bulls)” cattle. When all observations for removal of specified risk materials were combined from plants and adjusted for type of cattle processed, overall compliance with specified risk material removal regulations was 98.08%. A 100% compliance rate for removal of brains and distal ileums was recorded based on a total of 600 observations for removal of brains and a total of 2,400 observations for removal of distal ileums. Observations for removal of dorsal root ganglia were collected from 16 of the 18 plants, and overall compliance for dorsal root ganglia removal was 99.6% (4,783 of 4,800). Fifteen of the 16 plants were 100% compliant. For tonsils, data from 18 plants were collected, and tonsils were correctly removed from 92.8% (4,777 of 5,145) of tongues and heads. Data for spinal cord removal were collected from 18 plants, and the spinal cord was removed completely in line with U.S. Department of Agriculture–Food Safety and Inspection Service regulations for 99.43% of the observations. Based on the results of this study, packing plants have demonstrated that they are complying with regulations for removal of specified risk materials from beef meat products intended for human consumption greater than 98% of the time. To continue to assure food safety and consumer confidence, continued vigilance and provision of training programs for plant workers are essential.

For the article “Comparison of Immunochemical (Enzyme-Linked Immunosorbent Assay) and Immunohistochemical Methods for the Detection of Central Nervous System Tissue in Meat Products” by Hossner, K. L., R. S. Yemm, S. E. Sonnenshein, G. L. Mason, B. A. Cummings, M. C. S. Reddy, J. N. Sofos, J. A. Scanga, J. D. Tatum, G. C. Smith, and K. E. Belk, J. Food Prot. 69(3):644-650, the authors indicate the following. A typographical error was noted in the second column of p. 645 describing procedures associated with the F-ELISA: reference “(22)” is cited incorrectly and should be changed to reference “(16).” Secondly, an error of omission was noted. The study was completed during 2003 using a U.S. Department of Agriculture (USDA) Food Safety and Inspection Service (FSIS) immunohistochemical (IHC) protocol that was supplied to the researchers by the Agency (FSIS). The Agency subsequently archived that protocol and published a revised protocol (USDA-FSIS, 30 January 2004; Detection of Central Nervous System Tissue and Dorsal Root Ganglia in Beef and Central Nervous System Tissue in Pork Comminuted Meat Products by Histologic Examination of Hematoxylin and Eosin Stained Slides and Glial Fibrillary Acidic Protein Immunohistochemistry; SOP No: PLG 0001.01; available at: http://www.fsis.usda.gov/ophs/plg/plg0001.01.pdf) that differed in the criteria used for detecting dorsal root ganglia (DRG) for regulatory purposes and that was implemented in an Interim Final Rule published in the Federal Register on 12 January 2004. Our article should have acknowledged that the study was completed before the original IHC protocol was archived and the new protocol was implemented.
