Encephalopathy (BSE)

• Specified Risk Materials (SRMs)

2
Specified Risk Materials (SRMs)

• On January 12, 2004, FSIS published an interim
  final rule on Specified Risk Materials (SRMs) and
  requirements for non-ambulatory disabled cattle.
• SRMs only apply to cattle.
• Definition
• Specified Risk Materials are inedible and cannot
  be used in human food.

3
SRM Requirements

• Apply to all beef plants
• Federal
• State
• Custom-Exempt
• Imports

4
Specified Risk Materials (SRMs)

• In all cattle
• Tonsils
• Distal ileum of the small intestine
• Only the distal ileum is a Specified Risk
  Material, but the entire small intestine must be
  removed and not used for human food.

5
Identifying Age of Cattle for Slaughter

• One of a plants first activities should be to
  identify the age of cattle, because the SRMs are
  different for cattle 30 months of age and older.
• If the plant does not have records on the age and
  is not using dentition, it should handle all
  carcasses and parts as if they were from cattle
  30 months of age and older.

6
SRMs In cattle 30 months and older

• Brain
• Skull
• Eyes
• Trigeminal ganglia
• Spinal cord

7
SRMs In cattle 30 months and older

• Dorsal root ganglia (DRG)
• Vertebral column, excluding
• Vertebrae of the tail
• Transverse process of the thoracic and lumbar
  vertebrae
• Wings of the sacrum

Reasons for Prohibiting these Parts

• It is generally accepted that in animals with
  clinical BSE disease, the brain and spinal cord
  contain the greatest concentration of the BSE
  agent.
• Except for the skull and vertebral column, SRMs
  have demonstrated infectivity either in cattle
  naturally or experimentally.
• The skull and vertebral column are included
  because they contain the trigeminal ganglia
  (skull) or the spinal cord and DRG (vertebral
  column).

11
SRMs Plant Responsibilities

• Federal, State, and plants importing into the
  U.S. must
• Implement and maintain written procedures for the
  removal, segregation, and disposition of SRMs.
• Incorporate these procedures into HACCP Plans,
  Sanitation SOPs or other prerequisite programs.
• Have corrective action provisions.
• Custom-exempt plants
• Must comply with the adulteration provisions of
  the FMIA. (SRMs must be handled as inedible).

12
SRMs Plant Responsibilities

• Plants must
• Maintain daily records to document implementation
  and monitoring of procedures for the removal,
  segregation, and disposition of SRMs.
• Make these records available to FSIS inspection
  program personnel upon request.

13
Recommended Procedures

• If plants slaughter both young cattle and cattle
  30 months and older
• Recommend that young cattle be slaughtered first
• If cattle 30 months of age and older are
  slaughtered first, sanitize equipment and verify
  there is no cross-contamination of carcasses

14
Acceptable Procedures

• In cattle 30 months of age and older, after
  carcass-splitting
• Is acceptable to remove visible spinal cord with
  knife trimming.
• To clean equipment, utilize the provisions of 9
  CFR 416.

15
SRMs Plant Responsibilities

• Processing plants must
• Segregate/identify bone-in product from cattle 30
  months of age and older in order to properly
  address SRM removal and control.
• Recognize that T-bone or porterhouse steaks and
  bone-in rib roasts can no longer come from cattle
  30 months of age and older.

16
SRMs FSIS Responsibilities

• In addition to present inspection procedures,
  FSIS inspection program personnel will
• Verify the age of cattle.
• Verify the adequacy and effectiveness of a
  plants procedures regarding SRMs.
• Condemn the heads from cattle 30 months of age
  and older unless the plant can verify that the
  stunning does not result in brain leakage onto
  the head.

17
Additional Help

• FSIS wants to help all plants understand their
  responsibilities under the new rules
• That is why we are holding this series of
  Teaching Workshops and providing the workbooks.
• FSIS inspection program personnel are working
  closely with plants to help you understand and
  implement the new rules.

18
Additional Help

• The Strategic Initiatives, Partnerships and
  Outreach staff from the Office of Public Affairs,
  Outreach and Education (OPAEO) is working closely
  with FSIS District Offices, State Inspection
  programs, and the Contacts and Coordinators in
  every state to provide technical assistance to
  small and very small plants. [phone]
