OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at

Dear Mr. Jochum:

Thank you for your letter of August 28 requesting a written clarification of appropriate recordkeeping practice for CTD case resolution and symptom recurrence.

This letter is to verify as stated in the Ergonomics Program Management Guidelines For Meatpacking Plants, 1990, that a case is considered to be complete once there is complete resolution of signs and symptoms for a thirty day period. If complaints reoccur within that thirty day period, you may consider it a continuation of a previous case rather than a new case.

If you have any questions or comments please contact Bob Whitmore of my office at (202) 523-1463.
