ITEM 8.01         OTHER EVENTS

     On June 28, 2006, the United Kingdom Office of Fair Trading ("OFT")
announced that it had referred to the United Kingdom Competition Commission (the
"Competition Commission") the acquisition by our subsidiary, Stericycle
International, LLC, in February 2006 of all of the stock of The Sterile
Technologies Group Limited, an Irish company providing medical waste management
services in Ireland and the United Kingdom.

     Under the terms of the OFT's referral, the Competition Commission is to
decide whether, as a result of this acquisition, there has been or is expected
to be a substantial lessening of competition in one or more markets in the
United Kingdom for healthcare risk waste treatment and disposal, and if so, what
remedial or other action, if any, should be taken or recommended by the
Competition Commission. According to the OFT, the Competition Commission is
expected to report in December 2006.
