EXHIBIT 99.1


                                VOTING AGREEMENT

     This Agreement is entered into as of October 19, 2002 by Stericycle, Inc.,
a Delaware corporation ("Parent"), Sharps Acquisition Corporation, a Delaware
corporation and wholly owned subsidiary of Parent ("MergerSub"), and Robert P.
Scherer, Jr., a Georgia resident ("Stockholder").

                                   Background:

     A. Stockholder is a significant stockholder of Scherer Healthcare, Inc., a
Delaware corporation ("Company"). He directly owns 493,983 shares of Company
Common Stock, par value $0.01 per share (the "Direct Shares"), and is the sole
stockholder, director and officer of RPS Investments, Inc. ("Holding Company"),
which owns 1,224,235.5 shares of Company Common Stock (the "Indirect Shares").

     B. In addition, Stockholder is the sole trustee of a voting trust for the
benefit of his adult children (the "Voting Trust"), which was established under
that certain Voting Trust Agreement, dated February 23, 1997, by and among
Robert P. Scherer, III, Lesley E. Scherer Reeves, Stephen M. Scherer and Mark C.
Scherer and which owns 562,739.5 shares of Company Common Stock (the "Voting
Trust Shares"). Stockholder is also a co-trustee, with shared voting power, of a
trust (the "Irrevocable Trust"), which owns 340,212 shares of Company Common
Stock (the "Irrevocable Trust Shares").

     C. The Direct Shares, the Indirect Shares, the Voting Trust Shares and the
Irrevocable Trust Shares together represent approximately 60% of the 4,390,264
shares of Company Common Stock issued and outstanding as of the date of this
Agreement.

     D. Concurrently with the execution of this Agreement, Parent, MergerSub and
Company have entered into an Agreement and Plan of Merger, dated October 19,
2002 (the "Merger Agreement"), pursuant to which Parent will acquire all of
Company's outstanding capital stock for cash through a merger of Company with
MergerSub (the "Merger").

     E. Company's board of directors, based upon the unanimous recommendation of
a special committee of its board of directors, has resolved to recommend that
Company's stockholders of Company approve the Merger Agreement and the
consummation of the Merger.

     F. Parent and MergerSub would not have entered into the Merger Agreement
without the voting and other assurances provided by Stockholder in this
Agreement.

     Now, therefore, in consideration of their mutual promises, and intending to
be legally bound, the parties agree as follows:
