On October 29, 2003, Charles River Laboratories International, Inc. issued a
press release providing financial results for the fiscal quarter ended September
27, 2003. The press release, attached as an exhibit to this report, includes
"safe harbor" language pursuant to the Private Securities Litigation Reform Act
of 1995, as amended, indicating that certain statements about Charles River's
business contained in the press release are "forward-looking" rather than
historic. The press release also states that these and other risks relating to
Charles River are set forth in the documents filed by Charles River with the
Securities and Exchange Commission.



Pursuant to the requirements of the Securities Exchange Act of 1934, as amended,
we have duly caused this report to be signed on its behalf by the undersigned
hereunto duly authorized.
