WHITE PLAINS, N.Y., January 24, 2008 — The Dannon Company, Inc. today provided the
response below to a class-action lawsuit filed yesterday in Los Angeles, CA.

Dannon is aware of the lawsuit and we are reviewing it. Dannon proudly stands by the claims
of its products and the clinical studies which support them. All of Dannon’s claims for Activia
and DanActive are completely supported by peer-reviewed science and are in accordance
with all laws and regulations. Dannon’s advertising has always been and will continue to be
absolutely truthful, and Dannon will vigorously challenge this lawsuit.

Dannon strongly disagrees with the allegations in the lawsuit. The filed complaint does not
contain any support for the broad generalizations made in the lawsuit. The one publication
cited in the lawsuit does not disprove Dannon’s scientific substantiation for its proven product
benefits. Indeed, the report cited in the lawsuit, published by the American Academy of
Microbiology, does not even reference any Dannon products.

Dannon makes all scientific studies about its products available to the public following the
established method of peer-review and publication. Dannon regularly consults with leading
independent experts in the field of probiotics about the science behind all of its probiotic
claims.

The scientifically substantiated benefits of Dannon’s products are confirmed not only by the
scientific journals that have reviewed and published the findings - which are made available
on the company’s web sites for any and all to read - but also by the millions of highly satisfied
consumers who enjoy Dannon’s products.
