A report in the French financial weekly Challenges had suggested that Danone was considering a significant acquisition as a means of protecting his group against takeover attempts, and could be looking at a bid for Numico.
The speculation was fuelled by Natexis Bleichroeder analysts after a private visit to Danone, the report said.
However, a spokesperson from each company confirmed to Reuters this morning that there were no takeover discussions between the two firms.
"Danone is not making an offer for Numico," a spokeswoman told the news serivce.
Numico's head office also confirmed it was not in talks with Danone over a potential takeover.
