Hank McKinnell, chairman and CEO of chemicals group Pfizer, said he was not aware that any bids had been received for the Adams mint and chewing gum subsidiary. UK confectionery and soft drinks group Cadbury-Schweppes is hotly tipped to be finalising a bid after losing out on the sale of Hershey Foods last week. Cadbury had submitted a joint bid with Swiss giant Nestlé, which would in any case have been rejected in favour of a bid from US gum maker Wrigley had the sale of Hershey gone ahead.
