Mondelez International, which makes Oreo and Chips Ahoy cookies and Cadbury chocolate bars, poured funding into start-up Celleste Bio earlier this month, according to The Financial Times.

Other Cadbury products, such as Oreo Bites, Bitsa Wispa, and Crunchie Rocks, have also been impacted by reductions, with a 9% decrease in quantity, while the price of £1.75 per bag remains unchanged.
