MP Dan Norris is to meet with Kraft Foods executives to discuss the firm's takeover of Cadbury.
Mr Norris said he wanted to discover what implications the deal would have for Cadbury's Somerdale factory in Keynsham.
The plant was earmarked for closure under Cadbury plans. Kraft has said it wants to maintain production there.
Mr Norris, Labour MP for Wansdyke, will meet a senior representative from the company in private later.
The MP said: "At this truly critical time, as Kraft bosses turn their thoughts to the future of the Somerdale site, I want the new owners to be in no doubt about the great strength of local feeling and the hopes and fears of Keynsham people.
"As well as hoping to get a clearer idea of Kraft's plans for Somerdale, local people will understandably be anxious to know the American company's timescale for key announcements about the factory's future.
"Today's meeting is an important start in this process."
The Cadbury board advised its shareholders to accept Kraft's offer of £11.5bn on Tuesday.
Cadbury's UK chairman Roger Carr told the BBC earlier this week that he expected job losses at its head office in Uxbridge, London.
However, he added that he saw Kraft both supporting and developing Cadbury's UK production facilities.
