Up to 66 jobs are at risk at a major food factory in Bury St Edmunds.
Workers at the Mizkan plant, in Mildenhall Road, which produces Branston Pickle and supermarket brand products, were told on Wednesday that cuts will be made.
Approximately 350 people are employed at the plant and there will be a 45 day consultation but bosses say there will be no job losses before Christmas.
The Japanese firm bought the factory from Premier Foods in a £92.5 million deal in October 2012.
Further roles could go at other sites in Middleton, Greater Manchester and Chiswick Park, London - taking the maximum number at risk to 87.
A spokesman said: “Mizkan Euro is currently undergoing a business restructure. Challenging environmental conditions within the UK food market have meant that a streamlining of processes, and implementing cost reductions, at Mizkan sites has become essential.
“A maximum of 66 roles are affected at the Bury site. Employees have been informed of the potential redundancies. A period of formal consultation will follow.
“The restructure will not affect the organisation’s manufacture or distribution of any of its products, including all products within the Branston, Sarson’s, Haywards ranges.”
In a letter to the company, outgoing Bury St Edmunds MP David Ruffley raised concerns about the move.
He said: “This is extremely disappointing for the local community and those who are likely to lose their livelihood.”
