On 26 January, the group announced its intention to close operations at its Whitchurch site in Shropshire, citing "over-capacity within the UK meat industry and a very competitive marketplace" as well as "cheaper sources of raw material" from abroad.
Steve Crozier, pork division managing director, said: "Due to these increasingly competitive pressures, we anticipate a significant reduction in the volumes of products manufactured through the Whitchurch site. As a consequence of the review of our manufacturing operations, the company is proposing to close its operations at Whitchurch, resulting in the possibility of redundancies.
"We regret the need for this change in our activities, announced today, and have informed our employees and their Union representatives of our commitment to consult with them," he added.
The company will be consulting with the 87 workers to see if the redundancies can be avoided, including trying to find jobs for them either within the business or with other local companies.
This comes after Grampian confirmed 60 jobs are to go at its Suffolk plant at Haverhill. The announcement follows 40 redundancies six months ago at the same plant, cutting numbers from its 900-strong workforce.
Eric Winter, head of human resources at the Haverhill plant, said: "We have given notification of up to 60 redundancies to take place between the beginning of February and the end of May this year. This is part of our overall strategy to make the site more competitive in the marketplace."
