An emergency meeting has been held by councillors over the planned closure of the Hall’s of Broxburn meat processing plant.
The threat to 1700 jobs would have a “devastating” impact on the area, West Lothian Council said.
Plant owner Vion Food UK announced a 90-day consultation last week on proposals to close the site, which is losing £79,000 a day.
Councillors agreed to give the authority’s chief executive power to push ahead with whatever work is required to develop a case for safeguarding the plant and jobs.
The factory employs 1150 permanent and 595 agency staff. It is a major processing facility for Scottish pork, handling about 8000 pigs each week.
After yesterday’s meeting in Livingston, council leader John McGinty said: “The council’s focus is on Vion retaining jobs at the Broxburn plant. We have asked for a full explanation of how this situation came about and we are pressing Vion to ensure that every option is fully explored.
“The major objective for all concerned must be to safeguard the future of the plant.”
The council is writing to First Minister Alex Salmond, as well as the company and a union, to express its concerns.
