A Staffordshire sandwich maker investigated over the recent listeria outbreak at a number of hospitals has gone into liquidation.
Five patients died after being infected.
125 jobs will go at Stone based Good Food Chain, which has ceased trading with immediate effect.
40 agency staff were let go at the start of June when it voluntarily ceased production.
All all products were also withdrawn, after being linked with the outbreak.
The strain of listeria has since been identified in meat produced by North Country Cooked Meats, supplied by North Country Quality Foods, which was used by The Good Food Chain.
Earlier this week the Food Standards Agency confirmed The Good Food Chain was not the source of the outbreak, and had told the company it could resume production.
The firm released a statement saying it had not yet taken any decision about whether it is viable to do so.
But it has now said the impact on the company has been 'too great'.
The Good Food Chain was founded in 1996 by Martyn Corfield.
Today he said: “I was absolutely devastated to hear that people had died after contracting listeriosis and have been thinking constantly about all those affected and their families over the last few weeks.
“We have been co-operating very closely with the investigating authorities, and while Wednesday’s confirmation that the Good Food Chain was not the source of the outbreak was welcome, it ultimately came too late in the day for us to get the business back on to a sustainable footing.
“I feel desperately sorry for our brilliant and hardworking staff who, through no fault of their own, now find themselves out of work. I would like to thank them for everything they have done for the Good Food Chain, and particularly for their loyalty and patience over the last few weeks.”
