Production at the Kellogg's factory in Greater Manchester has come to an end after almost 90 years, with the loss of about 360 jobs.

The site in Trafford Park was one of the largest cereal factories in Europe when built in 1938 but production is being transferred to the company's site in Wrexham, north Wales.

A spokesperson for owners Kellanova said the site has been a crucial part of its success for decades, adding: "We thank everyone who has worked there, as well as the suppliers, partners and local community who have worked alongside us."

Mick Murray from retail union Usdaw said it was "a sad time" after working to "try to secure the best possible outcome for our members".

In 2024 Kellanova announced that production of breakfast cereals would move to Wrexham, saying the investment required to maintain the factory was not viable.

It came after the end of three-month talks with union and employee representatives.

Marking the last week of production on site, a company spokesperson said: "A significant milestone was reached this week, as operations across production and packing came to an end."

They said their priority through the transition has been to "support colleagues and the wider community through this period of change".

Kellogg's is an American company founded in Michigan in 1906. It began exporting to the UK in 1922.

The cereal giant said the Trafford Park factory was laid out in a way that made sense in the 1930s, with food travelling up and down six floors in a legacy manufacturing process, the company previously said.

The site once produced a million boxes of breakfast cereal a day, including Corn Flakes, Rice Krispies and Coco Pops.

The company said half of the space in the Trafford Park building was unused and it would have cost too much to redevelop the site.

The site will remain open until the end of the year.

Kellanova said it would work with local partners to recognise and celebrate the site's legacy and would also continue to mark special milestones in the months ahead.

The firm continues to have a large footprint in the North West, with about 500 jobs remaining at its UK head office at Media City in Salford and at a distribution centre in St Helens.

Murray said Usdaw had worked to support members and to secure an enhanced redundancy package along with relocation payments for those who decided to move to Wrexham.

He praised the "strong" team of union representatives on the shop floor at the Trafford Park site for their efforts over the years.
