Heinz have blamed an "inefficient" supply chain to its markets in the Far East for the loss of 45 jobs at its factory in Kendal.
The company said that it was not cost efficient to produce baby milk products in Cumbria for export to Asia.
Instead, it says the factory in Mint Bridge Road will be making infant milks products for the European market and infant cereals and nutrition products for the UK.
It will use facilities in New Zealand to produce milk for the Far East.
“With an expanding distribution, supplying infant milks from the UK to Heinz markets in Asia and the Far East is increasingly uncompetitive and is not efficient or sustainable in the long-term.
“As a result, it is proposed that the Kendal site will focus production on infant milks for continental Europe together with dry infant cereals and nutrition products for the UK market.
“Under the proposals, including a broader efficiency review at the site, there would be a loss of 45 roles across production and management functions.”
