The price of Lurpak butter is nearing £10 in some supermarkets, with Arla Foods, the parent company of Lurpak and Cravendale, saying inflation is also hitting its farmers.
Customers at Iceland noticed that a kilogram of Lurpak butter was priced at £9.35, while Sainsbury’s listed a 750g tub for £7.25.
Arla Foods said in a statement, quoted by BBC News, that it understands "inflation in food price is hitting many households really hard right now".
"Unfortunately, our farmers are facing a similar situation with prices for feed, fertiliser and fuel they need to produce milk."
"While we don't set the prices on the shelves, we do work closely with the retailers to ensure our farmers receive a fair price for the milk they produce."
The UK is currently facing the worst inflation in 40 years at 9.1% for the 12 months to May.
