UK food maker Samworth Brothers has confirmed that the palm oil used in all its Ginsters pasties, slices and sausage rolls will now come from certified sustainable sources.

Samworth said it was the first UK manufacturer within its category to use palm oil certified by the Roundtable on Sustainable Palm Oil (RSPO).

The change, which was announced on Friday (9 September), will mean that over 100m Ginsters products a year will now contain sustainable palm oil.

The chilled foods firm said Ginsters had previously been buying Green Palm certificates for the palm oil used within its margarine. It said the use of the certificates represented "the best approach" while there was a "very limited supply" of 100% sustainable palm oil available.

The move to sustainable palm oil will not mean an increase in the price of its products, Samworth added.
