The cost of a litre of milk in Jersey has increased by 5%. Jersey Dairy said rising "packaging, utility, and freight costs" meant it was having to charge suppliers more.
That charge could then be passed on to shoppers as well, said the firm.
It means the average litre of milk is now 7p more expensive.
It follows an increase by 15p a litre in the average wholesale price of milk in 2023.
In 2022, Jersey Dairy put up the price of milk by 8p a litre.
The price of a litre of milk on the island in shops in 2022 was between £1.24 and £1.29.
