According to figures from the NFU, the average price per litre of milk has fallen from 31.66p in June 2014 to 23.66p just a year later. However, the average cost of producing a litre of milk is about 30p, with some farmers being paid as low as 15p per litre. The NFUs East Anglian representative Brian Finnerty said: The price the farmer is being paid is lower than the cost of production. In the longer term, thats just not sustainable. If this continues well see more farms going bust, more herds being sold and more of them going into other types of farming. Third-generation dairy farmer David Herdman said: Theres been a radical shift in the profitability of the business. Weve had three good years, but we will be making a loss in this financial year. Gaynes Farm in Great Staughton near St Neots has been in the family since 1929, but David, who runs the farm with his brother Kevin, said: Wed based our figures on 28p a litre this year, but its down 4p. Theres always been volatility in the market, but not to the extent were now experiencing. At a crisis meeting on Monday (August 10) in London, farming leaders called for urgent talks with the government and for retailers to cut their margins. Waitrose, Marks and Spencer, Tesco, Sainsburys and the Co-op have agreements in place to ensure farmers are paid more than the cost of production. No such agreements are in place with the other supermarkets. After a meeting with farming unions on Tuesday (August 11), however, Morrisons announced it would be introducing a new range of milk, which will have a 10p premium that will be passed directly back to dairy farmers.
