Pollution
At Truro Crown Court in December 2021, Dairy Crest admitted charges relating to a series of incidents of serious pollution between December 2015 and January 2021, including the illegal discharge of "biological sludge" and "suspended solids" from its creamery at Davidstow into the River Inny, Cornwall.[23] Fines of £1.52 million and costs of £272,747 were imposed on the company in June 2022.[24] It was reported that there was a possibility that the royal warrant could be removed as a result of the pollution.[25]
In 2025 the company said it was making the switch from producing demineralised whey and galacto-oligosaccharides, which it began producing in 2013 in order to return to the production of sweet whey powder.[26]
The Environment Agency cited the Davidstow site as a persistently poorly performing site in the 2024-25 Chief Regulator’s report.[27] The Environment Agency has initiated a consultation process for a new permit aimed at the Davidstow creamery. This new permit aims to introduce environmental improvements and allow an increase in cheese production.[28]
More broadly, as the operations are dependant on intensive dairy farming, there is a strong link with the decline in the health of local river systems. The EA has also confirmed that the dairy industry is the largest single cause of agricultural pollution, accounting for the majority of all serious pollution incidents caused by agriculture. The majority of such pollution incidents relate to the mishandling of dairy slurry and silage.[29]
The company has also polluted other rivers in the UK. Pollution in 2023 and 2025 in a tributary of the River Ure was caused by a faulty drainage system at its Wensleydale Creamery in Hawes.[30]
Saputo's other international subsidiaries have also been prosecuted for pollution. An accident at a facility in Tulare, California on June 22, 2018, led to the release of 5,690 pounds of anhydrous ammonia. Owned by Saputo Cheese USA Inc. the facility produced mozzarella cheese and whey protein concentrate.[31] In total, Saputo subsidiaries in the USA have been fined on at least nine separate occasions by government agencies for environmental breaches since 2001.[32]
