Hundreds of jobs at risk at Dairy Crest Nearly 500 jobs are under threat after supermarket milk supplier Dairy Crest announced plans to close two factories. The proposed closures involve a glass bottling dairy at Aintree, where 220 people work, and a site at Fenstanton in Cambridgeshire which employs 250 people. Chief executive Mark Allen said the dairy closures would protect the future of the dairies side of the business. He added: "The decision to consult on the closure of our Aintree and Fenstanton facilities has not been taken lightly, but we believe that this proposed restructuring of our dairies business is the right decision for the long term." A recent £75 million investment programme has enabled the company to transfer work to its three polybottle dairies at Severnside, Chadwell Heath and Foston in Derbyshire. Dairy Crest, which employs 4,000 people in its dairies business and 6,000 people overall, also announced that its current contract to supply liquid milk to Tesco will not be renewed in July. The demise of the Aintree site reflects the fall in sales of milk in glass bottles as residential trade continues to decline and customers increasingly opt for plastic bottles and milk bags.
