One of Glanbia’s more interesting milk contracts came to my attention this week.

Glanbia Consumer Foods Ireland supplies milk, yoghurt, butter and other dairy products to Mountjoy Prison, Arbour Hill Prison and Shelton Abbey Open Prison. The dairy contract is worth almost €1.73m to Glanbia and three other companies, Brakes Ireland, BWG Foods and Pallas Foods.

The four also have contracts with prisons in Limerick, Cork, Portlaoise and the Defence Forces camps in the Curragh, Haulbowline and elsewhere, amounting to a further €2.3m.

I’m reliably informed that the prisons have upgraded their order from ordinary pasteurised milk to vitamin D-enriched milk.

Apparently the inmates may not be getting their daily requirement of vitamin D from sunlight due to their incarceration.
