The UK prime minister caused outrage this week when he appeared to trivialise the possibility of having to cull healthy pigs because there isn’t the capacity to butcher them for use in the food chain as intended.

This follows a visit by George Eustice, the UK minister with responsibility for agriculture and food, to the Balmoral Show in Northern Ireland recently, where he was heavily lobbied by farmers and the food industry about the need to address labour issues.
