Whether they eat meat or not, most people in the UK have never been inside an abattoir - and for good reason. They are filthy, dirty places. There's animal faeces on the floor, you see and smell the guts, and the walls are covered in blood.
And the smell... It hits you like a wall when you first enter, and then hangs thick in the air around you. The odour of dying animals surrounds you like a vapour...
As I spent day after day in that large, windowless box, my chest felt increasingly heavy and a grey fog descended over me. At night, my mind would taunt me with nightmares, replaying some of the horrors I'd witnessed throughout the day...
Whenever I walked past that skip, I couldn't help but feel like I had hundreds of pairs of eyes watching me. Some of them were accusing, knowing that I'd participated in their deaths. Others seemed to be pleading, as if there were some way I could go back in time and save them. It was disgusting, terrifying and heart-breaking, all at the same time. It made me feel guilty. The first time I saw those heads, it took all of my strength not to vomit.
