A formative part of my reading was Upton Sinclair's The Jungle. While its theme was the de-humanisation of people that concerned him , the exposure of the conditions of the meat industry was what brought the book to prominence. This article reveals that those horrific sickening brutalising conditions have little changed.
"Garcia ... had been stuck with one of the worst spots on the line: running a device known simply as the "brain machine"—the last stop on a conveyor line snaking down the middle of a J-shaped bench [DC] called the "head table." Every hour, more than 1,300 severed pork heads go sliding along the belt. Workers slice off the ears, clip the snouts, chisel the cheek meat. They scoop out the eyes, carve out the tongue, and scrape the palate meat from the roofs of mouths. Because, famously, all parts of a pig are edible ("everything but the squeal," wisdom goes), nothing is wasted. A woman next to Garcia would carve meat off the back of each head before letting the denuded skull slide down the conveyor and through an opening in a plexiglass shield. On the other side, Garcia inserted the metal nozzle of a 90-pounds-per-square-inch compressed-air hose and blasted the pigs' brains into a pink slurry. One head every three seconds. A high-pressure burst, a fine rosy mist, and the slosh of brains slipping through a drain hole into a catch bucket. (Some workers say the goo looked like Pepto-Bismol; others describe it as more like a lumpy strawberry milkshake.) When the 10-pound barrel was filled, another worker would come to take the brains for shipping to Asia, where they are used as a thickener in stir-fry. Most days that fall, production was so fast that the air never cleared between blasts, and the mist would slick workers at the head table in a grisly mix of brains and blood and grease...For eight hours, Garcia stood, slipping heads onto the brain machine's nozzle, pouring the glop into the drain, then dropping the empty skulls down a chute."
