The Brain Machine and the Sick Workers
At Quality Pork Processors, the contractor that slaughtered hogs for Hormel's Austin, Minnesota plant, workers at the 'head table' used a compressed-air nozzle to blast pig brains out of skulls as a fast way to harvest them for sale. Around 2007, Minnesota health investigators linked a cluster of workers suffering numbness, weakness, and fatigue to that station. Inhaling aerosolized brain tissue had triggered an autoimmune attack on their own nerves, a newly identified disease called progressive inflammatory neuropathy.
