Hello, did you know Upton Sinclair made a book named "The Jungle" it included all the problems about food safety. This book made the meat inspection happen in 1906.
"Almost as an afterthought, Sinclair included a chapter on how diseased, rotten, and contaminated meat products were processed, doctored by chemicals, and mislabeled for sale to the public. He wrote that workers would process dead, injured, and diseased animals after regular hours when no meat inspectors were around. He explained how pork fat and beef scraps were canned and labeled as "potted chicken."
"Sinclair wrote that meat for canning and sausage was piled on the floor before workers carried it off in carts holding sawdust, human spit and urine, rat dung, rat poison, and even dead rats. His most famous description of a meat-packing horror concerned men who fell into steaming lard vats."
