"The meat would be shoveled into carts, and the man who did the shoveling would not trouble to lift out a rat even when he saw one—there were things that went into the sausage in comparison with which a poisoned rat was a tidbit. There was no place for the men to wash their hands before they ate their dinner, and so they made a practice of washing them in the water that was to be ladled into the sausage. There were the butt-ends of smoked meat, and the scraps of corned beef, and all the odds and ends of the waste of the plants, that would be dumped into old barrels in the cellar and left there. Under the system of rigid economy which the packers enforced, there were some jobs that it only paid to do once in a long time, and among these was the cleaning out of the waste barrels. Every spring they did it; and in the barrels would be dirt and rust and old nails and stale water—and cartload after cartload of it would be taken up and dumped into the hoppers with fresh meat, and sent out to the public’s breakfast." --Upton Sinclair, The Jungle, 1906.

Explanation:

The author in the novel describes the complex and terrible living conditions of immigrants living in Chicago and how in order to meet their basic needs, they work in the food industries where they are exploited in conditions that violate their rights as workers and that threaten human dignity.

The book aims to show the precariousness and poverty of the working class as well as the deep social inequalities between the rich and the poor. Any way, many people worried more about bad hygiene practices in the meat industry which are described in the text. Sinclair is also interested in showing the corrupt practices and abuse of power of elites who favor their interests at the expense of the lives of workers and consumers health.
