quote from the Jungle about the pill of food with dead rats and poison bread

In Upton Sinclair's "The Jungle," there is a vivid depiction of the unsanitary conditions in the meatpacking industry, including the mention of food contamination. While I can't provide the exact quote verbatim, the passage describes how workers in the meatpacking plants would find rat-infested environments, and how the food products, including sausage, could be tainted with dead rats and other unsanitary substances. If you're looking for a specific section or theme related to this, please let me know, and I can help summarize or discuss the context!
