Yeah....too many things wrong with that statement. You do realize that it's fiction with a political agenda, don't you...? This is what President Roosevelt said about Sinclair:
"I have an utter contempt for him. He is hysterical, unbalanced, and untruthful. Three-fourths of the things he said were absolute falsehoods. For some of the remainder there was only a basis of truth.” (Source: letter to William Allen White, July 31, 1906, from “The Letters of Theodore Roosevelt,” 8 vols, Cambridge: Harvard University Press, 1951-54, vol. 5, p. 340.)
I haven't read Sinclair's The Jungle since high school. However I believe he exaggerated food safety procedures as a rhetorical tool in order to incite furor and accentuate overall poor working conditions -- which weren't at all fictional. In that respect, the Triangle Shirtwaist factory fire (occurring 5 years after the Jungle was published) was also a large turning point in worker rights and safety....

I personally try to eat the whole animal, including bone and organ meat. Asians eat this way and are extremely healthy. So that aspect of hot dogs and sausages containing whole animal parts doesn't bother me, especially if they employ natural animal casing.
However I avoid any foods with food preservatives such as nitrites and nitrates and instead opt for fresh foods.
