Going back to farming, the Federal government assumed near total control over a great of it in the New Deal, down to how much you could charge for selling a kosher chicken (A.L.A. Schechter Poultry Corp. v. United States "the surname Schechter means "slaughter" in Yiddish, and specifically refers to a ritual slaughterer") and the two have been inextricably linked since then.
And until about now things have been a lot better, for before WWII at the same time food production was limited by diktat and there were newsreels of it being destroyed, the USDA also believed about a quarter of the nation was malnourished which was confirmed in the WWII draft. Which I've read was major factor in establishing the school lunch program.
