I also worked as a canvasser in 2019 and 2020 for the US census and, while we were about as thorough as you could reasonably get, the whole operation made me somewhat skeptical of official statistics in general. 2020 in particular was a bit of a disaster due to the pandemic and when the statistics were published, a bunch of mainstream news outlets published stories about certain areas experiencing "population decline" and all I could think was that those were actually the areas where the census didn't manage to count everyone.

I think of these things because I worked in a kitchen that made dough, and our dough mixer always needed to be lubricated. I once found grease that had dripped from above into the mixing bowl. Luckily I am someone who takes such things seriously, but there are a lot of careless people out there. Even if you wipe off grease, an invisible trace amount will remain on the surface unless you clean it with a solvent. I also worked in a warehouse that stored machine parts used in food packaging equipment. There was drywall work being done at the time and the whole place was coated in gypsum dust. I remember handling "food grade" lubricant and looking up its safety data sheet (SDS) out of curiosity, and my takeaway from reading it was that it's still probably not something you would want to eat.
