Unless you grow and/or slaughter ALL your own food, you have eaten and will continue to eat both the intentional and unintentional shit, piss, spit, and cum of food processors, transporters, and preparers your entire life.
I know that freaks a lot of people out, personally it just reminds me that the idea of being clean in this world has always been a illusion and that there’s no point obsessing over something out of my control.
If we wanted that to happen significantly less, we could compensate and respect said workers commensurate with their vital role to society, fulfilling a universal basic human need, instead of treating them like shit, paying them shit, and calling food preparation/processing/serving “unskilled,” but we won’t, so enjoy!
