Prion diseases. Accumulation of different substances, like mercury, lead, strontium-90, and, a new contender to the list: micro plastics. And you'll want to have a look at a person's medication and likely want to make sure they've been off of it for a few days before consuming their flesh.
Farm animals are legally allowed to eat actual plastic, not only microplastics. If you’re afraid of microplastics or accumulation of substances maybe don’t eat meat.
Legal limit of plastic in animal feed is 0.15% in the EU
A cow eats 25kg of dry food a day
25/100*0.15 = 0.0375kg = 37.5grams
A plastic bag weighs 6-8grams.
You are legally allowed to feed your cow 5 plastic bags a day (as a snack)
Bioaccumulation concentrates more pollutants the higher up the food chain you go. It is part of why most meat we eat comes from vegetarian animals. The fish we eat are often predatory so common advice is the keep the smaller and younger ones that are still big enough to be worth filleting. You don't actually want to eat a trophy sized fish because they've accumulated more pollutants. Trophy sized fish are better off being realsed, they are often good breeders and help keep healthy population numbers.
Of course, something that eats cows that eat a shitton of plastic, will have even more plastic in it.
But that doesn't mean that it's healthy to eat an animal that has been fed (assuming they are slaughtered at 3 years, and ignoring the climate impact, the ethics of slaughtering an animal in its youth, etc)..
Thanks for your feedback, I was guesstimating off the top of my head. On doing some research, I see meat cows are usually slaughtered at 18 months - 2 years old in the Netherlands.
OK, mate, I have good news and bad news. The good news: we're having a feast and you're the guest of honour. The bad news: you need to stop taking your meds for a few days.
The problem is bioaccumulation: taking in substances faster than you can metabolize and excrete them. Eating something that has already accumulated something is worse than accumulating it from the same original sources. That's why you can do suicide by vitamin A poisoning by eating carnivore livers.
It's also the case that when you're eating plant-based foods, unlike meat and dairy products, you're eating alpha- and beta-carotene and beta-cryptoxanthin, which your body can convert to Vitamin A and which don't cause hypervitaminosis.
So if you're just learning "Oh, shit, Vitamin A can poison me", don't let that hold you back from squash, yams, carrots etc.
aren't prion diseases usually just a thing for the brain? though I haven't considered the medication aspect... I want to eat a human heart some day, any other things I'd need to consider? I guess I'll just take the risk with the medications.
the funny thing is I'm being entirely serious. I need a heart transplant and if I survive I want to turn my old heart into burgers and share them with my girlfriend and boyfriend.
the doctor said I can get it back. though it'd be in formaldehyde and after they did sciencey stuff on it, not sure if its still edible at that point. if eating it isn't an option I'll make pendants out of it. cut a part off and put it in a little glass vial.
Is there enough substance to turn it into burgers, plural? An average human heart is, what, fist-sized I think? Seems to me like you'd get one, maybe one and a half patties out of that, no? And you probably can't even use all of it, I'd assume.
