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.

The cow can have a little bit of plastic. As a treat :)
