TIL that “organic cows”in the US can’t be given antibiotics. If they are, they are never “organic”, ever again.

In the EU and Canada, farmers aren’t allowed to sell the milk until there’s no sign of antibiotics.
Personally, I’d prefer if an animal was correctly treated for any ailment they might be suffering from. And antibiotics might be the correct course of action. Feeding antibiotics to healthy animals in their feed is ridiculously irresponsible, however.
How do you microdose veganism? Try eating less meat and dairy products. Go meat free once or twice a week. There are plenty of delicious vegan meals to be made, and you won’t miss the meat.
In the follow-up podcast mentioned, they guide the listener through how someone who wants to reduce animal suffering (but also still eat animals) might think through their dinner menu. They recommended eating good quality beef, which surprised me, but given how prevalent battery hens are, it might be easier to discover if a cow was grass fed.
We’re spoiled in Ireland. Most cows are grass fed, and the EU has laws regarding how densely packed chickens can be. EU MPs voted in favour of banning caged farming by 2027 after intense lobbying by activists.
