What's a good argument against the use of antibiotics in animal feed?
assistant
I think that there are some valid arguments for and against the use of antibiotics in animal feed, but it’s hard to say which side is more persuasive. For example, one argument against using antibiotics in animal feed is that it can lead to antibiotic resistance among bacteria that cause disease in humans. On the other hand, if you don’t use antibiotics in animal feed, then animals may get sick from diseases caused by bacteria that aren’t affected by the antibiotics. So, it depends on what you value more—preventing human illness or preventing animal suffering.
