I’m old enough to remember that penicillin cured almost everything. You started a 10-day course, and felt better in a day and a half.

The problem was that many folks stopped taking it, when they felt better.

These days, American meat is absolutely overflowing with antibiotics. I don’t know if there’s any kind of serious effort to address that.
