Is there any evidence that antibiotic resistance in any significant way crosses from livestock pathogens to human pathogens? I had a medical professor lecturing a couple years back saying it was basically a myth.
No, there isnt. It’s theoretical.
What’s most concerning isn’t antibiotic use by farms but how wide a range of antibiotics are used. If we limited the industry to only use a specific set of antibiotics that would be one thing, but they keep having access to newer drugs.
