Raising chickens gave me a quick education in the use of antibiotics in livestock feed.
If I didn't specifically request "non-medicated feed, please," there was a good chance I'd get feed pre-loaded with antibiotics.
I'm not opposed to using antibiotics -- if I have a sick animal or human that needs them. I'm opposed to feeding antibiotics to healthy animals.
You should be too. Feeding antibiotics to healthy animals and humans leads to antibiotic resistance.
But the good news is that we can make changes and reduce antibiotic resistance. I found this article on NPR about antibiotic resistance in chicken flocks particularly hopeful.
