When did antibiotics start being used in animals?

As a result, livestock in these environments commonly require aggressive infection management strategies, which often include the use of antibiotic therapy. Antibiotics are used in food animals to treat clinical disease, to prevent and control common disease events, and to enhance animal growth.

Does eating animals treated with antibiotics affect human resistance?

Bottom Line: There is no clear-cut link between antibiotic use in animals and resistant bacteria infections in humans. The risk to human health is likely to be small, since adequate cooking destroys bacteria in food.

Does eating meat cause antibiotic resistance?

“[C]urrent evidence indicates that there is no direct impact of antibiotic residues in meat on human health, but the risk of generating antibiotic-resistant bacteria in animals poses a potential risk to humans. However, human antibiotic use is far more damaging in both respects.”
