The UN predicts that antimicrobial resistance will be our biggest killer by 2050. "That should really scare the hell out of all of us," says bioprocess engineer Leon Marchal. He's working on an urgently needed solution: transforming the massive, global animal feed industry. Learn why the overuse of antibiotics in animal products, from livestock feed to everyday pet treats, has skyrocketed worldwide -- and how we can take common-sense measures to stave off a potential epidemic.

Leon Marchal: The urgent case for antibiotic-free animals

The urgent case for antibiotic-free animals

By 2050, antimicrobial resistance could surpass cancer as our top killer, a dire forecast urging immediate action in antibiotic use.

50-80% of global antibiotics feed livestock, not humans, fueling a rise in resistant bacteria that threatens both animal and human health.

Transitioning to antibiotic-free animal feed through improved hygiene, nutrition, and microbiome management offers a beacon of hope.
