Episode notes
Antibiotic Resistance Threat
- Overuse of antibiotics is causing bacterial resistance, posing a significant threat.
- The UN predicts antimicrobial resistance will be the leading cause of death by 2050.
History of Antibiotic Use in Animals
- Widespread antibiotic use began in the 1950s to treat sick animals and boost growth in livestock.
- The practice led to increased animal protein consumption but also fueled antibiotic resistance.
How Resistance Develops
- Giving small, regular antibiotic doses to animals, like not finishing a prescription, allows resistant bacteria to develop.
- This practice creates a reservoir of antibiotic-resistant bacteria across entire industries.
