Why is antibiotic stewardship important in farming and medicine?

• A. It increases antibiotic use to prevent disease spread.
• B. It has no impact on resistance.
• C. It only matters in hospital settings.
• D. It reduces selection pressure for resistance, slows resistance spread, and preserves antibiotic effectiveness.

Answer: (D)

Antibiotic stewardship aims to minimize unnecessary antibiotic exposure to keep these drugs effective. In farming and medicine, that means using antibiotics only when there is a real need, choosing the right drug and dose, and finishing the course, while also improving prevention through vaccination, hygiene, and biosecurity to reduce infections. When usage is kept appropriate, the selection pressure that drives resistance is lowered, which slows the spread of resistant bacteria across people, animals, and the environment and helps preserve antibiotic effectiveness for future treatments. Increasing use would push resistance faster, and resistance is influenced by antibiotic practices everywhere, not just in hospitals, so stewardship is relevant in farming as well.
