What's Happening?
The United Nations Food and Agriculture Organization (FAO) has issued a warning that global antibiotic use in livestock could rise by nearly 30% by 2040 compared to 2019 levels. This increase is projected under a 'business-as-usual' scenario, potentially
exacerbating antimicrobial resistance (AMR), which poses a long-term threat to food security, livestock production, economic welfare, and human health. The FAO's report highlights that Asia and the Pacific are expected to account for nearly 65% of global livestock antimicrobial use by 2040, with South America following at about 19%. The report also introduces the livestock biomass conversion method to improve transparency in measuring antimicrobial use intensity. The FAO emphasizes the need for integrated policies combining regulation with economic incentives to reduce unnecessary antimicrobial use.
Why It's Important?
The projected increase in antibiotic use in livestock is significant because it could worsen antimicrobial resistance, a major global health threat. AMR can lead to ineffective treatments for infections in humans and animals, increasing mortality rates and healthcare costs. The economic impact of AMR is often slow to manifest, which can delay necessary interventions. The FAO's call for treating antimicrobial effectiveness as a global public good underscores the need for international cooperation and investment in sustainable livestock practices. The report suggests that reducing antimicrobial use intensity could mitigate the risks associated with AMR, highlighting the importance of policy alignment and investment in veterinary services and biosecurity measures.
What's Next?
The FAO urges countries to adopt integrated policies that combine regulation with economic incentives and transitional support to reduce antimicrobial use in livestock. This includes investing in veterinary services, surveillance, diagnostics, vaccination, and improved husbandry practices. The report estimates that at least $28.4 billion in transitional investment is needed to cover the short-term costs of action. The FAO's recommendations aim to align national and farm-level incentives with global benefits, promoting sustainable livestock production and preserving antimicrobial effectiveness.
