According to an analysis, nature publication claims that the use of antibiotics in animal farming is a major contributor to antimicrobial resistance. It is expected to grow by 8% between 2020 and 2030 despite ongoing efforts to curtail its use. Many governments have struggled to make or enforce rules to decrease antibiotic usage. Calculating the amount of antibiotic use is problematic because countries do not publicly publish their antibiotic usage data, says the study's co-author, Thomas Van Boeckel, a spatial epidemiologist at the Swiss Federal Institute of Technology (ETH Zurich). China currently uses more antibiotics in farming than any other country. Pakistan is expected to see the highest growth.
The authors estimate that by 2030, the world will use around 107,500 tons of antibiotics in livestock per year, compared with just under 100,000 tons in 2020. Antibiotic use is highest in Asia, and China in particular, a trend that is expected to continue until 2030. The researchers also estimate that antibiotic use will grow the fastest in Africa, rising by 25% between 2020 and 2030 owing to increased demand for meat products. @ https://www.nature.com/articles/d41586-023-00284-x
