Summary

Story summary

Researchers from countries published study on 26 May 2026 linking a 10% rise in salmonella antibiotic-resistance genes to climate change.
They examined 480,000 genomes from 139 countries (1940-2023) and found a 38% increase in antibiotic-resistance genes.
Climate factors contributed 10% of the rise in salmonella antibiotic-resistance genes.
Surges were strongest in the Middle East and North Africa, followed by South Asia and sub-Saharan Africa.
