An analysis has found that climate change is associated with a 10 per cent increase in antibiotic resistance genes in salmonella bacteria.

Findings published in The Lancet Planetary Health journal show that 82 per cent of the countries studied saw increases in antibiotic resistance genes in salmonella, an enteric bacteria that can cause food poisoning and typhoid fever, with the strongest climate-associated increases occurring in the Middle East and North Africa, followed by South Asia, and Sub-Saharan Africa.
