Canterbury study links common herbicides to antibiotic resistance

Bacteria such as salmonella and E. coli can develop antibiotic resistance at rapid rates when exposed to commonly used agricultural herbicides, a University of Canterbury study has found.

A team of five researchers tested the impact of two commercial weedkillers, Kamba (dicamba) and Roundup (glyphosate), on bacteria in laboratory trials. They found that bacteria could acquire antibiotic resistance at up to 100,000 times faster than previously demonstrated.

The results are published online in the open-access journal PeerJ.
