(CNN)Genes detected in antibiotic-resistant superbugs in the High Arctic originated in India, a new study finds.
A total of 131 genes associated with resistance to antibiotics were discovered by a team of scientists, with one of the genes first found in New Delhi in 2008.
The genes were discovered in soil samples from the Kongsfjorden region, a remote place in the High Arctic, according to the study published Monday in the journal Environment International.
"The only way these genes could have got there is either though traveling wildlife or through traveling humans," lead researcher David Graham, professor of Ecosystems Engineering at Newcastle University in the United Kingdom, told CNN.
There has been increasing urgency to tackle antibiotic resistance as drug-resistant bacteria are expected to kill 10 million people a year by 2050.
Scientists estimate that around 70% of bacteria that cause infections are already resistant to at least one antibiotic used to treat them, largely fueled by their overuse.
Last week, UK Health Secretary Matt Hancock said drug-resistant superbugs are as big a threat to the world as climate change or wars, and he unveiled a five-year action plan for the UK.
Graham and his international team agree with global strategies to combat antibiotic resistance that target minimizing the
