Researchers identified "antibiotic resistance genes" in waterways and soils near factory farms in the U.S., according to a report shared exclusively with Newsweek.
At least 700,000 people die each year from drug-resistant infections.
According to the World Heath Organization, antibiotic resistance is an "increasingly serious threat to global public health that requires action across all government sectors and society."
The bacteria, known as Pseudomonas aeruginosa, is found widely in the environment although infections usually occur in hospitals among people with weakened immune systems.
Medical researchers have known for decades that the pipeline for new drugs to stave off bacterial infections would one day run dry. That day is now at hand.
Antibiotics have saved countless lives over the years, but as deadly bacteria grow immune, those miracle drugs stop working.
Drug-resistant superbugs kill 700,000 people every year around the world.
The drug was discovered in the late 1970s.
All 193 U.N. member states are set to sign a declaration to combat drug-resistant superbugs.
Scientists have developed a new alternative to antibiotics that could revolutionise the way we treat superbugs and avoid a scenario in which people die from routine procedures
