Antimicrobial resistance (AMR) is recognised by the World Health Organization (WHO) as one of today's greatest global health challenges. The organisation has warned that we may be entering an era in which antibiotics are no longer effective to cure simple, and previously treatable, bacterial infections. This would mean that currently treatable infections such as pneumonia, tuberculosis, and blood poisoning could become fatal. It would also mean that it would no longer be possible to use antibiotics to prevent infection in routine medical procedures, such as joint replacements and chemotherapy.

Last year, a WHO report acknowledged the role of the environment in spreading resistance. Now, this new research, published in the journal mBio indicates the environment should be considered on an equal footing with antibiotic exposure in humans and animals, where prevention efforts have been most concentrated so far.
