Global researchers have linked the rising threat of antimicrobial resistance to rampant environmental pollution.

The scientists noted that discharge of drugs and particular chemicals into the environment was among the most worrying health threats the world over.

They were speaking on Tuesday during the launch of a new report at United Nations Environment headquarters in Nairobi.

UN Environment chief Erik Solheim said there are a number of studies that have linked the misuse of antibiotics in humans and agriculture over the past several decades to increasing resistance, yet the role of the environment and pollution has received little attention.

“This needs priority action right now or else we run the risk of allowing resistance to occur through the back door, with potentially terrifying consequences,” Mr Solheim said during a press briefing.
