The World Health Organisation says pesticide poisoning is the probable cause of mysterious deaths of over 18 people in Ode Irele, in Irele Local Government Area of Ondo State.
Those who died suffered from blurred vision and headaches, and then lost consciousness before dying within 24 hours.
The “current hypothesis is cause of the event is herbicides,” WHO spokesman Gregory Hartl, said in a tweet.
“Tests done so far are negative for viral and bacterial infection,” he added.
The WHO spokesman said the current theory was that the deaths were caused by weedkiller.
