UPDATE: Paramedics have cleared staff and students from exposure to a deadly pesticide after it was dumped on a Malanda school earlier today.
More than 40 staff and students were in lockdown about midday after pesticide sprayed from a helicopter on a nearby farm drifted over Butchers Creek State School.
Paramedics assessed staff and students for any signs of exposure to what was believed to be organophosphate, but gave them the all clear.
The pesticide is able to attack the nervous system, similar to the way chemical weapon sarin is used.
The students were believed to be in class at the time of the incident.
