Recent information from Animal Control Products Ltd is that DoC buy between 30% and 50% of their 1080 product every year, that OSPRI and regional councils account for another 40%, and (presumably) ZIP and Predator Free NZ account for the rest…. between 10% and 30%.
As DoC have produced maps showing they intend to be covering 1.124 million ha with aerial 1080 this year, at a rate of 1.5 to 2 kgs per ha, and even if they account for a 50% buy-up of the poison, we can safely assume a total of about 4,000 tonnes of 1080 poison baits will be spread on our land this year.
That is 6,000kgs of pure 1080 poison (at the standard 0.15% pure poison per bait rate).. So at an LD50 of 0.5mg per kg bodyweight that means 35mg can kill a 70kg human being. That works out to be theoretically enough 1080 dropped on NZ this year to poison 171,428,571 x 70kg people, with half of them, 85,714,285, having a lethal dose!
LD50 : [ Based on fatal or near-fatal cases of human poisonings, the dangerous dose for humans is 0.5-2.0 mg/kg BW (Negherbon 1959)]
(LD50 stands for Lethal Dose 50 – killing with poison is not an exact science so an LD50 is used, which means that one can assume 50% of the people poisoned will die. It doesn’t mean the other 50% get off scot-free!)

If you are new to NZ’s 1080 poisoning program here is a good article to start with …
A must watch also is Poisoning Paradise, the doco made by the GrafBoys (banned from screening on NZ TV, yet a 4x international award winner). Their website is tv-wild.com. Their doco is a very comprehensive overview with the independent science to illustrate the question marks that remain over the use of this poison. Check out also 1080science.co.nz for the independent science.
And the 1080 pages at the main menu, particularly the sub tab, ‘suspected 1080 poisoning cases’. Finally, remember what the retired MD Charlie Baycroft said recently …‘if you die from 1080 poisoning, nobody will know because the Ministry of Health is bullying NZ Doctors into not testing for 1080′.
