Pesticide residues tested in 1997 were generally low and thought to pose no detectable threat to health.[2] More recent research shows a link between pesticides and Parkinson's disease,[3] and on the foetus.[4]
The Soil & Health Association of New Zealand and the Pesticide Action Network Aotearoa New Zealand claim that the 2010 results are the worst ever. Some of the results include:[5]
Pesticide residues found in 94% of targeted fruit and vegetable samples
Prohibited endosulfan in 11 of 23 cucumber samples
Dangerous fungicide exceeding allowable levels in 9 out of 24 Pak choi samples
18 different pesticides found among 24 grape samples
