After a dairy products tainting scare earlier this year, a Government report shows traces of soil- treatment product DCD were found in 371 samples, affecting mainly milk powder.
Traces were also found in one butter and 11 cheese products.
The Government does not know where the DCD-tainted products went, although some would have been sold in New Zealand.
However, the levels of DCD, or dicyandiamide, are "safe" and mostly less than 1 part per million, the report says.
DCD is "nitrogen inhibitor" used on pastures to reduce the harmful environmental effects of urea use and runoff from cow effluent.
Fonterra tests discovered the tainting in September, but the public and export markets were not told until later January, four months later. The Ministry for Primary Industries admitted yesterday it did not know where the products went and there would still be products in the supply chain with DCD traces.
Director-general Wayne McNee said the levels were not a food safety concern.
