Food Standards Australia New Zealand: In 2015 an expert toxicologist prepared two reports for FSANZ on the potential use of nanotechnologies in existing food additives and food packaging. The reports were then peer reviewed by an expert pharmacologist and toxicologist to evaluate whether the conclusions for each of the reports were supported by the weight of evidence in scientific literature. The peer review agreed with the overall conclusions of the reports.

The consultant was asked to review publically available scientific literature on whether there is reasonable evidence of health risks associated with oral ingestion of titanium dioxide, silicon dioxide and silver in food. These food additives may contain a proportion of material with at least one dimension in the nanoscale range. As an extension of this work, evidence of risks to health from nanomaterials used in food packaging was also investigated.
