Abstract:
The safety assessment of nanomaterials in food is essential for safeguarding supervision and maintaining public health. However, there are still no safety assessment procedures for nanomaterials established in national-level in China and no specific toxicology and safety assessment procedures about nanomaterials for food, too. These factors lead to restriction on food safety protection and supervision. Current methods of evaluating the safety of nanomaterials mainly rely on traditional toxicological assessment that are extrapolated based on animal experiment from high doses to low doses and from animals to humans. These uncertainties restrict the accuracy of safety assessment for nanomaterials and also limit the development of scientific and effective evaluation procedures and regulatory measures. Currently, the key issues need to be solved including exposure assessment and evaluation methods of nanomaterials in food and the established methods of the toxicity test for nanomaterials that are consistent with the objectives of toxicity test in the 21st century vision and strategy. In this article, we reviewed current administrative regulatory, situations, and existing issues of food nanomaterials either in China or some developed countries in order to provide a scientific basis in establishing safety assessment procedures for nanomaterials in food in the future.
