The United Nations (UN) Food and Agriculture Organization (FAO) and World Health Organization (WHO) have released a draft paper entitled State of the art on the initiatives and activities relevant to risk assessment and risk management of nanotechnologies in the food and agriculture sectors for comment. FAO and WHO commissioned the paper with the objective of summarizing and analyzing the information that has become available since their 2009 expert meeting and determining possible courses of action. The draft paper reviews national and international activities on the risk analysis of nanomaterials in the food and agriculture sectors that have been carried out since the meeting. It presents national and international risk assessment and risk management approaches that identify and implement strategies to address potential hazards associated with the use of nanotechnology-related products or techniques. Information on relevant regulations and risk assessment activities was gathered from the websites of 16 national and international institutions, organizations, and governments. Information on actual and planned uses of nanomaterials resulting in human exposure through food or food packaging/contact materials since 2009 was collected from a variety of sources, including the scientific literature, websites, patent databases, market analysis reports, and material presented at conferences, workshops, and symposia. Comments are due November 30, 2012.
