Beyond Pesticides, a Washington, D.C.-based organization opposed to the use of pesticides, has issued a call for comments to the U.S. Department of Agriculture’s National Organic Program (NOP) supporting recommendations by the National Organic Standards Board that would prohibit the use of engineered nanomaterials from certified organic products. According to the organization’s blog, the board passed the recommendations during its October 25-26, 2010, meeting.

Among other matters, the recommendations include a working definition for engineered nanomaterials and propose that engineered nanomaterials be prohibited in both organic production processing and packaging. The board also called for NOP to schedule a symposium on the topic to consider whether the definition is adequate and enforceable and the best regulatory approach to address the matter. Beyond Pesticides is concerned about the unknown “long-term impacts of nanomaterials on human health and the environment.”
