Since the first regulatory approval of a genetically engineered (GE) plant was issued in
1992, hundreds of additional GE plants, thousands of regulatory decisions and millions of
tons of GE grain and seed have been produced. In an increasingly global economy, the grain
and seeds move relatively freely across national jurisdictions, but the regulatory
decisions and associated data and analyses do not. Combined with the realities of
agricultural production, this has led to a legal and regulatory challenge due to the low
level presence (LLP) of GE grain or seeds that do not have regulatory approvals in the
country of destination. In order to assist regulators in conducting environmental risk
assessments related to LLP, reviews of environmental safety data, including associated
regulatory analyses and decisions, for proteins commonly introduced in GE plants have been
produced.
