APHIS regulates the importation, interstate movement, or environmental release (i.e., outdoor field trials) of certain organisms developed using genetic engineering (including plants, insects, and microbes) that may pose a plant pest risk. Permit applications, which are carefully reviewed by APHIS regulatory scientists, provide details about the nature of the organism and the conditions that will be used to prevent the spread and establishment of the organism in the environment. A permit may include additional conditions to help prevent unauthorized release into the environment.
