The U.S. Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) has determined that Phalaenopsis orchid (ISK-311NR-4), developed by Ishihara Sangyo Kaisha, Limited, using genetic engineering to have modified flower color. According to APHIS, it is unlikely that the bioengineered blue-purple moth orchid will pose a greater risk as a plant pest than the unmodified comparator. Thus, the orchid is no longer subject to their regulation for products of genetic engineering.

APHIS listed the basis of their decision, including information and data submitted by the developers as requirements for the petition to deregulate, existing scientific data, and public comments on the Federal Register notice regarding the petition and plant pest risk assessment.
