In the August 15, 2017, Federal Register, FDA issued a final rule amending the regulations for food additives to provide for the safe use of oil from a variety of bioengineered safflower in complete dry adult maintenance dog food. The safflower variety has been bioengineered to contain a gene from the water mold Saprolegnia diclina responsible for production of gamma-linolenic acid ("GLA") in the seed oil. This GLA-enriched safflower oil will be used as a source of omega-6 fatty acids in dry food for adult dogs. This action is in response to a food additive petition filed by Arcadia Biosciences, Inc., which in the September 14, 2017, Federal Register, petitioned the FDA also to amend the food additive regulations to provide for the safe use of GLA safflower oil as a source of omega-6 fatty acids in dry food for adult cats in the maintenance life stage.
