The FDA is still considering approving GE salmon. It has also said it will probably not be labeled.
Kroger, the US's leading grocery chain with 2,424 stores, informed Friends of the Earth of its decision in an email from Keith Dailey, director of media relations at Kroger.
"Should genetically engineered salmon be approved, Kroger has no intention of sourcing it", Dailey wrote.
Safeway, the number two conventional grocer with 1,406 stores, confirmed their position in an email to Friends of the Earth last week and said they plan to post their statement online:
"Should GE salmon come to market, we are not considering nor do we have any plans to carry GE salmon. The seafood products we offer will continue to be selected consistent with our Responsible Seafood Purchasing Policy, Responsible Sourcing Commitment and our partnership with FishWise."
Campaigners welcome the move
Dana Perls, Food and technology policy campaigner with Friends of the Earth, said: "By making commitments to not sell genetically engineered salmon, Kroger and Safeway have joined the large number of grocery chains, from Trader Joe's to Target, that have wisely chosen to listen to the majority of consumers who do not want to eat genetically engineered fish"
"Now Costco, Walmart, Albertsons and other retailers need to catch up and provide their customers with what they want: natural, sustainable seafood that isn't genetically engineered in a lab."
Andrew Kimbrell, executive director of Center for Food Safety, said: "Genetically engineered salmon are bad for the consumer, bad for the environment, and bad for our native salmon. We call on all fish retailers to reject this dangerous product that consumers don't want."
The total number of companies committed to not sell genetically engineered salmon now stands at more than 60 retailers, including Target, Whole Foods, Trader Joe's, Aldi, H-E-B, Meijer, Hy-Vee, Marsh, Giant Eagle, and now Safeway and Kroger, representing more than 9,000 grocery stores across the country.
FDA: GMO fish, animals may not be labeled
Nearly 2 million people have written to the FDA opposing the approval of genetically the engineered salmon, in response to Aqua Bounty's revised draft environmental assessment in 2013. Despite this outcry, the FDA is still considering approving GE salmon.
It has also said it will probably not be labeled, so consumers will have no way of knowing if the fish they are feeding their families is genetically engineered.
At least 35 other species of genetically engineered fish are under development, and the FDA's decision on this genetically engineered salmon application will set a precedent for other genetically engineered fish and animals - including cows, chickens and pigs - to enter the food markets.
Americans in revolt
Three quarters of Americans surveyed in a New York Times poll said they would not eat genetically engineered fish, and 93 percent wanted GMO foods to be labeled. Polls show that 80 percent of Americans who regularly eat fish say sustainable practices are "important" or "very important" to them.
The supermarket rejection of genetically engineered salmon is part of a growing trend of food companies distancing themselves from GMO foods. Chipotle (NYSE: CMG) is removing and labeling GMOs and Whole Foods (NASDAQ: WFM) will require GMO foods in its stores to be labeled by 2018.
Cereal giant General Mills (NYSE: GIS) recently removed GMO ingredients from Cheerios and Post (NYSE: POST) quickly followed suit, removing GMOs from Grape Nuts. McDonald's (NYSE: MCD) and Gerber (OTN: NSRGY) have said they have no plans to buy the GMO apple that is pending approval by USDA.
