AquAdvantage–a patented Atlantic salmon that includes genetic material from two other fish species–has been the subject of controversy for years, but on Nov. 19, the U.S. Food and Drug Administration said its scientists had deemed it safe for humans to eat. It’s the first genetically modified animal the agency has greenlighted for human consumption. The fish will be bred in land-based tanks in Canada and Panama. Gene-altered salmon may have trouble winning over some consumers and retailers who are wary of the potential environmental and health hazards of eating genetically modified animals. Here’s what all the fuss is about. Is genetically modified salmon safe to eat? The FDA says its scientists “rigorously evaluated extensive data submitted by the manufacturer, AquaBounty Technologies, and other peer-reviewed data” and determined that the salmon is safe to eat for both humans and animals. There was no difference, from a safety perspective, between eating farmed salmon and eating AquAdvantage salmon. Most of the studies in which animals ate genetically modified foods do not show any serious health effects. A small number of studies do hint at possible problems–but research on the long-term safety for humans is scant. Will I know which salmon are genetically modified and which are not? Not necessarily. There is no regulation in the U.S. requiring companies to label genetically modified organisms (GMOs) as such. That means any indication to consumers that a food is genetically altered would be voluntary. But the FDA did issue recommendations for how companies should note genetic changes should they choose to do so. What other GMO foods are approved? Most corn, soy, cotton and sugar beets–as well as some alfalfa, potatoes, papaya and other crops–that are grown in the U.S. are genetically engineered to either produce higher yields or resist pests and drought. Up to 80% of the processed foods sold in the U.S. contain GMOs. What does gene-altered salmon taste like? AquaBounty says it is indistinguishable from farm-raised salmon. Why do some people oppose GMOs? Opponents have several concerns. First, the genetic alterations could change the plant or animal in ways that could be harmful for the people who eat it. Some worry that tinkering with genes may cause changes that could damage the plant or animal by making it less fit for survival. Finally, AquAdvantage salmon are raised in containers, not in the wild, but if the new species were to make its way into rivers and oceans, for instance, some worry that it could alter the existing environment. Will changing the genes harm the fish? The data isn’t clear on this yet. Studies have shown that genetically altered fish tend to eat more to support their growth-promoting genes, but AquaBounty says its salmon consume 25% less feed than Atlantic salmon. Where will the genetically modified salmon be sold? AquaBounty says it may take a year to raise enough fish to supply supermarkets. But certain retailers, including Costco, Whole Foods, Trader Joe’s, Safeway, Kroger and Aldi, said that as of now they do not intend to sell the fish. Still, with $85 million invested so far in the development of this unprecedented species, the company will likely be working hard in coming months to find viable retail channels for its fish. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4134365/the-first-genetically-altered-animal-is-approved-for-eating/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4134365/the-first-genetically-altered-animal-is-approved-for-eating/"},"headline":"The First Genetically Altered Animal Is Approved for Eating","datePublished":"2015-12-03T11:49:21.000Z","dateModified":"2026-02-22T13:04:21.572Z","description":"AquAdvantage grows twice as fast as regular salmon","url":"https://time.com/4134365/the-first-genetically-altered-animal-is-approved-for-eating/","keywords":[],"thumbnailUrl":"","author":[{"@type":"Person","name":"Alice Park","jobTitle":"Senior Correspondent","url":"https://time.com/author/alice-park/"}],"articleSection":"Health","image":[],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/4134365/the-first-genetically-altered-animal-is-approved-for-eating/","name":"The First Genetically Altered Animal Is Approved for Eating"}}]}] ```
