According to tests performed at Trent University in Canada, the company’s chicken strips and oven-roasted chicken contained just 43% and 54% chicken DNA, respectively, consisting otherwise of soy and other filler ingredients. The sandwich chain denies the allegations. The investigation, which aired last week on the CBC program [_Marketplace_](http://www.cbc.ca/beta/news/business/marketplace-chicken-fast-food-1.3993967)_,_ included DNA tests of chicken products purchased from several fast-food chains in Canada. Researcher Matt Harnden said on the show that his lab, which tests meat samples for both industry and government, could provide a “rough estimate” for the ratio of chicken DNA to other ingredients. (The episode can be [viewed here](https://www.youtube.com/watch?v=xd3Trr8Xrdc&list=PLeyJPHbRnGaZmzkCwy3-8ykUZm%5F8B9kKM&index=2) on YouTube.) Most chicken samples tested—from McDonald’s, Wendy, Tim Hortons and A&W—contained between 85% and 90% chicken DNA. Fast-food chicken wouldn’t be expected to be 100% bird, Harnden said, because of seasoning marinades, and other ingredients that are likely added in the preparation process. But the chicken content of the samples from Subway was consistently low even after repeated testing, and the tests showed that much of the remaining DNA was from soy protein. “Assuming the data is right, that is a surprisingly large amount of soy,” says John Coupland, president of the Institute of Food Technologists and a professor of food science at Penn State University, who was not involved in the testing. Elevated soy levels might be expected in reconstituted meat products, in which meat is ground up and stuck back together with binder ingredients, says Coupland. “But even then, 50% is high,” he says. “And it’s astonishingly high for something that you’re supposed to think is a real, whole piece of chicken.” Subway Canada said in a [statement](http://www.cbc.ca/marketplace/blog/company-responses-chicken) to _Marketplace_ that the company could not confirm the veracity of the lab results, but was “concerned by the alleged findings.” Subway chicken strips and oven-roasted chicken contain less than 1% of soy protein, the statement reads, which is used to moisten and stabilize the meat’s texture. “We tested our chicken products recently for nutritional and quality attributes and found it met our food quality standards,” the statement reads. “We will look into this again with our supplier to ensure that the chicken is meeting the high standard we set for all of our menu items and ingredients.” A statement provided to TIME by Subway headquarters in the United States reads in part: “Our chicken is 100% white meat with seasonings, marinated and delivered to our stores as a finished, cooked product. We have advised \[_Marketplace_\] of our strong objections… \[and\] we are insisting on a full retraction.” Subway’s U.S. site contains a list of [ingredients](http://www.subway.com/en-us/menunutrition) used in its chicken products. For instance, the chicken breast strips contain “boneless skinless chicken breast with rib meat, water, 2% or less soy protein concentrate, modified potato starch, sodium phosphate, potassium chloride, salt, maltodextrin, yeast extract, flavors, natural flavors, dextrose, caramelized sugar, paprika, vinegar solids, paprika extract and chicken broth,” according to Subway’s website. Coupland says that a high soy content that turned up in the _Marketwatch_ study may be concerning to some with allergies. Most people with an allergy know to avoid fast food, since traces of soy are found in so many processed foods, he says. “But if people think they’re getting pure chicken and they’re in fact getting a mouthful of soy, that’s potentially dangerous.” Nutrition tests performed for _Marketplace_ also found that fast-food chicken contained 25% less protein than home-cooked samples, and between 7 to 10 times the amount of sodium. Subway’s chicken strips and oven-roasted chicken are both available at United States locations, but, according to the company’s website, their ingredients vary slightly from their Canadian counterparts. Both countries include soy protein in their chicken strips, but only the U.S. version specifies that it’s present in quantities of 2% or less. And while Canada does include soy as an ingredient in its chicken patty used for the oven-roasted chicken sub, the United States does not. A panel of taste testers on _Marketplace_ rated Subway’s chicken as their least favorite among the fast food options, noting that the samples tasted “saltier” and “more artificial” than those from other chains. One panelist commented that Subway’s chicken strips tasted like “more flavor than actual chicken.” The fast-food chain, which prides itself on offering healthy alternatives to burgers and fries, was hit with a rash of bad publicity in 2014 when customers complained that azodicarbonamide, a food-grade material also found in yoga mats, was used in their bread. Subway removed the chemical, and pledged the next year to [remove all artificial ingredients](http://time.com/3908918/subway-artificial-ingredients/) from its food in North America by 2017. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4687113/subway-chicken-fast-food-filler-2/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4687113/subway-chicken-fast-food-filler-2/"},"headline":"Subway Denies That Its Chicken Is 50% Filler","datePublished":"2017-03-01T16:00:21.000Z","dateModified":"2026-04-13T09:05:00.061Z","description":"Following an investigation into the chain's meat","url":"https://time.com/4687113/subway-chicken-fast-food-filler-2/","keywords":["motto","Chicken","subway","Fast Food","Food Safety","protein","Diet & Nutrition"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltcaab8ca7fd987ee3/6988bc87bc6cfc58d33e05a7/subway-chicken-sandwich.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Amanda MacMillan","jobTitle":null,"url":"https://time.com/author/amanda-macmillan/"}],"articleSection":"","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltcaab8ca7fd987ee3/6988bc87bc6cfc58d33e05a7/subway-chicken-sandwich.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Three Foot Long Subs","caption":"Three Foot Long Subs","creditText":"LauriPatterson—Getty Images/iStockphoto","representativeOfPage":true}],"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":"/tag/motto/","name":"motto"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/4687113/subway-chicken-fast-food-filler-2/","name":"Subway Denies That Its Chicken Is 50% Filler"}}]}] ```
