A Canadian investigative consumer program ordered DNA analysis of several fast-food chicken sandwiches and concluded that Subway chicken was only half meat — with the other half soy.
The sandwich chain strongly rebuts the allegations, with a spokesman calling them "absolutely false" and calling for a retraction.
The tests were conducted by a DNA researcher at Trent University's Wildlife Forensic DNA Laboratory, for a CBC Marketplace episode dedicated to testing fast-food chicken dishes, and have not been independently confirmed.
On the episode, which aired Friday, the show found that dishes from McDonald's, Wendy's, A&W and Tim Horton's restaurants in Canada came in at 80 percent and 90 percent chicken DNA. (The meat was tested without any sauce or condiment, but seasoning and marinating would keep any chicken down from a pure 100 percent result, the CBC notes.)
But Subway's dishes were an outlier. "The oven roasted chicken scored 53.6 per cent chicken DNA, and the chicken strips were found to have just 42.8 per cent chicken DNA," the CBC reports. "The majority of the remaining DNA? Soy."
Last week, Subway told the CBC that Subway Canada "cannot confirm the veracity of the results of the lab testing you had conducted." Chicken strips and roasted chicken at Subway contain "contain 1% or less of soy protein ... to help stabilize the texture and moisture," the company told the CBC, and it promised to "look into this" with Subway's supplier.
On Wednesday, a Subway spokesperson more emphatically rejected the CBC's claims.
"The accusations made by CBC Marketplace about the content of our chicken are absolutely false and misleading. Our chicken is 100% white meat with seasonings, marinated and delivered to our stores as a finished, cooked product," the spokesman said in a statement sent to NPR. "We have advised them of our strong objections. We do not know how they produced such unreliable and factually incorrect data, but we are insisting on a full retraction."
The CBC Marketplace report raised a larger issue, beyond the question of Subway's chicken makeup.
In general, according to the report, the fast-food chicken tested had "about a quarter less protein" than home-cooked chicken, and sodium levels "seven to 10 times what they would be in a piece of unadulterated chicken."
"People think they're doing themselves a favour and making themselves a healthy choice" by picking chicken, a nutritionist told the CBC.
"But from a sodium perspective you might as well eat a big portion of poutine" — that is, the Canadian dish with french fries, gravy and cheese curds.
