Subway swears its chicken is chicken and releases its own study

After testing the poultry in six popular chicken sandwiches, DNA researcher at Trent University's Wildlife Forensic DNA Laboratory, Matt Harnden found that most of the meat had "very close" to 100 per cent chicken DNA.

DNA tests revealed that the chicken used in Subway sandwiches is far more adulterated than the chicken used by other fast food chains. The rest was made up of soy.

Subway said lab tests it commissioned show its chicken had only trace amounts of soy.

CBC in Canada said it conducted a study that showed oven-roasted chicken patties at Subway average 53.6 percent chicken DNA.

While fast food samples aren't expected to meet 100 per cent chicken DNA score due to seasoning and processing, Subway's score is alarming. 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 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. Originally, the CBC only tested one sample from each location, so this was by no means a scientific study.

Subway has shared the results of the independent tests with CBC and the lab that conducted the test. Subway is demanding a retraction and an apology.

You might have thought chicken is the healthiest choice when ordering a Subway sandwich; however, an investigation by CBC Marketplace into what's in the meat might leave you unsettled.

"The stunningly flawed test by "Marketplace" is a tremendous disservice to our customers", said Suzanne Greco, Subway president and chief executive, in a statement issued Wednesday night. Each piece of chicken was broken down into three smaller samples, which were individually tested.
