The researchers knew that no piece of chicken would measure 100 percent pure chicken DNA, since the process of seasoning, marinating, and processing meat reduces that somewhat; only an "unadulterated piece of chicken from the store should come in at 100 percent".
"Test results from laboratories in Canada and the USA clearly show that the Canadian chicken products tested had only trace amounts of soy, contradicting the accusations made during the broadcast of CBC Marketplace", Subway representatives said in a news release. What you would also most likely expect is that the chicken is made of chicken, right?
The sandwich chain, which has become one of the world's most popular fast-food brands over recent years, has vowed to look into the matter.

"The stunningly flawed test by Marketplace is a tremendous disservice to our customers", Subway President and CEO Suzanne Greco said. Chicken from other fast-food chains, such as McDonald's and Tim Hortons, did not have such high levels of plant DNA. As a rebuttal, the company sent its chicken to two independent labs - one in Canada and another in Florida - and surprise, "the results from both labs found soy protein below 10 ppm, or less than 1%, in all tested samples". However, the study methods have not been released - only the conclusions and percentage results.
When you go into a Subway restaurant and order a chicken sandwich, what are your expectations? That's why we took extra caution to test and retest the chicken.
The CBC said its tests were done by credible, independent experts and added "Subway has yet to provide any explanation for the DNA test results obtained by CBC". However the ingredient list it forwarded to CBC News lists soy protein as a constituent of the chicken.
