Earlier this week, CBC reported that the lab found that Subway's chicken was only about half animal protein. "The allegation that our chicken is only 50% chicken is 100% wrong", said SUBWAY President and CEO Suzanne Greco.
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.
So Subway released its own study conducted by two independent laboratories in order to test the chicken from Canada, the Post reports. "Soy protein concentrate" is listed as an ingredient in the chicken strips, and "soy protein" is an ingredient in the chicken patty. 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. "The company is demanding a retraction and apology".
The "Marketplace" program "stands by its report", CBC wrote in its own defense on Wednesday.

Results were much worse for the two Subway samples. Company spokesperson Kevin Kane said in the release that the "alleged test results" shown on the program are "false and misleading".
DNA analyses are useful for identifying outright food fraud - like fillets of cheap Asian catfish being passed off as more expensive cod. The lab also retested these samples a second time.
But DNA is not traditionally used in food science to indicate percentage mass.
The results showed that the filets contained just 53.6 percent chicken DNA.
Chicken from other fast food chains including Wendy's and McDonald's came in close to 100 percent chicken. In response, Subway sent samples of the Canadian products that "Marketplace" claimed contained 50 percent soy protein to Maxxam Analytics in Canada and Elisa Technologies, Inc., in Florida.
