Subway disputes study of chicken sandwich meat
Bibliographic record
Abstract
A study that conducted DNA tests on several chicken sandwiches from fast food restaurants found Subway's chicken breast contained only about half chicken. The chain calls the report "absolutely false and misleading." How much chicken is actually in your chicken sandwich?A study by the Canadian Broadcasting Corporation's consumer affairs show "Marketplace" says researchers conducted DNA tests on several chicken sandwiches from fast-food restaurants and found that Subway's chicken breast contained only about half chicken.The rest was mostly soy.Subway said the report was "absolutely false and misleading" and that its chicken is 100 percent white meat with seasonings, marinated and delivered to stores as a finished, cooked product.The study said DNA researcher Matt Harnden at Trent University's Wildlife Forensic DNA Laboratory tested the poultry in popular chicken sandwiches.Harnden and his team found that most of the scores were close to 100 percent chicken at McDonald's, Wendy's, A&W and Tim Horton's.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
