Abstract
Summary Persons suffering from celiac disease (CD) must avoid foods containing gluten or those contaminated with wheat, barley, or rye. This study was designed to estimate gluten contamination of cereal‐based foods available in Canada, whether labelled gluten‐free or not. About half of the 148 foods sampled were labelled as gluten‐free. According to R5‐enzyme‐linked immunosorbent assay (ELISA), twenty‐three cereal‐based foods (or 15%) contained more than 20 mg of gluten per kg, including sixteen regular and seven gluten‐free foods, the latter being the least contaminated. When used in combination with R5‐ELISA, AOAC‐ELISA (not detecting barley) was a simple and efficient tool to roughly estimate the nature of the gluten contamination, which was later confirmed by real‐time polymerase chain reaction for barley, and wheat/barley/rice. Rice‐, corn‐ or quinoa‐based foods were the safest for celiac patients. In addition to misleading food labelling for both gluten‐rich and gluten‐free foods, critical issues for persons with CD included foods made with oats or buckwheat (contaminated with wheat and barley gluten) in addition to those, such as breakfast cereals, specifically enriched with barley malt ingredients.

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 it
