Polyaromatic Hydrocarbons of Smoked Cured Muscle Foods Prepared by Canadian Tl'azt'en and Llheidli T'enneh First Nation Communities
Bibliographic record
Abstract
Tl'azt'en and Lheidli T'enneh First Nation communities have traditionally used smoking, drying, and salting of fish and game as preservation methods to enhance food security. Our results showed that levels of 16 polycyclic aromatic hydrocarbons (PAH) were significantly higher in smoked salmon samples compared to moose meats, and further, that PAH contents were also dependent on the duration of smoke processing. Benzo[a]pyrene (BaP) was not detected in fresh or partially smoked foods, but was present in both fully smoked moose (1.4 μg/kg) and fully smoked salmon (3.6 μg/kg) meats, respectively. The total concentrations of PAH present in fully smoked meats using traditional smoke processing methods employed by Tl'azt'en and Lheidli T'enneh nations indicate that a risk assessment is required to determine the safety of these smoke-processed foods.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
