Abstract

fetched live from OpenAlex

Food labels represent an important tool for consumers to secure information about food product composition and facilitate informed decision-making regarding suitability. Canada and the USA have led the way, by means of adopting food labelling regulatory requirements with mandatory declarations, where thresholds of risk or evidence have been attained. In both countries, regulators have also set conditions for the discretionary use of certain statements on food labels. This chapter reviews food labelling regulatory practices in Canada and the USA, with an emphasis on their policy rationale and drivers of change.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
