Abstract

fetched live from OpenAlex

Abstract In North America in 2006, outbreaks of pathogenic Escherichia coli and Salmonella in spinach, lettuce and tomatoes sickened over 700 people and caused four deaths. These high‐profile cases are only the tip of the iceberg, however, and many people are affected by contaminated produce each year. Douglas Powell and Ben Chapman reveal why current food safety programmes in the USA have not eliminated contamination and suggest how an industry led by producers could spearhead programmes to mitigate the risk of future outbreaks.

Full frame distilled prediction

Teacher imitation

Not 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.
