A generic model for risk-based food inspection in Canada: assessment of initial biological hazards and risk ranking for inspection
Bibliographic record
Abstract
Risk-based inspection provides a framework whereby inspection resources can be prioritized and targeted towards foods that pose the highest risk to human health. To provide a risk assessment of the initial biological hazards associated with foods consumed, criteria related to hazard identification, hazard characterization and exposure assessment were developed for all foods inspected by the Canadian Food Inspection Agency.Using Canadian scientific data, food-pathogen pairs most responsible for foodborne illness were developed and ranked. To characterize the overall population burden of these food-pathogen pairs, a model adapted from the European Food Safety Authority (EFSA) was developed which incorporated criteria related to pathogen characteristics and probability of exposure of humans by food.The top risk-ranked food-pathogen pairs were Campylobacter spp. and poultry, pathogenic Escherichia coli and beef, Salmonella spp. and poultry, Salmonella spp. and produce, and Campylobacter spp. and dairy.

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.
