Evaluation of interventions for Salmonella in chickens using research synthesis and quantitative exposure assessment
Bibliographic record
Abstract
Systematic review-meta-analysis (SR-MA) was used to determine effectiveness estimates against 'Salmonella' concentration and frequency for different on-farm and processing treatments during broiler production. Results indicated that chilling may reduce 'Salmonella' concentration and frequency on broiler carcasses, but significant heterogeneity (p<0.1; I2>25%) precluded reporting pooled effectiveness estimates. These data were applied with those from other independently conducted SR-MAs and a scoping study (ScS) to generate inputs for a quantitative exposure assessment (QEA). The effectiveness of 2 individual farm and 6 processing interventions and a package of multiple interventions were compared within the Ontario context. A combination of farm and processing interventions pr04uced the largest reductions in 'Salmonella' concentration (99.87%) and prevalence (87.78%) relative to the baseline scenario. The ScS and SR-MAs provided a transparent and robust framework for selecting, evaluating and generating inputs for QEAs, however low methodological soundness and reporting of primary research prevented the full realization of their benefits.

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.
