REDUCTION OF CAMPYLOBACTER IN CHICKEN LIVERS USING A LOW ACID PROCESSING AID
Bibliographic record
Abstract
Liver has become a prime source for Campylobacter outbreaks and products are needed to allow processors a more efficient way of controlling foodborne pathogens. Campylobacter reductions in livers treated with a low pH processing aid (CMS PoultrypHresh), with and without a surfactant (PoultrypHresh Plus) were studied. Chicken livers (n=13/treatment group) were individually inoculated with a C. coli marker strain (107) and each dipped into sterile cups containing 100 mL of water, PoultrypHresh or PoultrypHresh Plus for 15 s, removed and allowed 5 s to drain. Each liver was placed into 50 mL buffered peptone water and hand shaken for 60 s; controls (n=10) same procedure, no treatment. Rinsates were serially diluted and plated onto Campy Cefex agar with 200 ppm gentamicin. Plates were incubated for 48 h at 42°C microaerobically, colonies counted and log transformed. Procedures were replicated 3 times. Significant reductions in treated compared to untreated for PoultrypHresh and PoultrypHresh Plus was 98.1% and 99.4%, respectively and with no change in appearance. Treating with this product may allow processors to meet rising performance standards on poultry livers.

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.
