Application of a Gas-phase Hydroxyl Radical Treatment to Inactivate Salmonella Enteritidis and Campylobacter jejuni on Table and Hatching Eggs
Bibliographic record
Abstract
The following thesis developed a gas-phase hydroxyl radical process technology as an intervention against Salmonella Enteritidis and Campylobacter jejuni associated with shelled eggs, without negatively affecting shelf-life or hatchability. The continuous treatment is based on UV-C mediated degradation of hydrogen peroxide (H2O2) and ozone (O3), generating antimicrobial hydroxyl radicals. Trials evaluated interactions between H2O2, UV-C, and O3, in terms of pathogen reduction and egg quality metrics. An optimized treatment of 2% v/v H2O2, 20 ppm O3, and 19mJ/cm2 UV-C supported a 5.01 log10 CFU/egg reduction of S. Enteritidis and 4.87 log10 CFU/egg reduction of C. jejuni. No negative effects on egg quality (Haugh unit, yolk index, albumen pH, yolk pH) or shelf-life were observed. The optimized treatment did not negatively impact hatchability of hatching eggs. Ultimately, the research has demonstrated the potential of gas-phase hydroxyl-radicals to reduce the incidence of S. Enteritidis and C. jejuni in egg production.

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.
