Bacteriological and Histological Profile of Turkeys Condemned for Cyanosis
Bibliographic record
Abstract
Canadian Food Inspection Agency (CFIA) has adopted the term cyanosis to describe a category of condemnation for poultry that is dark but has no other condemnable lesions. Two case-control studies (n = 30 pairs; n = 65 pairs) of 18-wk-old tom turkeys were conducted. A case was defined as a carcass condemned by the veterinary inspector for cyanosis, and a control carcass was one that passed inspection. Microbiological tests were conducted on samples of Pectoralis major and Gastrocnemius lacteralis. A modified Rappaport Vassiliadis medium was used for Salmonella, and a Petrifilm method was used to assess aerobic counts, coliform counts, and Escherichia coli. The Salmonella (qualitative) test was negative for all cases and controls, and there were no significant differences between the aerobic counts, coliform counts, and E. coli counts of case and control carcasses. Two pathologists conducted a blind histopathological study: there were no lesions compatible with those of septicemia-toxemia, as defined by CFIA and the USDA, nor any significant histopathological differences between the skin, P. major, G. lateralis, kidney, liver, spleen, small intestine, pancreas, lung, and heart of cases and controls. The inter-rater agreement between pathologists ranged from good to excellent (Kappa = 0.7 to 1.0). In the absence of important lesions and microbial contamination, carcasses with this color change alone should be suitable for human consumption.

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.
