High occurrence of hepatitis E virus in raw pork liver and pork liver pâté produced in the Canadian province of Quebec
Bibliographic record
Abstract
The Hepatitis E virus is widespread throughout the world and causes sporadic cases of liver disease. In industrialized countries, its transmission is zoonotic, with pigs, deer, and wild boar being major reservoirs. Humans can be infected by ingesting raw or undercooked contaminated meat products. In the Canadian province of Quebec, HEV has been detected previously in pork liver and chops. In the present study, we analyzed 83 pork liver pâtés sold in local grocery stores and 79 raw pork livers obtained from Quebec hog processors. HEV RNA was extracted and detected by RT-qPCR. HEV RNA was amplified in 29% of the pâtés and 4% of the raw pork livers. Out of all amplified PCR-positive samples, only one showed a product during electrophoresis and was sent for sequencing. The resulting sequence matched a strain belonging to genotype 3 (HEV-3). This pilot study shows that HEV is present frequently in pork liver-based products in the province of Quebec.

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.
