Analysis of characteristics of national food poisoning events from 2002 to 2012 and discussion on precautionary measures
Bibliographic record
Abstract
Objective To investigate the characteristics of the food poisoning events from 2002to 2012and discuss the precautionary measures.Methods Descriptive analysis was used to analyze the general features,seasonal distribution,causes and occurring places.Results There were 3 546documented food poisoning events from 2002to 2012,resulted in 121 034cases,in which 2 234died.Most annual cases were reported in 2006while in 2003most death cases occured.The 3rd quarter of the year has the highest incidence rate,and the main causes were microbiological pathogens.Most cases occurred at dining hall.However,highest mortality rate of food poisonning events happened at home.Conclusion The serious situation of food poisoning requires enhancing publicity for food safety,strengthening survillance and prevention,launching the training for food poisoning emergency events and establishing the food risk-assessment frame.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
