Ciguatera fish poisoning in an international ship crew in Saint John, Canada: 2015
Bibliographic record
Abstract
An international ship crew presented for medical care in Saint John, New Brunswick, following rapid onset of gastrointestinal and in some cases neurological and cardiac symptoms after a common fish meal.Ciguatera poisoning was identified as the cause of illness.This report describes the public health investigation and management of this incident, including collaboration between the implicated provincial and federal authorities. Case presentationOn April 11, 2015, nine male crew members of an international cargo vessel docked in Saint John, New Brunswick (NB) presented to the emergency department at the Saint John Regional Hospital (SJRH) with gastrointestinal symptoms (nausea, vomiting, diarrhea and abdominal cramps).Other significant symptoms included dizziness, weakness and peripheral extremity paresthesia.When examined, several of the men were further found to have hypotension and bradycardia.All were admitted for intensive care-level monitoring and management, including continuous cardiac monitoring, atropine for bradycardia, antiemetics and intravenous rehydration.Within a few hours, five more crew members presented with the same symptoms and were also admitted.

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.
