Abstract
BACKGROUND: On 8 September 2006, 3 Georgia residents presented with symptoms of food-borne botulism, a potentially fatal illness caused by Clostridium botulinum neurotoxins. METHODS: Investigators reviewed medical records and interviewed patients and family members. Foods from patients' homes and samples of the implicated commercial beverage were tested for botulinum toxin and C. botulinum by standard methods. RESULTS: The patients presented with cranial neuropathies and flaccid paralysis; all patients required mechanical ventilation. The 3 Georgia patients had consumed carrot juice from the same bottle before illness onset. An additional case in Florida and 2 in Ontario, Canada, were subsequently identified in patients who had consumed carrot juice. Serum samples obtained from 5 patients tested positive for botulinum toxin type A-in one patient, 12 days after illness onset, and in another patient, 25 days after illness onset. Carrot juice produced by 1 manufacturer, recovered from patients' homes in Georgia, Florida, and Ontario, yielded type A toxin. The juice contained no added sugar, salt, or preservative; inappropriate refrigeration likely resulted in botulinum toxin production. CONCLUSION: This outbreak was caused by commercially produced, internationally distributed carrot juice that was contaminated with botulinum toxin. When toxemia persists, treatment for botulism should be considered even if diagnosed weeks after illness onset. The implicated pasteurized carrot juice had no barriers to growth of C. botulinum other than refrigeration; additional protective measures for carrot juice are needed to prevent future outbreaks. The US Food and Drug Administration has since issued industry guidance to reduce the risk of C. botulinum intoxication from low-acid refrigerated juices.

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 it
