Abstract
Ochratoxin A (OTA) is a mycotoxin found in multiple agricultural commodities worldwide. OTA causes renal toxicity in certain animal species, but there is little documented evidence of adverse health effects in humans. Until recently, few nations have established regulations on maximum levels for OTA in commodities. The application of regulations may cause economic loss to food producers, which should be considered alongside potential health benefits from enacting such regulations. We evaluate the potential economic impacts of the recently proposed OTA maximum limits (MLs) for foodstuffs by Health Canada. Potential costs to Canadian food producers and nations exporting to Canada are estimated using data on reported proportion of foodstuffs exceeding OTA ML levels, and market data from the Canadian Importer's Database and the United States Department of Agriculture Global Agricultural Trade System. If the proposed OTA MLs are enforced, estimated annual losses to Canadian food producers could exceed 260 million Canadian dollars (CD), based on proportion of products expected to have OTA levels exceeding the MLs. Wheat and oat producers would experience the greatest proportion of economic loss. The United States is the largest exporter to Canada of foods that would be subject to the proposed MLs, and would experience an estimated annual loss of over 17 million CD; primarily in the infant food, breakfast cereal and raisin industries. The countervailing health benefits of such OTA standards are unclear. These potential health and economic implications should be considered by policymakers when setting regulatory standards on food safety.

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
