Two automated pipelines screening South African packaged foods against sodium limits agree on only 69.5% of final verdicts
A YOLO26s-plus-OCR pipeline and an independent Qwen2.5-VL 7B pipeline screening 442 South African packaged foods against R214 sodium limits agreed on only 69.5% of final verdicts, with 93.9% category agreement.

When 442 South African packaged foods were screened by image against R214 sodium limits, two automated pipelines agreed on only 69.5% of final verdicts (307/442), with 93.9% agreement on category classification; insufficient-evidence cases were routed to REVIEW rather than forced to a verdict.
Previously such screening relied on manual checking of package labels, with no quantified cross-check of agreement between two independent automated pipelines.
The result was self-reported by Mayimunah Nagayi and four others: one pipeline used YOLO26s region detection plus OCR, the other was an independent Qwen2.5-VL 7B pipeline, and the agreement rates above were measured by comparing the two.
The result is author self-reported, not peer-reviewed, and not yet reproduced by any third party; it comes from an arXiv preprint (arXiv:2609.15427) submitted September 14 and revised as v2 on September 15.
