Placeholder. A baby cereal brand puts a QR code on every single bag linking to that exact batch's toxic-element test results — not a general 'we test for heavy metals' claim, but a scan-your-bag-specifically system, tested against a 551-toxin standard modeled on EU limits.
What we've found so far: Little Spoon's organic baby cereal includes batch-specific QR verification against 551+ toxins/contaminants using EU-inspired heavy-metal/pesticide/glyphosate limits; it's also the first Clean Label Certified multigrain baby cereal.
Open research: Actually scan a real product's QR code and document what data is shown; compare Little Spoon's testing rigor claim against FDA baseline requirements.
