How is “verified gluten-free” actually proven—and why can a single test result be misleading?

In Episode 7 of Trust Your Oats, Trust the Batch, Dale Tenhulzen breaks down what batch-level verification really means in gluten-free oats. The episode explains how modern gluten testing works, why the industry relies on ELISA methods, and how standards such as 20 parts per million became the legal definition for gluten-free labeling—while leading certification programs often require stricter limits.

A key focus is the challenge of kernel-based contamination in oats, where gluten is not evenly distributed. Because contamination can occur in “hot spots,” averages can look safe while individual servings may not. The episode explores why sampling strategy matters as much as the test itself, and why multiple subsamples and serving-level thinking provide a clearer picture of real-world risk.

Listeners also learn why verification must be layered: internal testing at multiple checkpoints, external confirmation through accredited third-party labs, and ongoing certification oversight that includes audits and independent surveillance testing.

Trust the Batch explains how confidence is built batch by batch—not through assumptions, but through evidence.
