Clean grain to avoid cross-contamination?

[tdc211]

I was given some whole organic corn. I want to run it through my mill and make flour. When asking about the processing of the corn, I was told, "Wheat on the other hand is processed on the same equipment as corn. We do have cleanout procedures which involves vacuuming clear the equipment, brushing/dusting, and finally flushing the system with 50-100 lbs of the material to be packed. I would not expect to find any wheat in the bag of corn you received. We do not test the finished products for the presence of unlike grains however." Would you trust that to be gluten free? Is there a recommended way to clean and dry before milling?

I would trust it, yes, to at least meet the <20ppm requirement for the FDA categorizing something as gluten free. But then, I'm not a super sensitive celiac and minor amounts of CC don't seem to cause a reaction in me. I think it is a positive sign that the source company was straightforward and gave detailed information about their cleaning procedures after running batches of gluten containing grains.

Yes, it sounds like it would be considered to be gluten-free based on their procedures.

I've been glutened by thinks marked gluten free, but with the warning about shared equipment. Contacted the company, similar clean out process to what you describe. I don't eat anything labeled that way anymore.

I already have the grain. Do you think rinsing it would work?

I should think it would. We're talking about whole kernel corn, right?

Yes. It is whole kernel.

I agree.  The warning about shared equipment is vague, but the implication is clear: They are not sure.  So the responsibility is on me.
