I have noticed that many bags of cornmeal of the supermarket shelves now say they are manufactured in a facility that also manufacturers wheat. I even called several of the ones on the shelf that did not say that and they said that their product was also manufactured in a facility that manufactured wheat. I called Bob Red Mill's and Arrowhead to see about how they manufactured their "gluten free cornmeal" they said they manufactured it in on the same machine they processed wheat but they did clean the machine inbetween processing. They said they could not guarantee it free of cross contamination. I don't know about you - but I think that is misleading. When I buy a product that says gluten free I don't feel I should have to worry about cross contamination. I don't care if there is only a trace of gluten in the product - since my son is HIGHLY sensitive to gluten I can not take the risk. I have searched the internet and have yet to find a manufacturer of cornmeal that uses a dedicated grinder. Any suggestions? The only answer I have so far is to buy a table top grinder (about $250) and grind the cornmeal myself.
