Understanding Gluten Contamination

10-days-of-gluten-free

It’s day five of the 10 Days of Gluten Free blog hop!  I am covering topics related to getting started on the gluten free diet.  Be sure to visit the other participating blogs listed at the end of this post.  Each one is covering a different gluten-free topic and has a great giveaway you can enter.

Understanding Gluten Contamination

Gluten can show up in foods by being part of the ingredients.  It can also show up through cross contamination (or cross contact) during the processing or preparation of foods.

When gluten-containing foods are processed, those foods can leave gluten behind on the equipment, particularly dry foods such as cereals and baking mixes.  In addition flour and other fine particles can become air born and hang in the air up to 24 hours before settling on surfaces.

When food is prepared in a kitchen that contains gluten, whether at home or restaurant, there is a risk of that food becoming contaminated.

Contamination During Processing

Equipment:  Some companies clean their equipment between various products that they run.  Other companies use separate equipment for allergy free products, but the equipment is part of the same facility.  A few companies have a separate manufacturing facility for gluten or allergy free items.  And, of course, there are companies who produce only gluten-free foods.

Labels:  When you start reading labels you will notice that some of them contain a statement at the end of the ingredient information that communicates the fact that the food was processed on equipment or in a facility that contains other allergens.

These statements are not required by law nor are they regulated.  That means that a product without a statement may still be produced on equipment with other allergens (including wheat).  It also means that just because a statement indicates that a food was produced in the same facility as other allergens, it does not mean that it is not produced on the same equipment.

I go into a little more detail about  warning statements in the post Reading Labels Part 3.

Contamination During Preparation

If you think of a kitchen like a food processing line, the risk of contamination is the same.  Anything that gluten comes in contact with can potentially contaminate gluten-free food.

On Monday I will be talking more about your kitchen.

    Good information. Thanks!

  2. I agree, we are still relatively new to this, but even we see the red flags all over it. My 7 year old gluten free girlie will not be eating this one! Thank you for the info. It was a great post!

  3. Thank you for the information on cross contamination. It is so hard to get others to understand that cross contamination is just like picking up that slice of “gluten” and eating it.

  4. I am enjoying all of the information of the 10 days of Gluten-Free!

  5. most informative and helpful…
    thanks!

  6. Boy, don’t get me started on this subject. Going into any restaurant, my heart starts a pumping and some anxiety starts in, worrying about is this place safe, will they understand my allergic reaction, just repeating myself again about how I can’t eat this and that. And please don’t cross contaminate!

    I wish the servers were taught to say, ‘ Hi I’m _____, your server. Welcome to ____ and before I start is there everyone here that has any food allergies I need to know about.’ Wouldn’t that be wonderful!!

  7. Bonnie says:

    Thanks for the info that I need to be more aware of!

  8. Jeannie Parker says:

    Thank you, all of this information has been very helpful.

  9. I educate all my friends on how easy cross-contamination can occur. Things like using a knife to spread mayo on their gluten laden bread, and then sticking it back in the jar. Or at a buffet line, using a spoon from the gluten-free potato salad in the gluten laden macaroni salad, and then putting it back into the gluten-free potato salad. While these may seem like innocent acts, they do not realize the risks associated with their actions for those of us with food allergies.

  10. We had to learn how to make sure cross-contamination does not happen in our kitchen – it took us about a year or two before we now almost automatically make sure of that. (I have gluten-intolerance – my DH can eat “normally”.) For example, we have separate butter dishes. I hate picking up an interesting product, only to see “produced in a facility with wheat, soy, etc …, because it means I probably can’t eat it. Once in a while I will take a chance and buy the product and just hope I don’t get sick!

  11. GREAT INFO THANKS

  12. If only all the companies clearly understood the word “cross-contamination”!!

  13. jennifer s says:

    Great info! Still learning, and eating out is one of the hardest parts about being gf.

  14. Hopefully some day soon, there will be safe restaurants across the US. Until then, we have to be very careful.

  15. Thanks for info

  16. Natalie says:

    My gi symptoms are disappearing but more symptoms are taking their place…like neuropathy and shaking hands. I have just had blood tests to determine my levels of vitamins and hormones. I am not sure, but I do believe that I get cross contamination. No one in my family except me has celiac disease. Thanks for the info. I hope others and I can learn from your advice and get better!!! (gluten free ~ 2 mos)

  17. I really don’t understand why allergy warnings are not mandatory.

  18. Colleen M. says:

    It is so important to educate your entire family about cross contanimation in the kitchen if everyone is not GF. Everything from cutting boards, strainers, separate toasters, “condiment” jars, butter dish, etc. I continue to educate my family at EVERY opportunity!

  19. We are all gluten free at home, and it makes cross contamination a non-issue.

  20. Wendi S says:

    Great information!

  21. Angel R. says:

    Wonder if we will ever lose the fear of cross-contamination … (sigh)

  22. Cindy W. says:

    Great tips!

  23. Keena Roberts says:

    Thank you for the info. We are new to the gluten free diet.
