CROSS CONTAMINATION

When cross contamination is such a big thing with gluten free eaters it sounds to others that we are being princesses or high maintenance or a nuisance that they can complain about after you leave. Which is unfortunate. Although I have experienced this in the past I have to say that because of a family in the new town I live in has changed my opinion completely.

I had a wonderful experience when I moved to a different area of Canada when I was invited to eat at a family’s home that I didn't know. Wanting to meet new people and knowing that they were so friendly and kind I accepted...and to my delight. They made me feel so welcome even having to make sure nothing I ate was gluten filled. We ate a delicious meal and had great conversation. They taught me about the area and helped with places to apply to and many amazing attractions to see!
I thank them for their hospitality and giving nature. I even left with two bags full of fresh garden potatoes, a bag full of fresh garden carrots and three large squash, which I used up not wasting a single morsel. She even offered more garden veggies to me! Although I wanted to I declined...I didn't want to look greedy.

CROSS CONTAMINATION
Not only must we be cautious about the ingredients in gluten free food, we must also be aware of the possibility of cross contamination.
What is meant by "cross contamination" in the context of celiac disease? Cross contamination is the process by which a gluten -free product loses that status because it comes in contact with something that is not gluten-free.
At home the following practices will go a long way towards avoiding cross contamination:
A celiac should have their own butter dish and a cutting board that is used for gluten free foods only.
A celiac should have their own toaster if possible. A toaster oven, where the rack can be removed and washed if others have used it may be a good alternative.
If it is not practical to have a section of the counter top set aside for preparing gluten-free food only, always make sure that the counter space you are using to prepare gluten-free food is freshly washed to ensure it is free from crumbs or flour dust.
Do gluten-free baking first, and have it well wrapped and stored before doing anything with regular flours. Flour dust (in the air) from regular flours could settle on the gluten-free products, thus contaminating them.
Note: Although this doesn't fall into the cross contamination area, it is worth noting that a celiac should take precautions against breathing in flour dust when using other than gluten-free flours. Flour dust that settles on the nasal passages may eventually get swallowed and end up being digested.
Use clean utensils and avoid "double dipping" - knives or spoons are OK the first time, but once they have touched food with gluten, they can contaminate the food in the container if used again. If it is too difficult to train other family members in this regard, it would be wise for the celiac to have their own jar of jam, peanut butter, mustard, etc.
Be especially alert and cautious when you have guests helping in the kitchen - they will not have your gluten awareness. Also, it is when you are otherwise distracted that you are more likely to make a gluten error.
When making sandwiches, do the gluten-free ones first - otherwise be sure to wash your hands after touching regular bread and before touching gluten-free supplies.
Make sure any pots, utensils, etc. that are used for other foods are thoroughly scrubbed before using for gluten-free foods. In the case of something like muffin tins, paper liners may be a worthwhile consideration.
It is best to have a separate set of utensils with porous surfaces, such as wooden spoons, for your gluten-free baking. These utensils might retain some gluten particles after cleaning.
If using lentils, be sure to meticulously pick them over before putting in the pot to cook. Even if you buy them packaged, it is not uncommon to find kernels of wheat or oats (or pebbles) in with the lentils.
Away from home, be aware of sources of cross contamination:
Products in bulk bins can become contaminated by using the scoops in more than one bin. There is no assurance that the other customers will be as cautious as you. Also, flour dust in the air around these bins can cause a problem.
At the deli counter, where gluten-free meats are being cut using the same utensils without cleaning in between. Also, the cut meats often overlap on the counter.
Buffet lunches, where the chef tests the temperatures in all the dishes using one thermometer, or spoons are used for more than one dish.
In product production where a gluten-free product is not produced on a dedicated line. Cereals and candy bars that have gluten-free ingredients may be produced after a non GF item without having the equipment cleaned thoroughly in between.
French fries cooked in oil where battered foods have been fried.
Meat cooked on a grill which hasn't been cleaned after cooking regular food with gluten.
Milling of gluten-free grains on equipment that has been used for regular grains and has not been thoroughly cleaned.
