Should I be concerned about using the same dish/hand towels and pot holders as family members in my household who handle gluten-containing food?
The risk of cross-contact in a kitchen where both gluten-containing and gluten-free foods are stored and prepared is real. For instance, if a pot holder is being used on a gluten-containing fruit cobbler and the cobbler rises up to or over the top of the baking pan, there is a chance the pot holder may inadvertently come into contact with the food. If a bit of gluten is on the pot holder, and you later use it in the same way on your gluten-free cobbler, cross-contact could result.
On the other hand, if sufficient care is taken to be sure that the pot holder does not come into contact with the food, there should be minimal to no risk. Using separate pot holders is a good idea and won’t break the bank.
One should note the type and number of gluten-containing items being made in a home kitchen. Keep in mind that younger children, others in the household, or visitors who have less understanding of dietary needs may not be as vigilant about avoiding cross-contact as you are.
Regarding dish towels, the same principles apply. If others in the household are using kitchen towels only on dishes or hands that have been thoroughly washed, the risk is minimal to none. Otherwise, using separate towels, or even paper towels, is a good idea.
