Domino's disclaimer that their gluten-free pizza crust is not meant for those with Celiac Disease because they can't guarantee no cross-contamination, I figured I'd put in my two cents.
My first thought is...
You think a chain with thousands of locations can make a guarantee there will be no chance of cross-contamination? And that all employees will follow the proper procedures 100% of the time? Of course not. That's just asking for trouble...
In the sue happy world we live in, making a guarantee would mean people can sue for getting sick. Or for not getting sick. What's the chain gonna do, ask to see a biopsy slide showing damage? If someone sued the chain, they would likely give in, settling out of court, so they don't get bad publicity.
I, for one, am happy they have this disclaimer. They leave the choice of whether or not to risk the chance up to the consumer rather than making a false guarantee.
I think just about any restaurant offering gluten-free items will have a warning that there is a chance of cross-contamination. If they don't, I think they are setting themselves up for problems. Even the most experienced chef can't make a guarantee.
I've even read comments online about those with Celiac Disease saying they themselves have made mistakes in their home with gluten eaters and have glutened themselves. If it can happen in your own home, it can happen anywhere.
In conclusion, I think people need to realize that any restaurant without a dedicated gluten-free kitchen is going to have a disclaimer that gluten may contaminate the food. There's just no way around it... unless of course, you expect them to outfit all Domino's with a special gluten-free kitchen with separate ventilation to eliminate any possible risk of flour settling on your food.
