Thanks for the feedback on Tully’s. I passed along your thoughts to Tully and here’s what she responded. (It sounds like they’re actively dealing with the problem you pointed out.)
From Tully:
We were using Sami’s bread and had a sign posted about the fact that it does not come from a dedicated gluten-free facility, so that the customer could make a decision on whether to eat it or not. A lot of our customers do not have celiac disease and were perfectly fine with eating bread that came from a non-dedicated facility. After the first person became ill, we tried to tell each and every customer where the bread came from. So many of our customers loved the bread so we continued using it while also trying to be completely transparent about it. 2 months later a couple more customers became sick and we decided it was time to discontinue using it completely. We stopped using the bread all together over 2 weeks ago until we find a 100% GF bread. We are very sad to have lost the trust of so many people, but I can assure them that everything in our bakery is made in the store with 100% gluten-free ingredients.

I have Celiac disease and had a severe gluten reaction last week after eating one of Tu-Lu’s paninis. I was shocked to find out that the bread they use for panini has been known to be contaminated with gluten for years, so contaminated that the bakery where it is made (Sami’s) don’t even call it gluten-free anymore. Over the last few months, Tu-Lu’s has had multiple posts on Yelp from people who got sick from their panini, yet they continued to carry it. They seem to not understand that it is not a matter of being “sensitive”; people with Celiac disease cannot eat ANY gluten. While Tully does make everything else in her bakery, it cannot be considered a gluten free facility if the same people are handling the bread and the other baked goods.

I think it is completely irresponsibly for a bakery that advertises its gluten-free facility to carry gluten containing bread. While I am glad that they have finally stopped making panini with this bread, carrying the bread for so long and causing illness in so many people with Celiac disease is inexcusable.
