thank you rebekahc!!!!!!!!!! now i know why they say "when" and not "if' a reaction occurs ... because somewhere along the way an overworked, overtired mama is going to screw up. OMG i feel so bad on one level, but am so happy you have solved the mystery for us. in a way, the mystery was every bit as disturbing as the chain of events itself.
YES, of course it was the pizza dough! even after visiting the website for the phone number to call, i did not notice the tab "our products" and thought that they only offered one type of crust, sauce, and pepperoni, which is all i had ever seen at whole foods. when i called about Xcontam of sesame and peanut, i believe they were just placating me because it's pretty likely they do not make the sesame varieties in a different facility than the other types.
however, as soon as i saw the "our products" tab and noticed that there were different varieties, my heart started racing. i ran to the garbage (thankfully, in the melee wednesday night, my hubby didn't bother taking out the garbage) and dug through the vomit-filled bag (sorry, guys) to find that label (i had asked hubby to do it that night, but he said he didn't want to b/c he had thrown the vomit on top).
SURE ENOUGH it was the tuscan 6 grain crust, not the original crust we normally get!
talk about complacency ... i have been reading labels for 5 years now and outside of a couple not so close calls have never had a problem. this is the reason why i don't usually trust anyone but myself and my hubby to read labels for our daughter ... because mistakes DO happen.
this crust used to be hanging on the aisle by the frozen pizzas. recently i noticed it had moved, and they must have picked up this 2nd variety in the process. furthermore, there was only one pile of crusts, so i believe that they were out of the original and just had the one pile of tuscan crusts there (when i called whole foods this afternoon they told me that now they are out of the six grain and there is only the pile of original).
so, the mystery is solved, and now, of course, i feel absolutely horrible and afraid that i can no longer keep my daughter safe. usually i ask my hubby to double check things before he cooks them (i usually do when i am cooking) and that didn't happen either.
so, we know there is a breakdown in our system, which i guess is a lot more palatable then believing that she reacted to a trip to the playground or undisclosed cross contamination.
sesame is such a tough one to deal with, even though we have never had an issue in the past. even on the labeling of this particular product, they are responsible enough to label for may contains but do not deem sesame important enough to list as a contain (presumably because it is not top 8). i think my new mission will be to push for sesame labeling! it is just too pervasive, and it is totally hidden, usually near the bottom, of the ingredient lists.
thanks again, rebekahc ... we probably would have never revisited the crust had you not mentioned that there were other varieties. today my daughter's teacher had informed me that my daughter was freaking out because she thought she had touched her shoe (the same shoes she wore to the park the other night). upon telling my daughter that we had discovered that it was the pizza crust, i could see her face flood with relief. thank you!!!!!!!!!!
