I'm not sure why the store would tell you that, they do legally have to provide allergen information.
There is a bit more allergen information on their website, however:
Some of our arrangements and boxes of dipped fruit have crushed or sliced almonds, so there are nut products in our preparation areas. We cannot guarantee that a gift will not have come in contact with nuts or nut oil. We also have several arrangements and boxes that are dipped in peanut butter chocolate. We recommend that you take the necessary precautions based on any related allergies.
All Edible Arrangements products may contain or come in contact with items that contain milk products. We recommend that you take the necessary precautions based on any food allergies.
All chocolate is gluten free; however, our chocolate is manufactured in facilities that may also manufacture gluten-based products. Again, we recommend you take the necessary precautions based on any food allergies.
I'm sorry you got sick and that the store was less than helpful to you!
