Anyway... so what caused it? Everything I ate was stuff that was totally safe, unless my individual pb had been contaminated (which I didn't think was possible since I'd eaten some other containers of it from the same box.) My crackers were from an opened package from home, I'd just put some in a container. My cheese was wrapped, and I'd been eating those cheese sticks from that package without problems.
I wracked my brains and then suddenly it came to me. I had forgotten to bring in a spoon from the car and it was too cold (i.e., I was too lazy) to wait for the elevator, and walk all the way out to the parking lot. So I used the spoon my dd had been using for her ice cream. I rinsed it under the water and sort-of rubbed it with my fingers, but didn't really wash it. I'm sure that's what it was because when I asked her what she'd had not only did she have cookie dough ice cream but then some of her toppings were gluteny -- cookie dough butter, oreos, and something else. I'm sure that the oil from all that was still on the spoon.
You'd think after a couple of years at this I'd be smarter!
Lesson for the rest of you: Don't be lazy like I was -- go ahead and walk down to the car and get your own spoon! or, really really wash the other spoon, in soap and hot water. oy...
