I posted the link to Trader Joe's GF food list.

I recieved quite a few similar warning-type responses.  All the
responses can be summed up in this well written reply from Susan Ivey:

<Just one problem- the list is not accurate. I myself shop at Trader
Joe's weekly and LOVE it. However, I have found their GF list to be full
of inaccuracies. My advice: 1) Use the list as a starting point, but read
labels too! Usually the problem will leap out at you from the label. 2)
try only one new thing from the list at a time- that way if you have a
reaction you will be able to pinpoint the cause.>
