Well, I really have no idea. I haven't had anything Thai Kitchen in my house since DD reacted to stuff of theirs that they claimed
COULDN'T be peanut-contaminated-- that was almost a decade ago. On the other hand, that may point to a larger manufacturing issue there, as they handle a LOT of super-potent allergens in dust/powdered form that makes cross contamination a bigger problem even in other product lines. For reference, the product in question was a coconut milk that was in a
separate building from their dry/powder mixing and packaging which is where the peanut powder/dust was.
I don't react to Better-than-Bouillion, though, and that's cleaned/shared lines, I think. I do sometimes react to Worcestershire, it just depends on how much and how full my allergy cup is otherwise.
My threshold fluctuates a bit, so I wouldn't say that my experiences are terribly reliable.
