I never trust that type of labeling. What does "effective effective cleaning practices" mean?
We don't, either-- not with some allergens, that is.
Cleaned lines are one of those things that SOME people with higher thresholds
may tolerate. So it is really individual-- we have had pretty good luck trusting these kinds of processing statements (in the past, I mean) with:
soy
wheat
milk
and not-so-good-luck with egg (depending upon what the manufacturer MEANS by "cleaned"-- and this involved phone calls to determine, btw), but now that DD's egg threshold is higher, she can do a lot of the things that used to be off-limits.
With nuts, we've been burned
every time-- and mostly, we find out after the fact that there are shared lines. She
always knows.
