That is a terrific powerpoint--
with the caveat presented toward the end, that is-- which is to say that when you look at a statistical sampling of the population with any particular food allergy, there ARE those individuals for whom "acceptable" risk from cross-contamination, even at low levels, is simply unacceptably high based upon their own history.
As long as the community, the industry, and the medical establishment does not IGNORE that those patients exist-- then I think that this is a tremendous step forward. But understand that defining what is acceptable for an "average" person with a peanut allergy.... CAN make the risks higher than ever for the 1% at the more sensitive end of the spectrum-- because "average" is what most people who encounter that person will think, and if they tune out what the person is trying to TELL them instead, that is bad.
