Are food products becoming more dangerous for allergic kids or are the manufacturers simply taking more care to protect themselves from liability?I think it's a combination of both things. This is a
very hot topic in the food industry.

The reality is that
no labeling schema is likely to serve the entire spectrum of allergic persons.
The problem, however, is that the center of the allergic distribution requires a fairly substantial triggering dose of the allergen-- in the case of peanut, it's astonishingly high, from personal reports (which come from research study participants in Chicago and at Duke and Sinai, so I trust that these are probably accurate reflections of study participants)-- as much as 4-5 peanuts. ON AVERAGE.
Okay-- so for those people, any kind of warning labels re: shared facilities are
probably overkill, because the liklihood of ever consuming enough of the allergen in a
contaminated (as opposed to mislabeled or adulterated) product to provoke a reaction is pretty low.
Okay, well, that would be one thing-- but there is a secondary troubling thing to consider: those with the lowest triggering doses (and we're talking VERY low, here-- perhaps 10's of
micrograms)
are prone to the most severe reactions. It's not a smooth dose-dependence curve, either-- that is, triggering a systemic reaction in someone with a higher threshold requires more, sure-- but they are also less likely to suffer cardiac or pulmonary consequences during that reaction, too. There are additional problems in that IRB approvals for threshold studies almost
always exclude those who have had previous life-threatening reactions to small doses. So they systematically skew to the center anyway. What data is there is very scary in terms of what it means for that outermost 2-3%, though.
So the real issue is the conundrum posed by that set of findings (all research-backed, as noted):
IF labeling is scrupulous enough to make labels reflect the level of safety that the 2-3% (who are most likely to suffer a fatal reaction, see), then by definition, it is
also going to be overly restrictive for the other 98% of the distribution.
The people worst off are those in the upper quartile-- because it's clear that they can get away with "more" risk than that uppermost 2-3%, but they aren't so tolerant that they can simply IGNORE the warnings, either.
About 5% of products with warnings (though I think this was about 2010) DID contain measurable amounts of protein, by the way.
I realize that doesn't help. I'm sorry.
What I'd probably do personally is model
calling manufacturers that use the labeling to find out what it means in the instance of anything in particular-- what form is the allergen in? What measures are taken to limit contamination, if any?That way you have information to work with.
