The One Chip isn’t dangerous due to allergens per se, but compounds which can have a strong effect on people’s internal biology the same way a pharmaceutical would especially in the concentrations they’re using to get the super spicy outcome. Regardless of whether the kid had a preexisting condition if the chip’s affect on his body caused changes which contributed to his death then there could be others out there who would have similar complications and as the product continues to gain popularity there is increasing liklihood of such things happening.
These things aren’t tested for safety in any way. Hell, a 14 year old was able to get ahold of the product with presumably no issues.
Paqui is being safe by recalling the product, and hopefully we can get to the bottom of this before anyone else is hurt.
