Research, Review, Report: ReAction
Shop with caution, eat with confidence. The ReAction community has your back.
The problem
“May contain” means squat diddly.
Precautionary labeling — “may contain,” “shared facility,” “shared machinery” — is entirely voluntary in the US. No law requires it, governs its wording, or checks that it's accurate. Products carrying a “may contain” warning often contain no detectable allergen at all — and just as often products with no warning do contain detectable allergens.

Laws requiring “may contain” labels to be accurate, tested, or even used at all.

Times the US allergen label list has been updated since 2004.
9/14
Allergens the US requires disclosed, versus what the EU already mandates.
The FDA is exploring a fix — a standardized system tied to actual allergen thresholds. It's still gathering public comment. No proposed rule, no timeline.
What it does
Labels tell you what's declared. ReAction tells you what's happened.
Scan and know
Point your camera at a label. We show you what the manufacturer has declared — and flag if others have reported adverse reactions.
Real people. real reports
May contain nuts, or definitely cross contaminated? Every entry comes from someone with a profile like yours. Your report helps others.
Restaurant reviews that matter
The pasta is only 5 stars if you can safely eat it. Most ratings don't consider your allergy. Ours do — sourced from people who've actually eaten there and who understand.
An incident report that writes itself
Real change comes from real awareness. Post to ReAction and we will guide you through the FDA and manufacturer reporting process.
Nothing reported yet on your allergen?
That's not the same as nothing to report.
