People often tell themselves: "Oh, that's just a lawyer's trick to avoid a lawsuit. It's probably fine." But the science tells a different story. "Precautionary Allergen Labeling" (PAL) is based on the real manufacturing environment.
The Statistics
Studies testing products with "May Contain" warnings found that roughly 10% to 15% of them actually contained detectable amounts of the allergen. That means if you eat 10 such "risky" snacks, you are almost guaranteed to hit one that has cross-contamination.
Different Phrases, Same Danger
There is no legal regulation on how the risk is phrased. These all mean the same thing:
- "May contain traces of peanuts."
- "Processed on equipment that also processes peanuts."
- "Made in a facility that handles peanuts."
Incorrect. Since this labeling is voluntary in the US, a company can have cross-contamination and simply choose not to label it, unless they make a specific "Free-From" claim.
Who should avoid it?
If you have an IgE-mediated anaphylactic allergy, you must avoid ALL "May Contain" products. The risk of reaction is too high. If you have a mild intolerance (like lactose intolerance where small traces don't bother you), you might tolerate them.
Make Informed Decisions
"May Contain" warnings indicate real cross-contamination risk. AllergenFinder identifies these warnings on labels along with any direct ingredients you need to avoid. You decide your own approach to precautionary labels based on your specific situation and medical guidance, but the app ensures you see them clearly so you can make informed choices.
