Panic sets in—could this be a food allergy? You rush to check the package, but the ingredient list is long, and the print is tiny. How can you be sure what triggered her reaction?

In this comprehensive guide, we’ll explore how to identify allergens in food, understand global labeling laws, and use smart technology like Food Scan Genius to make safer choices.
Why Is Allergen Awareness Important?
- Food allergies affect up to 10% of children and 4% of adults globally[FDA].
- Undeclared allergens are among the top causes of food recalls in the US and EU[EFSA].
- Symptoms can range from mild hives to life-threatening anaphylaxis.
For those with allergies or food sensitivities, ingredient transparency is a matter of life and health.
How To Know If Food Contains Allergens? (Quick Answer)
- Read the ingredient list for common allergens.
- Look for “Contains” statements or allergen warnings.
- Check for precautionary labels like “May contain.”
- Use a food scanner app (like Food Scan Genius) to instantly check products.
- Contact the manufacturer if in doubt.

According to the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), the most common allergens include:
| US (FDA) | EU (EFSA) |

How Are Allergens Labeled on Food Packages?
US Allergen Labeling Laws (FDA)

- Precautionary statements like “May contain traces of peanuts” are voluntary.

EU Allergen Labeling Laws (EFSA)
- Manufacturers must emphasize 14 allergens in the ingredients list (e.g., bold, uppercase, or color).
- Allergen information must be available for non-packaged foods (restaurants, bakeries).
- Precautionary statements (“May contain”) are also voluntary but widely used.
How Can You Identify Hidden Allergens?
Some allergens hide under unfamiliar names or as part of complex ingredients. Here are tips for spotting them:
- Whey, casein, lactose = Milk
- Albumin, globulin = Egg
- Hydrolyzed vegetable protein = May contain soy or wheat
- Spices, “natural flavors” = May hide allergens (ask manufacturer)
Pro tip: Use a scanner app like Food Scan Genius to decode ingredient lists instantly.
Q&A: Common Questions About Food Allergens
Q: What’s the difference between “Contains” and “May Contain”?
A: “Contains” means the allergen is an intentional ingredient. “May contain” or “processed in a facility with” means there’s a risk of cross-contact, but the allergen is not an intended ingredient.
Q: Are allergen labeling laws the same worldwide?
A: No. The US (FDA) and EU (EFSA) have different lists of required allergens and labeling formats. For example, the EU mandates disclosure of celery and mustard, which are not required in the US.
Q: Can I trust “allergen-free” labels?
A: Not always. “Allergen-free” means the product is made without certain allergens, but cross-contact can still occur. Always check for precautionary statements and contact the manufacturer if you have severe allergies.
