Why Scanning Food Labels for Allergens Matters

Whether you have a diagnosed food allergy, a sensitivity, or simply want to make informed choices about what you eat, scanning food labels for allergens is a vital skill. According to the FDA, over 32 million Americans have food allergies, and the prevalence is rising globally¹. Recent news from The New York Times highlights the growing concern over accurate allergen labeling and the risks of hidden ingredients.

But scanning food labels isn’t just for those with allergies. It’s essential for:

• People with food intolerances or sensitivities (e.g., lactose intolerance, celiac disease)
• Parents shopping for children with dietary restrictions
• Anyone managing chronic conditions influenced by diet
• Individuals pursuing plant-based, vegan, or kosher diets

Understanding how to scan food labels for allergens empowers you to make safer, healthier choices—whether at the supermarket, a restaurant, or online.

What Are Allergens and Why Are They Labeled?

Food allergens are substances in food that can trigger immune reactions in sensitive individuals. The most common allergens, known as the “Big 9” in the U.S., include:

Labeling laws, such as the Food Allergen Labeling and Consumer Protection Act (FALCPA), require manufacturers to clearly declare these allergens on packaging. The European Food Safety Authority (EFSA) enforces similar regulations in the EU².

How To Scan Food Labels for Allergens: Step-by-Step

Scanning food labels effectively means more than just glancing at the packaging. Here’s an expert, step-by-step guide:

1. Locate the ingredient list.
   Most packaged foods have an ingredients panel on the back or side. Look for the section labeled “Ingredients.”
2. Identify allergen statements.
   Manufacturers often use bold text or a separate “Contains:” line to highlight allergens. For example: Contains: Milk, Wheat, Soy.
3. Check for precautionary statements.
   Look for warnings like “May contain traces of peanuts” or “Produced in a facility that processes tree nuts.” These indicate potential cross-contamination.
4. Scan for hidden sources.
   Some allergens are disguised under technical names. For example, casein and whey are milk derivatives; albumin is an egg protein.
   • Milk: Casein, whey, lactoglobulin
   • Eggs: Albumin, ovalbumin
   • Wheat: Gluten, semolina, farina
5. Use a digital scanner or app.
   Apps like Food Scan Genius let you scan barcodes or ingredient lists with your phone, instantly flagging allergens and dietary concerns.
6. Double-check imported products.
   International foods may use different labeling standards or languages. Always verify unfamiliar ingredients.

By following these steps, you reduce your risk of accidental exposure and make informed choices every time you shop.

Common Challenges in Scanning Food Labels

Despite regulations, scanning food labels for allergens can be tricky. Here are some common obstacles:

• Small print and confusing layouts make it hard to spot allergens quickly.
• Ingredient changes occur without notice; brands may reformulate products.
• Cross-contamination risks are often buried in fine print.
• Technical jargon (e.g., “hydrolyzed vegetable protein”) may mask allergen sources.
• Imported goods may not follow local labeling laws.

Recent headlines from CNN report on recalls due to mislabeling, underscoring the importance of vigilance.
