Every time you pick up a food package, you’re making a life-or-death decision if you or someone in your family has a food allergy. What looks like a simple ingredient list can hide dangers that even careful shoppers miss. In 2025, the FDA updated its guidance on food allergen labeling-changes that finally force manufacturers to be specific about what’s really in your food. But here’s the problem: not everyone knows what those changes mean, and some of them actually create new risks.
What’s Changed on Food Labels in 2026?
The big shift? Milk and eggs are no longer just "milk" and "egg." If your child is allergic to cow’s milk but can tolerate goat’s milk, you used to have to call the company and ask. Now, the label must say "goat milk" or "duck egg" right on the package. This isn’t a small detail-it’s a safety upgrade for millions. About 4.5 million Americans are allergic to cow’s milk, and 2 million have egg allergies. Many of them react only to one type of animal milk or egg. Before this rule, they were flying blind.
Tree nuts got a major update too. Coconut is no longer considered a tree nut under federal labeling rules. That’s good news for people with peanut or almond allergies who’ve been avoiding coconut for years, even though it’s botanically a fruit. The FDA removed it because studies showed coconut allergies are rare-only about 0.04% of the population-and unnecessary avoidance was causing stress and nutritional gaps. But don’t assume all tree nuts are safe. Almonds, cashews, walnuts, and pistachios still must be clearly labeled.
Shellfish labeling got tighter too. Only crustacean shellfish-shrimp, crab, and lobster-are now required to be named as allergens. Mollusks like oysters, clams, mussels, and scallops? They’re not covered. That’s a problem. Around 1.5 million Americans are allergic to mollusks, and many don’t realize they’re different from shrimp. A product labeled "may contain shellfish" could still contain oysters without warning. That’s a hidden danger.
"Free-From" Claims Are Now Strictly Regulated
You’ve probably seen products labeled "milk-free," "peanut-free," or "gluten-free." Now, if a product says "free-from," it must be truly free. No more mixing "milk-free" with "may contain milk" on the same package. That used to confuse people. If you saw "milk-free," you assumed safety. But then you read "may contain milk" and thought, "Wait-is it safe or not?" The FDA shut that down. A product can’t claim to be free of an allergen and then warn you it might have it. That’s misleading. Manufacturers now have to prove their products don’t have even trace amounts from cross-contact if they want to use "free-from." That means stricter cleaning, separate production lines, and better testing.
Hidden Allergens Are Still a Big Problem
Even with better labeling, hidden allergens sneak in. Soy sauce might contain wheat. Natural flavors can hide milk derivatives. Lecithin? It’s often from soy or egg. The FDA doesn’t require every hidden source to be spelled out-only the top nine allergens. That’s why you can’t rely on labels alone. You still need to read the full ingredient list, not just the "Contains" box. And you need to know what those ingredients really mean.
For example, casein is a milk protein. If you’re allergic to milk, casein is dangerous-even if the label says "dairy-free." Some brands use "non-dairy" to mean "no butter or cream," but casein is still there. The same goes for whey, lactoglobulin, or lactose. All are milk. If you’re allergic, you need to know the synonyms.
Another hidden risk: shared equipment. A cereal made in a facility that also processes peanuts might not list peanuts as an ingredient-but it could still have traces. The FDA says advisory statements like "may contain peanuts" are voluntary. That means some companies use them, some don’t. And if they do, they’re not required to say how much risk there is. "May contain" doesn’t mean "a little bit." It could mean enough to trigger a reaction.
Why Sesame Changed Everything
Sesame became the ninth major allergen in 2023 under the FASTER Act. Before that, it was hidden in everything: hummus, bagels, salad dressings, even some cosmetics. Now, it must be labeled clearly. But many people still don’t know how common sesame is. It’s in tahini, breading, spice blends, and snack bars. One study found that 1 in 50 children in the U.S. has a sesame allergy-higher than peanut allergies in some age groups. The change saved lives. But it also exposed how many products were hiding allergens for years.
Who’s Still at Risk?
The FDA’s new rules help, but they’re not perfect. People with allergies to mollusks, mustard, celery, or lupin aren’t protected. These are common allergens in Europe but not regulated in the U.S. If you’re traveling or buying imported food, you could be exposed. Also, alcohol labels aren’t covered by FDA rules. Wine, beer, and spirits might contain egg whites or milk proteins used in processing-but you won’t see it on the bottle. The Alcohol and Tobacco Tax and Trade Bureau doesn’t require allergen labeling.
Small food makers are struggling. A local bakery might not have the budget to retool labels, test every batch, or retrain staff. The FDA guidance is non-binding. That means compliance is optional. Some companies will follow it. Others won’t. That creates a patchwork of safety. If you buy from a small producer, you can’t assume their label is up to date.
What You Should Do Right Now
- Read the full ingredient list every time-even if you’ve bought the product before. Recipes change.
- Learn the hidden names for allergens: casein, whey, lactoglobulin (milk); albumin, ovalbumin (egg); soy protein isolate, textured vegetable protein (soy).
- Don’t trust "natural flavors" or "spices"-they can hide allergens. Contact the company if you’re unsure.
- Ask about cross-contact when eating out. Even if a dish doesn’t contain nuts, the fryer might have cooked them.
- Use apps like Fig or SpoonfulOfFlex to scan barcodes and get real-time allergen alerts.
- Teach your kids to ask, "What’s in this?" before eating anything new.
What’s Coming Next?
The FDA is already studying other allergens-like mustard, celery, and sulfites-to see if they should be added to the list. By 2027, experts predict most major U.S. food brands will follow the new labeling rules voluntarily. Consumer pressure is driving change. But enforcement is weak. The FDA inspects only about 10% of food facilities each year. That means a lot of unsafe products slip through.
For now, your best defense is knowledge. Labels are getting better, but they’re not foolproof. Stay alert. Ask questions. And never assume safety just because a product looks harmless.
Is coconut still considered a tree nut on food labels?
No, coconut is no longer classified as a tree nut under U.S. food labeling rules as of 2025. The FDA removed it because allergies to coconut are rare and many people with tree nut allergies can safely eat coconut. Labels now list coconut separately, so if you have a tree nut allergy, you can tell whether coconut is included.
Can a product say "milk-free" and also say "may contain milk"?
No, that’s no longer allowed. As of 2025, the FDA prohibits using both "free-from" claims and advisory statements like "may contain" for the same allergen on the same product. If a label says "milk-free," the product must genuinely have no milk or milk derivatives, even in trace amounts from cross-contact.
Are mollusks like oysters and clams labeled as allergens?
No, mollusks are not required to be labeled as allergens in the U.S. Only crustacean shellfish-shrimp, crab, and lobster-are covered under federal labeling rules. People with allergies to oysters, clams, mussels, or scallops are at risk because those ingredients can be in foods without any warning on the label.
Do alcohol beverages have to list allergens?
No, alcohol beverages regulated by the Alcohol and Tobacco Tax and Trade Bureau (TTB) are not required to list allergens. Ingredients like egg whites or milk proteins used in processing wine or beer don’t need to appear on the label. Always check with the manufacturer if you have allergies.
How can I tell if a food has hidden allergens?
Look for vague terms like "natural flavors," "spices," "stabilizers," or "emulsifiers." These can hide allergens like milk, soy, or egg. Check for synonyms like casein (milk), albumin (egg), or soy protein isolate (soy). When in doubt, contact the manufacturer directly or use an allergen-scanning app.
