Milk allergen labeling on US food packs
If milk is an ingredient in an FDA-packaged food, FALCPA requires the word milk — whey, casein, butter, cream, lactose-free milk and ghee included when they come from milk. A “dairy-free” front claim does not replace that declaration when milk is still in the formula.

The short answer
If milk is an ingredient in an FDA-packaged food, FALCPA requires the word milk — whey, casein, butter, cream, lactose-free milk and ghee included when they come from milk. A “dairy-free” front claim does not replace that declaration when milk is still in the formula.
Where this shows up in a real kitchen
US bakeries hide milk in butter, buttermilk biscuits, cream cheese frostings and milk chocolate chips. Lactose-free milk is still milk. Goat and sheep milk are milk. Coconut “milk” is not cow’s milk — it is coconut, which FDA treats as a tree nut for allergen labeling.
The US rule
Milk is a major food allergen. Declare it by the common name milk in the ingredients list or Contains statement. FDA’s allergen page lists obvious and less obvious milk derivatives. Nutrition Facts “includes Xg added sugars” is unrelated to whether milk is declared.
How to apply it
Scan specs for whey, casein, sodium caseinate, butter, ghee, lactose, milkfat, recaldent. Put milk in parentheses after the derivative or in Contains. If you truly removed milk, remove it from Contains the same day and watch shared mixers.
- Highlight every milk derivative on the spec, including lactose-free lines.
- Declare milk in the list or Contains.
- Drop milk from Contains when the formula is truly free of it.
- Separate coconut milk (tree nut / coconut) from cow’s milk in staff training.
Worked example
A “dairy-free” brownie that still uses butter in the pan release: the marketing claim is false and milk must be declared. A genuinely oat-milk brownie lists oat milk, not milk, and does not put milk in Contains. Shared pans that always see butter may justify a voluntary advisory, not a fake Contains: milk.
Checks that belong on this pack
| Check | Why it matters |
|---|---|
| Butter and ghee count as milk | Fat from milk is still milk under FALCPA. |
| Lactose-free milk still says milk | Lactose is a sugar; the allergen is the milk source. |
| Dark chocolate specs are read | Many “dark” chips still contain milkfat. |
| Contains does not say dairy | The legal word is milk. |
Treating lactose-free as milk-free
People with milk allergy are not all lactose intolerant. FALCPA cares about milk protein sources, not lactose content.
What LabelClear can and cannot print
When you paste butter or whey into the generator, confirm milk is marked. That matches FALCPA’s common-name rule.
Questions
Is clarified butter milk?
What about enzymes from milk?
Does “may contain milk” replace Contains: milk?
