My 5-year-old son is in a kindergarten class with a strict "dairy-free snack policy" due to a classmate's severe allergy.
I bought a 70% dark chocolate bar. The ingredients list has zero dairy (cocoa mass, sugar, cocoa butter). But below it says: "May contain traces of milk."
My son has no allergies himself.
Can I pack this for snack tomorrow, or does the dairy-free classroom rule prohibit "may contain" labels as well? What should I do tonight?
Answer
I'll check the family profile and pull a source line on "may contain" labels before I answer.
Don't pack this bar for tomorrow yet — send one message to the class teacher (or the school office) tonight asking the one line only they can answer: **does the dairy-free snack policy cover precautionary "may contain milk" labels, or only listed ingredients?** Until that line is back, leave this bar out of the snack.
## Tonight
- **Keep the wrapper** — brand, the full ingredients list, and the lot number. The teacher may want to see the exact bar tomorrow morning, and if there is any doubt later it is the lot that gets checked.
- **Message the teacher** for that one line only they can answer (ingredients-only, or also "may contain" labels). One short note is enough — the school's dairy-free policy wording is what decides, not anything we can read off the bar.
## Why the bar alone can't decide it
"May contain traces of milk" is a **voluntary** warning from the maker. It is not on the ingredients list, and it is not a verdict that the bar is safe or unsafe — it just means the maker cannot rule out that the production line touches milk. For your son at home it doesn't matter (he has no milk allergy), but for the classmate with the severe dairy allergy, whether a trace warning matters is exactly the kind of detail that sits in **that child's signed allergist plan** — which is why the classroom rule exists in the first place, and why only the school can tell you where the line is.
Two source lines worth keeping in mind, in case the school asks why a "may contain" bar can't just go in:
> "The raw ingredients may be contaminated with peanuts, however the food does not have peanuts as an ingredient." — ASCIA, *Dietary avoidance for food allergy* [allergy.org.au](https://allergy.org.au/patients/food-allergy/ascia-dietary-avoidance-for-food-allergy/peanut)
> "The absence of an advisory label does not mean that a product is safe." — FAE, *How to read a food label* [foodallergy.org](https://www.foodallergy.org/resources/how-read-food-label)
So "may contain" can mean real cross-contact even when the ingredients look clean, and a bar with no warning at all is not automatically fine either — which is again the school's call, not the wrapper's.
## If you don't hear back tonight
Default to leaving this bar out and pick something with **no** "may contain milk" line at all for tomorrow — plain fruit, a clearly dairy-free biscuit or a dark chocolate that is labelled dairy-free and made on a dairy-free line. Once the teacher replies, you'll know whether this 70% bar comes back into the snack rotation or stays home.
If you want, draft the message to the teacher in your own words and I'll tighten it before you send.
