Overview
About Celery seed
Celery seed is the one spice on this list where the allergy label matters more than the chemistry grades.
Celery is a declarable allergen in the EU and UK, one of the fourteen that must be named on a label no matter how small the amount, and celery seed is the concentrated form of it: the seed of wild celery (smallage), not the salad stalk. Reactions to celery are well documented and range from oral itching to full anaphylaxis, including exercise-dependent cases where the food alone is tolerated. On the food-chemistry side the seed reads clean, with histamine, salicylate, oxalate, nickel, glutamate and every FODMAP subgroup graded A, and none of the stalk's polyol problem carries over at pinch quantities. So if you tolerate celery, the seed is an easy seasoning. If you do not, the seed is the version most likely to hide from you, because it mostly reaches your plate as celery salt.

What trips people up
- Celery is one of the fourteen allergens that must be declared on EU and UK labels, and that includes celery seed, celery salt and celery extract. It is not on the United States major allergen list, so a US label can legally bury it inside "spices" or "natural flavor"
- Celery salt is simply ground celery seed mixed with salt, which is how celery hides in Old Bay, in the rim of a Bloody Mary, in tomato juice, hot dog and coleslaw seasonings, potato salad, brines and dry rubs. This is the single most common way people with celery allergy get an unexpected dose
- Gram for gram the seed carries far more celery protein than a stalk does, and cooking is not a reliable safeguard: the birch-related celery allergen breaks down with heat but others in celery do not, so cooked celery has still caused reactions
- Celery sits at the centre of the celery-mugwort-spice cluster, so mugwort and birch pollen allergy raises the odds of reacting to celery and to its Apiaceae relatives like carrot, fennel and coriander
- The food-chemistry grades themselves are quiet: histamine A, liberator A, salicylate A, oxalate A, nickel A and glutamate A, with the overall FODMAP figure unrated rather than high

FAQ
Common questions about Celery seed
Is celery seed an allergen?
Yes. Celery is one of the fourteen allergens that European and UK food law requires to be declared, and celery seed counts because it comes from the same plant, Apium graveolens. Reported reactions run from oral allergy symptoms to anaphylaxis, and there is a recognised food-dependent exercise-induced form where the reaction only appears if exercise follows the meal. The United States takes a different approach: celery is not one of its major allergens, so it can appear on a US label only as part of a generic spice blend.
Is celery seed the same as celery?
Botanically yes, culinarily no. Celery seed comes from wild celery or smallage, a bitter uncultivated form of the same species that was never bred for fat crunchy stalks. It tastes far more intense and slightly bitter, which is why it is used by the pinch. For allergy purposes treat it as celery. For trigger purposes it behaves quite differently from the stalk, since the stalk is graded high on polyols and overall FODMAPs while the seed is not.
Is celery seed low FODMAP?
Its individual FODMAP groups are all graded clean here (fructans, polyols, GOS and excess fructose all A), while the overall FODMAP figure is unrated rather than high, so we will not call it certified low. What we can say clearly is that the stalk's problem does not automatically transfer: celery stalk grades high on polyols, and you eat a stalk by the cupful and a seed by the quarter teaspoon.
Does celery salt count as celery on a label?
Yes. Celery salt is ground celery seed blended with salt, so in the EU and UK it triggers the same allergen declaration. If you are avoiding celery, celery salt is the item to hunt for in seasoning blends, seafood boils, cocktail rims and packaged salads, and it is worth checking any product that lists a proprietary seasoning without breaking it down.
