Current European regulations require the labeling of all foods containing sesame seeds or seeds and sesame-based products.

Sesame seed allergy can cause very serious allergic reactions (anaphylaxis) in both adults and children.

Sesame has also been described as an allergen capable of inducing asthmatic reactions, especially by occupational asthma.

A patient allergic to sesame seed is likely to be also to other nuts (nuts, peanuts and cashews) and legumes (lentils and soybeans).
