Sesame seeds are widely used in Middle Eastern, Asian, and Mediterranean cuisines
Sesame oil retains proteins and is NOT safe for sesame-allergic individuals
Check breads, breadsticks, crackers, burger buns, and Asian sauces

Cross-Reactivity

Rye — trace cross-reactivity possible

Sesame in Middle Eastern cuisine

Sesame is a cornerstone ingredient in the Middle East — present in tahini, hummus, falafel coatings, za'atar, and many breads and pastries. Patients living in or travelling to Gulf countries should be particularly vigilant.

Even 'plain' dishes in restaurants can contain sesame from shared cooking surfaces or seasoning mixes.
