What about allergies (nut or shellfish) in Morocco?

Travelling with a serious food allergy in Morocco is entirely possible, but I won't pretend it's effortless — it takes vigilance, because Moroccan cuisine genuinely loves nuts. Almonds in particular are everywhere: ground into pastries like the famous kaab el ghazal and pastilla, scattered over tagines, blended into sauces, and present in amlou (that delicious argan-almond-honey spread). Argan oil itself is a tree nut product. Sesame, peanuts, and pine nuts crop up too. So for a nut allergy especially, you have to assume nuts could be hiding in a dish until you've confirmed otherwise.

The most powerful tool by far is a translation card. Have your allergy written out clearly in both Arabic and French — 'I have a severe allergy to nuts/almonds/peanuts; even a trace can make me very ill; please ensure my food contains none' — and show it at every restaurant, stall, and riad kitchen. French is widely understood in hospitality and Arabic reaches everyone; a printed card removes the guesswork that a hurried verbal exchange across a language barrier leaves behind. I've seen these cards work where halting explanations failed completely.

Carry your own emergency medication and don't assume you can buy it locally. Bring at least two in-date EpiPens (or your prescribed auto-injectors), keep them in your carry-on and on your person, and make sure your travelling companions or guide know where they are and how to use them. Pack your antihistamines too. Anaphylaxis kit is not something to gamble on finding in a Moroccan pharmacy, particularly outside the cities — bring everything you might need from home.

Shellfish allergy is a little easier to navigate inland, since shellfish is mainly a coastal thing — Essaouira, Casablanca, the Atlantic ports — so you can be especially careful at seafood spots and relax a touch elsewhere, though always still check. Across the board, favour places that can tell you exactly what's in a dish, be wary of communal and street food where cross-contamination is likely, and when in doubt, don't. And please plan your allergy management with your own doctor before the trip — confirm your prescriptions, your action plan, and that your insurance covers an allergic emergency.
