How do you avoid stomach problems in Morocco?

To avoid stomach problems in Morocco, drink only bottled or filtered water, eat freshly cooked hot food from busy places, and ease your gut in gradually rather than diving into everything at once. Most travellers’ upsets come from unfamiliar microbes and tap water rather than genuinely "bad" food, so a few simple habits prevent the majority of trouble.

Skip tap water and ice in cheap places, be cautious with raw salads and cut fruit washed in tap water, peel fruit yourself, and choose stalls with high turnover where food is cooked to order. Carry hand sanitiser and wash before eating with your hands.

Build up to street food over a day or two, and pack rehydration salts and an anti-diarrhoeal just in case. If something does hit, rest, rehydrate, and see a pharmacy — Moroccan pharmacists are excellent and helpful.
