How to avoid getting sick in morocco

Water
Whenever traveling to any other country, you will find the water chemistry is different than in your own. For many people, drinking it will cause horrible pain and diarrhea for several days up to a week. If you are only staying for a few weeks and want to avoid the water chemistry change over reaction, avoid drinking fresh water. You can buy bottled water and mineral water on every corner in Morocco as well as in the local grocery stores. You can also buy soda or fizzy water. It is best to stick to mineral water versus regular bottled water, because mineral water is less likely to be contaminated in the bottling process.

Drinking Moroccan tea or coffee is perfectly OK and will not make you sick, because the water has been boiled.

Homemade Food
In general food that is cooked through will not make you sick. But do not be surprised if you find it was mixed with bare hands. This CAN make you sick as bacteria on the hands gets transferred to food. There is no way to really avoid this other than to watch for it and avoid eating the foods mixed with bare hands.

Moroccans use a lot of oil and fat in their cooking. If you are sensitive to this, watch out for it. You can find your breakfast eggs dripping in oil unless you ask for them to not use as much.

Street Vendor Foods
Most people recommend avoiding foods sold by street vendors in Morocco. I have to disagree. As long as it is not soaking in oil (too much can make you sick), and clean, it should be fine. All kinds of cooking doughs sold on the streets are made with bare hands and lots of oil. Foods like sugar coated roasted almonds are perfectly OK to eat. You just need to be a bit pickier than in the US.
