If you're in doubt about what to eat or drink, the Centres for Disease Control in Atlanta, Georgia, recommends a "Boil it, cook it or forget it" approach.
Here are some tips that will help keep you healthy:
- Only drink water that has been boiled or treated with chlorine or iodine. Tea and coffee (made with boiled water) are a safe bet, as are carbonated or bottled drinks. Don't make the mistake of adding ice to your drinks as, chances are, it will have been made with untreated water;
- Be sure to eat food that's thoroughly cooked and still hot;
- Opt for fruit that can be peeled. Make sure you wash any fruit you eat in treated water;
- Steer clear of raw or undercooked seafood and shellfish;
- Make sure all vegetables are cooked and give salads a wide berth;
- Although part of the fun of visiting a new country is eating the local cuisine, if there's a risk of cholera, avoid eating from street vendors who may not have access to clean water.
