When travelling abroad, you may be exposed to a number of different things that can cause illness. Unpleasant and potentially dangerous infections can be caught by eating or drinking contaminated food and water. Because of this, you should take precautions with food and water in places where it is hard to maintain a good level of hygiene and sanitation.
There are some general rules that you should follow whenever possible while travelling. These include:
You should avoid eating street food, unless you can be sure that it has been cooked thoroughly and it is served hot, on clean plates.
Some foods are more likely than others to carry bacteria, viruses or parasites that can make you ill. Foods to be careful with include:
Whenever possible, you should buy products from well-established shops where the food is more likely to be of good quality.
When you are travelling, you should only drink water if you are sure it is clean. Boiled water, sealed bottled water, hot tea and coffee. Beer and wine are normally safe to drink, in moderation.
You should never drink unsafe water without boiling it or using a reliable filter to clean it first. This is also the case for using water to brush your teeth and make ice cubes. You should also boil milk before you drink it, unless you can be sure that the milk is safe to drink and anything that can cause infection has been removed or killed.
Make sure you contact your GP or travel health practitioner in plenty of time before you travel to discuss the ways you can help to keep yourself healthy whilst away. You should try and contact them at least 4–6 weeks before your trip.
After your trip, you should contact your GP if you develop a fever or diarrhoea or notice any other unusual symptoms.
