Many holidays for young travellers will include plenty of eating out and drinking, but it will be recommended to make sure that you are not consuming anything that could be potentially harmful. Meat and dairy products will pose the biggest threat, and it is also not possible to bring in any of these items into the UK if they have been purchased from outside the EU.
Countries in hotter climates can often have a lower level of hygiene in comparison to the UK, and disease such as cholera and hepatitis can be spread by contaminated food. If you are dining out, make sure the location you choose is clean. Any meat that has been exposed to the elements where flies are near poses a high risk of carrying disease. Fruit and vegetable should also be avoided if they are uncooked, unless you are able to peel them yourself. Ice cream is another food item that can carry disease if it is not cooled properly, and it is not recommended to buy ice cream from mobile sellers.
When it comes to drinking and alcohol, as well as excessive binge drinking there are plenty of other ways you can run into health problems. Putting ice in your drinks should be avoided, unless you know that it has come from chlorinated water. Bottled water is also worth purchasing if you are in any way in doubt over the local water supply, and purifiers will prove to be a lot more reliable than sterilisation tablets.
