Hygiene

Practicalities Health Hygiene Dos and Donts 

Though not necessarily dangerous, new places mean new bugs and small children's immune systems will not yet be in a position to fend off all of these very comfortably.

Do
Make sure hands are always washed before eating and as much as possible the rest of the time. Children can pick up worms from the soil in certain tropical zones for example. Carrying a clean, wet cloth for dirty fingers is one suggestion although use of an antiseptic would be more effective if you have serious concerns.
Do
For a baby sterilise water and utensils and follow all rules on hygiene scrupulously, This is particularly so if not breastfed and if older than the three months, before which time the mother's immunity is held to offer protection.
Do
Stick as far as possible to dishes the locals eat (this doesn't include tourist buffet versions) as the local cooks will understand how they need to be handled to avoid health problems.

Don't
Eat food which has been on a buffet or other display in warm weather, especially if there are flies and tepid dishes like casseroles which may have been kept warm for some time. (This can be an argument against taking a half board package holiday, or even more an all-inclusive, which often include buffet meals.)
Don't
Eat shellfish unless you are sure that it is fresh and from clean water.
Don't
Eat salads, unpeeled fruit or other raw food unless you are certain it has been washed in clean water. You could simply peel them yourself after washing your hands carefully, or if self-catering wash in treated water. In all events think about avoiding large leaf items like lettuce and spinach which because of their surface area have a greater than average potential for carrying infection.
Don't
Take ice in drinks unless you are sure it is made with clean water and handled hygienically. (Hotels offer no guarantee of this.)
Don't
Eat ice cream unless you are sure it has been properly stored at low temperatures and if really worried stick to big name brands. In developing countries avoid other dairy products including custards and mayonnaise as well, as you can't be sure of hygiene standards.
Don't
Eat meat if you are in a country where you fear it might have been badly stored.
Don't
Swim in water you think is polluted.
Don't
Brush teeth using tap water unless you are happy it is safe.
Don't
Allow children to drink bath water.
Don't
Allow children to touch anything in public loos unless you give them the go-ahead. In some cases even the soap is best avoided.
