Expect to learn in the chapters that follow how to eat armadillo without contracting leprosy.
Well-cooked, piping hot meals are safe, but food that is lukewarm or has been cooked, allowed to go cold, and then is handled by someone is risky.
There are innumerable myths about what causes bad stomachs in travelers, but it is nearly always contaminated food, or occasionally - just occasionally - dirty water.
Salads are often grown in highly contaminated ground (people without toilets often relieve themselves in vegetable gardens), and low-growing fruits, especially strawberries, can easily become contaminated by human feces. The most hazardous raw foods are those that can trap filth in crevices and are difficult to clean - lettuce is among the worst. Conversely smooth skinned items can be cleaned quite well, so carefully washed tomatoes and items that can be peeled like carrots or radishes are fairly safe.
The myth of locals being immune is ill-informed travelers' folklore, and the distressingly common idea that eating bad food will immunize you is responsible for a lot of unnecessary illness in travelers, as well as exposing them to dangerous filth-to-mouth infections like thyphoid.
In the Middle East and South Asia, some melon sellers puncture the fruits and soak them in roadside drains to make them weigh heavy before sale. This is a probable explanation of why, in the days of the British Raj, melons were blamed for Indian cholera outbreaks.
Choose freshly cooked, piping hot food rather than reheated food or food kept lukewarm on a hotel buffet. Sizzling hot street food is likely to be safer than just warm food, even if produced by an international hotel. In international hotels order à la carte foods if you can.
Pork and dog are the riskiest kinds of meat. Pigs and dogs are often the local rubbish disposal consultants where environmental hygiene is poor.
In most developing countries, fresh milk - even milk that says it is pasteurised - should be boiled before drinking.
Yogurt is usually safe because the milk is boiled before fermentation and the final product is slightly acidic and thus less favorable for the survival of noxious bacteria.
Sorbet tends to be acidic and, since acids are unfavorable ot bacteria, this is a fairly safe food. Ice cream is often risky in developing countries since power cuts make it difficult to store safely, and it is microbe paradise. Ice, too, is often made with dirty water or handled with dirty hands. Sometimes it is delivered in huge blocks that are dumped onto the ground outside the drinks stall or hotel.
I'm often surprised at the women travelers who don't know about panty liners. Many of us have used them for years, and find we only need two extra pairs of briefs for even a long trek as they keep clean for days. Bring enough for one per day, plus extras for accidents, or for added protection during a bout of diarrhea. They come in various lengths, and the most convenient are individually wrapped, so a spare can be slipped into a pocket. Pack them in a small zip-lock bag. Extras will always be gratefully received by a woman who hasn't yet experienced the comfort and convenience.
Studies in several Asian countries suggest that bottled mineral water produced locally may not be entirely safe. Most of it is not even "mineral water" but treated (or untreated) tap water. Yet there has been a boom in "mineral water" production so that it is available in a surprising number of quite remote destination now. The quality is patchy, but if I need water in a city in the developing world, I drink bottled water. It is usually safe enough. Other kinds of bottled drinks, the colas and other carbonated drinks, should be safe because the contents are somewhat acidic which is unfavorable for microbes, and boxed drinks will also be safe. Beware of "homemade" drinks that have involved a lot of handling during concoction.
If you need really safe water - you may be traveling with a young baby or your own health dictates that you must take special care - the safest means of treating water is to boil it. Water that has been brought to a good rolling boil is safe, and even water heated above 60C is unlikely to harbor any nasty microbes.
Chemical "sterilization" takes time (thirty minutes), gives water a taste, and does not kill all microbes. But for most purposes the water will be rendered safe enough. Safest of the chemical options is iodine, and chlorine is the next most efficient means. Adding vitamin C reduces the unpleasant taste from iodine, but this must not be added until the purifying thirty minutes has been completed.
When staying in a more down-market place ask for a glass of boiling water.
If you are offered a drink - or food - which you think may be contaminated, take as little as possible; the less you consume, the less you risk stomach trouble.
Excessive use can cause enlargement of the thyroid gland in the neck, so long-term users should not add iodine to all their drinks. It is usually possible to take a range of drinks from various safe sources and a great deal should be in the form of boiled water.
Travelers in developing countries can be lulled into a false sense of security by assuming that bottled water is safe water. Tests and visits to bottling plants in Nepal showed that while the majority of samples were free of fecal contamination, some rogue companies were merely bottling inadequately treated tap water. Quality control is a major issue - even leading companies lack on-site lab facilities to test for many impurities. A number rely on one-off tests in Europe at the start of production to accredit their brands. Nepal, like many countries with limited resources, has very few regulations in place to protect the quality of bottled water. This problem is not restricted to the developing world. In the USA, the Natural Resources Defense Council (1999) tested 1,000 samples of 103 U.S. brands and found that at least one-third had levels of bacteria and chemicals that exceeded the standards regulating the bottled water industry.
The liver of dogs, bears, and other carnivores is so loaded with vitamin A as to be toxic. Don't eat it.
The easiest way of taking such a sugar and salt solution is to open a packet of Oral Rehydration Salts (ORS), dissolve it in clean water, and then drink a couple of large glasses after each time you open your bowels. [...] It is important to get the volume right; improperly made up solution can do more harm than good. If in doubt, overdilute.
Normally you obtain a lot of fluid from your food, about three liters a day.
Allowing yourself to get dehydrated in hot climates will put you at risk of kidney stones and bladder infections.
He misunderstood that together salt and sugar (whether in the form of ORS or salt added to cola) are a vehicle for fluid absorption, not a one-off treatment.
These kinds of cramps are common in diarrheal disease, but eating small quantities of bland foods can reduce them. Pure carbohydrates are best (boiled potatoes, rice, couscous, or plain crackers), and these also assist absorption of fluids if you drink plenty of water with them.
The physiological phenomenon called the gastro-colic reflex is something that travelers should understand. When any hot or very cold food or drink is swallowed, there is a reflex tendency for the bowels to open. Under normal circumstances this happens perhaps when breakfast stimulates your daily evacuation.
If your intestines are ailing, then, avoid very hot drinks or foods or very cold or iced drinks. Aim to take any drinks at room temperature and allow food or hot drinks to cool before consumption.
I had no other choice but to shit into a carrier bag and throw it out the window. It was no fun for me or my husband lying beside me. Have a carrier bag and toilet paper with you at all times!
Explosive diarrhea that comes on suddenly, you feel awful, often there is fever and, sometimes, visible blood in the stool, suggests bacterial or bacillary dysentery, usually due to Shigella. It definitely will ruin your day and is best treated with oral rehydration therapy and antibiotics. If you can, go to a doctor and get a stool checked in a laboratory. If none is available, consider taking a threeday course of one of the following antibiotics: ciprofloxacin, norfloxacin, or nalidixic acid.
It is dangerous to treat dysentery (bloody diarrhea or severe diarrhea with fever) with "blocking" paralytic medicines such as Immodium or Lomotil. They can cause intestinal perforation.
The typhoid risk is highest in those visiting tropical Latin America or the Indian subcontinent. Travelers to other regions too might choose typhoid immunization, but this decision is dependent upon how "rough" you are traveling. It is worth noting that the injectable vaccines do not give any cover against paratyphoid fevers, however the new oral vaccine probably offers around 50 percent protection. In addition immunity, although only partial, appears to last longer.
If you need to get your underwear to dry quickly, roll it in a hotel towel.
A large, tough plastic bag is useful for soaking dirthy clothes overnight so that they are then easy to wash. Cheap hotel sinks often have no plug, and improvised stoppers will not maintain a full sink all night.
Malaria mosquitoes love sweaty feet, so a shower before dusk will reduce the bite rate.
Having a good wash can demand some subtlety, but cleaning wonders can be achieved, in the privacy of a very small tent, by squatting over a small dish of water and using a disposable cloth, soap, and preferably a close friend to scour your back. Start before sunset (with its attendant frost or mosquitoes) and begin at the savory end of your person, the lips. Then systematically work your way down. If you wish to use the cloth ever again, keep green ones for the upper part of your lovely body, and blue for bottoms. Finally hang the cloths out to dry, which they do even in a heavy frost at night, and once dry (usually about an hour after dawn), you can pack them into separate polyethylene bags. When they begin to get a bit fruity, just burn them and use new ones.
If you want to bathe outdoors and there are lots of people about, it is possible to bathe modestly by putting on a sarong or lungi. This is a tube of cotton cloth that is wide enough to cover all essentials so that you can bathe comprehensively but modestly under a village waterspout in full view. For women, a long wraparound skirt can be used in the same way. Such garments will dry quickly in the midday sun along with your freshly washed underwear.
If your bathing water comes from a source that may be contaminated with bilharzia, try to ensure that the water is taken from the lake in the early morning and stored snail-free, otherwise it should be filtered or have Dettol or Cresol added.
If you have been exposed to bilharzia parasites, arrange a screening blood test more than six weeks since your last contact with suspect water.
Bathing early in the morning carries a lesser risk for bilharzia than bathing in the last half of the day.
The species that occur in Africa and the Middle East (Schistosoma haematobium and S. mansoni) and America (Schistosoma mansoni) are slow penetrators. Since it takes at least ten minutes to get through the skin, a quick splash across a suspect stream should do you no harm; vigorous towelling dry after bathing also kills any parasites caught in the act of skin penetration.
It took years of traveling to develop an efficient laundry technique. Try this. Keep your clothes on in the shower. Get soaked. Turn off the shower. Then rub yourself (and your clothes) all over with soap. You can then either continue showering to rinse the clothes before taking them off, wringing them out, and hanging them to dry or you can remove them for an extra-thorough rub under the shower to get rid of those nasty stains and smells.
People suffering from bilharzia pass eggs in their urine or feces, and if these enter suitable, well oxygenated freshwater, they will hatch out and swim off in search of a snail to infest. [...] Travelers are infected when swimming, paddling, or even showering in waters contaminated with human waste, which usually means that the victim has paddled or swum within 200 yards of a village or point where people use water - for washing clothes perhaps, or where village children romp. [...] The highest-risk geographical regions are the great lakes of the east African Rift Valley, but the infection can be acquired from many freshwater lakes, streams, and slow-moving rivers where there is waterweed for the snails to feed on. There are foci in the Middle East, and in the tropical Americas (northeast Brazil, the Guianas, Surinam, Venezuela, and some Caribbean islands.
The reputations of many "dangerous" beasts seem exaggerated, although tropical South American rivers can harbor stingrays which can cause exceedingly nasty injuries.
It seems to have been the hyperbolic accounts published by Theodore Roosevelt that are the basis of the fearsome reputation of the piranha: there are no reliable accounts of human deaths due to these fish.
Some trekkers and mountaineers take acetazolamide (Diamox) capsules to speed acclimatization and reduce high altitude insomnia; this medicine is a mild diuretic [...] so take them in the morning otherwise you will be awakened by your bladder in the night.
In rural Bangladesh, there are millions of people, little cover, and locals find foreigners fascinating. It is impossible, therefore, for women to relieve themselves outdoors in privacy. We traveled with three large cheap black Chinese umbrellas to hide behind when I needed to go.
