Prevention of Traveler's diarrhea
Prevention of Traveler's diarrhea:
Diarrhea: NIDDK (Excerpt)
Traveler's diarrhea happens when you consume
food or water contaminated with bacteria, viruses, or parasites. You can
take the following precautions to prevent traveler's diarrhea when you go
- Do not drink any tap water, not even when brushing your teeth.
- Do not drink unpasteurized milk or dairy products.
- Do not use ice made from tap water.
- Avoid all raw fruits and vegetables (including lettuce and fruit
salad) unless they can be peeled and you peel them yourself.
- Do not eat raw or rare meat and fish.
- Do not eat meat or shellfish that is not hot when served to you.
- Do not eat food from street vendors.
You can safely drink bottled water (if you are the one to break the
seal), carbonated soft drinks, and hot drinks like coffee or tea.
Depending on where you are going and how long you are staying, your
doctor may recommend that you take antibiotics before leaving to protect
you from possible infection.

Travelers' Diarrhea: DBMD (Excerpt)
Travelers can minimize their risk for TD by practicing the following
effective preventive measures:
- Avoid eating foods or drinking beverages purchased from street
vendors or other establishments where unhygienic conditions
- Avoid eating raw or undercooked meat and seafood
- Avoid eating raw fruits (e.g., oranges, bananas, avocados)
and vegetables unless the traveler peels them.
If handled properly well-cooked and packaged foods usually are
safe. Tap water, ice, unpasteurized milk, and dairy products are
associated with increased risk for TD. Safe beverages include
bottled carbonated beverages, hot tea or coffee, beer, wine, and
water boiled or appropriately treated with iodine or chlorine. (Source: excerpt from Travelers' Diarrhea: DBMD)
Travelers' Diarrhea: DBMD (Excerpt)
CDC does not recommend antimicrobial drugs to prevent TD. Studies
show a decrease in the incidence of TD with use of bismuth subsalicylate
and with use of antimicrobial chemoprophylaxis. Several studies
show that bismuth subsalicylate taken as either 2 tablets 4 times
daily or 2 fluid ounces 4 times daily reduces the incidence of
travelers' diarrhea. The mechanism of action appears to be both
antibacterial and antisecretory. Use of bismuth subsalicylate
should be avoided by persons who are allergic to aspirin, during
pregnancy, and by persons taking certain other medications (e.g.,
anticoagulants, probenecid, or methotrexate). In addition, persons
should be informed about potential side effects, in particular
about temporary blackening of the tongue and stool, and rarely
ringing in the ears. Because of potential adverse side effects,
prophylactic bismuth subsalicylate should not be used for more
than 3 weeks.
Some antibiotics administered in a once-a-day dose are 90% effective
at preventing travelers' diarrhea; however, antibiotics are not
recommended as prophylaxis. Routine antimicrobial prophylaxis
increases the traveler's risk for adverse reactions and for infections
with resistant organisms. Because antimicrobials can increase
a traveler 's susceptibility to resistant bacterial pathogens
and provide no protection against either viral or parasitic pathogens,
they can give travelers a false sense of security. As a result,
strict adherence to preventive measures is encouraged, and bismuth
subsalicylate should be used as an adjunct if prophylaxis is needed. (Source: excerpt from Travelers' Diarrhea: DBMD)
