CAMP HYGIENE
by Buck Tilton
In the Beginning, or shortly
after, millions of years before you arrived, they were here.
When you are gone, when we are all gone, they will probably still
be here. Everywhere you go, they go too. Everywhere you stop,
they are already waiting. They are a part of everything you do.
From the stream to the latrine, from the nose to the mouth, from
the blister to the boil, from water bottle to the lump of leftover
macaroni, they are involved.
Germs!
Cleanliness might be next to Godliness, but uncleanliness
may put you even closer, having sent more people on to the Happy
Camping Ground than all other reasons to die combined. Before
hygiene there was the Bubonic Plague, the Curse of Cholera, and
Typhoid Mary. Caused by the bacteria Yersinia pestis, the "Black
Death" alone, in a three year period, 1347 to 1350, wiped
out an estimated 25 million Europeans and laid approximately
nine-tenths of the population of England underground.
Those days of un-hygienic mass migrations to the Hereafter
are over. But poor food handling techniques, unclean food handlers,
and improper sanitation cost about 8 billion US dollars annually
in medical bills and lost wages. And germs spoil many an outdoor
experience. At the National Outdoor Leadership School (NOLS),
statistics indicate sixty percent of their students leaving a
course because they're sick got sick because of bad camp hygiene.
BY THEIR TRASH YE SHALL KNOW THEM
As any sanitation engineer can tell you, much can be learned
about a person by going through their garbage. Same goes for
backcountry trash and, in the plus column, the amount of litter
has steadily decreased in wilderness areas over the last twenty
years despite an increase in litter bearers, thank you very much.
But the potential impact of trash ranks low as a health hazard,
while the disposition of leftover food and, far more important,
human waste products rank as the greatest risk.
SHIT, BY ANY OTHER NAME, SMELLS THE SAME
You can't realistically pack out everything you pack in, except
in special circumstances (such as dragging frozen feces off of
winter trips), but you can, with an adequate poo-poo plan, reduce
the risk of fecal contamination to an absolute minimum. Transmission
of fecalborne pathogens occurs in four ways: direct contact with
the feces, indirect contact with hands that have directly contacted
the feces, contact with insects that have contacted the feces,
and drinking bad water. Human waste products breakdown to a harmless
state as a result of two mechanisms: bacterial action in the
presence of oxygen, moisture and warmth, and sterilization from
direct ultraviolet radiation. Deposition of solid body wastes
should include placement 1) to maximize decomposition, 2) to
minimize the chance of something or someone finding it, and 3)
to minimize the chance of water contamination. And, after the
deed, wash your hands.
Latrines are out, except in established spots. They concentrate
too much poop in one place. They carry a high risk of water pollution.
They invite insect and mammal investigation. They are unsightly,
and they stink. If you are ever required to dig a latrine, make
it at least a foot deep, and add soil after each deposit, and
fill it in when the total excreta lies several inches below the
surface.
For years, environment- and health-concerned wildland managers
have recommended catholes as the best thing to do with your doo-doo.
Preferably in a level spot, a cathole should be dug several inches
into an organic layer of soil, where decomposing microorganisms
live most abundantly. After you've dropped your droppings, stir
them into the soil to speed decomposition. Cover the mess with
a couple of inches of soil, and disguise the spot to hide it
from later passersby.
It was long assumed that microorganisms in near-surface soil
rapidly rendered fecal matter harmless. But then came the turd-testers,
scientists who purposefully catholed pathogen-impregnated excrement
and dug it up a year after to discover some of the pathogens
were still active.
Now it's generally considered that your Number Two will rot
to harmlessness quickest if you use the smear technique, smearing
or scattering your dung over the surface to maximize sun and
air exposure. Smears (and all human wastes) should be at least
two hundred feet, or approximately seventy adult paces, from
water, and placed where little chance of discovery exists.
The smear technique has obvious drawbacks in well-used areas
where, for one thing, waste won't decompose fast enough to eliminate
health hazards. In those places it remains best to defecate in
thoughtfully situated catholes.
URINE TROUBLE
Although urine is usually considered a sterile waste product,
it can carry, almost always in developing countries, parasites
such as schistosomes. To stay on the safe side, urinate on rocks
or in non-vegetated spots far from water sources whenever possible.
SANITATION AROUND THE NATION
Wilderness areas, despite the National Wilderness Preservation
Act, are not created equal. Some are especially wet, some dry,
some cold, and some hot. Special sanitation considerations may
be required in special environments.
LAKES AND RIVERS
Moving well away from bodies of water and carefully selecting
your poopsite will eliminate most of the health risks associated
with water contamination. But in some places, such as deep dry-country
canyons, moving well away isn't possible. In those spots, the
only safe alternative is packing it out. The most acceptable
means to do this requires a sturdy sealable can and several heavy-duty
garbage bags. Line the can, such as a large ammo box, with a
couple of garbage bags folded out over the rim. Before and after
each use, throw in some chemicals to reduce the smell and slow
decomposition. (Rapid decomposition inside a plastic bag may
produce a disgusting explosion.) Chlorox or quicklime will do.
Toilet paper goes into the bag, too, but urine should be squirted
elsewhere. Urine dilutes the added chemicals and greatly increases
bag weight. Before packing the bag for the next day's travel,
squeeze out the air and tie it firmly closed.
On some wilderness waterways, travelers are encouraged to
urinate directly into the water. In some areas, this practice
is discouraged. Follow local recommendations.
DESERTS
Human excrement won't decompose in sandy, predominantly inorganic
desert soil. Instead, it filters down through the ground. For
this reason, deposits should be made far from water sources,
out of gullies and other obvious drainages, and off of slickrock.
Insect contamination in dry regions is low, and smearing your
personal manure rates as a healthier alternative than deeply
burying it. Because it will remain visible for a long long time,
discretion is the better part of desert evacuations, and the
best all-round choice in most areas is shallow burial. High near-surface
temperatures will cook pathogens to death in short order.
ABOVE TIMBERLINE
In the frozen north and in the fragile oft-frozen high country,
decomposition goes slowly due foremost to the cold. Fecal monuments
may stand for ages. The smear technique offers the fastest decomposition
of human wastes. And sun can decontaminate and rain and snow
can wash away the smear. Once again, please choose a secluded
spot well away from water sources.
SNOW
Snow stools, no matter how far they're buried, will appear on
the surface come springtime. For that reason, proper choice of
burial sites remains of paramount importance.
FOOD FOR THOUGHT
Some leftovers haven't had the opportunity to be processed by
the human digestive system. These result from cooking more than
you can eat, which is a result, most often, of less than maximum
meal planning skills. Storage of cooked- but-uneaten food in
the wilderness poses an almost insurmountable problem. Bacteria
grows optimally at temperatures ranging from forty-five to one
hundred forty degrees Fahrenheit, and unhealthy populations of
bacteria can be reached in a brief period of time. Reheating
cooked food, although it kills bacteria, often leaves dangerous
toxins produced by the bacteria at sickening levels. Your safest
bet is to get rid of leftovers.
Buried food usually ends up being unburied by hungry animals.
If campfires are appropriate, small amounts of dry food will
burn to nothing, but wet food usually becomes an unsightly lump
of ash unless the fire is extremely hot. Scattering small amounts
of food in seldom-visited areas does not spoil the harmony of
nature, and may be considered as a safe disposal method. Leftover
food should ideally be sealed in plastic bags and packed out.
Successful fisherfolk face the question of what to do with
fish heads and guts. Scattering fish parts widely in secluded
spots probably rates as the best disposal method in most cases.
Throwing the fish remains into cold wilderness water is a poor
method of disposal since the parts will stay visible for a long
time. Where hungry bear populations are dense, water disposal
of unused fish parts might still be the best idea. It could prevent
parts of you from becoming the leftovers of a bear's meal.
Another major source of food contamination in the wilderness
is dirty utensils. Cooking and eating utensils should be boiled
daily, and cleaned prior to use in the preparation and serving
of food.
LEND A HAND, BUT NOT A DIRTY 0NE
Skin, the outer layer, is an overlapping armor of dead cells
that protect the living cells beneath. Under a microscope, this
outer layer looks like the surface of the Colorado Plateau from
thirty thousand feet: canyons and mesas, cracks and fissures.
Resident microbes are wedged firmly into the low spots. Some
of these microbes are friendly, serving to keep skin slightly
acid and resistant to other microbial lifeforms like fungi. Others,
such as S. aureus, can make you severely sick. In addition to
the residents, transient germs come and go as fortune dictates.
They can accumulate rapidly after bowel movements, and they congregate
most thickly under fingernails and in the deeper fissures of
fingertips. That's why human hands account for twenty-five to
forty percent of all foodborne illness.
Washing prior to food handling, even with detergents, does
not remove all the flora living on hands, but it does significantly
reduce the chance of contamination. For your information, science
recommends the following eight- step hand washing technique for
maximum cleanliness: 1. Wet hands with hot flowing water (100-120
degrees F). 2. Soap up until a good lather is attained. 3. Work
the lather all over the surface of the hand concentrating on
fingernails and tips. 4. Clean under fingernails. 5. Rinse thoroughly
with hot water (very important). 6. Re-soap and re-lather. 7.
Re-rinse. 8. Dry (very important).
For most of us, hot water is a rare wilderness commodity.
But you can still get clean hands with this modified backcountry
technique which substitutes germicidal soap for hot water. In
tests, adequate hand sanitation was achieved with as little as
one half-liter of water. 1. Wet hands thoroughly. 2. Add a small
amount of germicidal soap (Betadine Scrub® or Hibiclens®
will work well). 3. Work lather up, especially fingertips. 4.
Clean under fingernails (and keep your nails trimmed). 5. Rinse
thoroughly. 6. Repeat soap, lather and rinse. 7. Dry.
Sure, it's a bother . . . but so is getting sick. And even
plain old hand washing beats no hand washing.
Wilderness food usually shows up in plastic bags and food
contamination can be further reduced by pouring the food out
instead of reaching in for it. It ought to go without saying,
but here it is anyway: already-sick people should stay out of
the kitchen.
SHARING IS NOT ALWAYS CARING
Nice people are willing to share, but they may be passing around
more than their water bottle. Keep your lip balm and your toothbrush
to yourself. Personal eating utensils should stay personal. If
you can't finish your candy bar or your lunch, dispose of the
leftovers properly instead of passing your germs to someone else.
