Campylobacter infects about 50,000 people a year in England
and Wales, far more than better-known organisms such as
salmonella. Yet until the mid-Seventies it was virtually
unheard of. epidemiologist Dr Meirion Evans.
"Drinking
bottled water has not previously been recognized as a risk factor. But it is
biologically plausible and could explain a substantial number of infections."
Campylobacter
causes stomach pains and diarrhea. But one in 1,000 sufferers develops
Guillain-Barre syndrome, which can lead to total paralysis. One in 20,000 dies.
Most cases had
been linked with eating undercooked chicken, or uncooked foods contaminated by
raw chicken.
Scientists
from the University of Wales in Cardiff investigated more than 200 cases of food
poisoning.
The results,
in the journal Emerging Infectious Diseases, reveal that up to 12 per cent of
cases could be attributed to bottled water, 30 per cent to contaminated chicken
and 21 per cent to salad.
The Natural
Mineral Water Service said bottlers already test for campylobacter, adding that
the study had failed to differentiate between mineral water from underground and
spring water, which could be polluted by agricultural waste.
Choosing tap water over bottled water may seem like a
simple choice: tap water costs much less, is safer, and
often tastes just as good, if not better. Nonetheless, many
people continue to buy bottled water, whether out of
convenience or preference.
There are numerous environmental concerns with bottled
water: the production and consumption of bottled water
consumes energy, pollutes the environment, and contributes
to global warming. Producing the plastic bottles uses energy
and emits toxic chemicals.Transporting the bottled water
across hundreds or thousands of miles spews carbon dioxide
into the air, complicating our efforts to combat global
climate change. And in the end, empty bottles are piling up
in landfills.
Bottled water also has significant social implications
for communities. Not only does bottled water contribute to a
global lack of drinking water, it also causes local
inaccessibility to water. In privatizing water, bottling
corporations limit access to an essential resource that many
believe should always be public
