Announces New Drinking Water Standard to Protect Hundreds of Millions |
|
Chinese health
officials have approved a stricter national standard for the quality
of drinking water that will add new benchmarks and greatly improve
upon the 1985 standard. Officials see this as the next step to
bringing clean drinking water to the hundreds of millions of Chinese
who currently do not have access.
Tap water
in China is generally viewed as unsafe to drink. Health officials
believe this standard will raise the quality of tap water and alleviate
the public's fear of untreated water. Although the government has
continually pledged to clean up the water supply, the situation
has continued to deteriorate over the years. The 2008 Olympics
in Beijing have spurred a strong push for cuts in air and water
pollution.
The tainted
drinking water is caused by polluted waterways and contaminated
coastlines. Industrial and farm chemicals, in addition to domestic
sewage, have also contaminated the water.

Adopts New Drinking Water Standard

| Warm
Months See an Increase in Deadly Seawater Bacteria |
|
The number of
reported infections caused by Vibrio vulnificus, a bacteria
found in warm seawater that can cause severe gastrointestinal illness,
skin lesions and even death, is on the rise in certain parts of
the country. Researchers believe that higher water temperatures
and salinity in waters where shellfish are harvested, are behind
the increase in states around the Gulf Coast and Chesapeake
Bay area.
Vibrio infections
can occur from ingesting raw or undercooked shellfish, including
oysters, clams, mussels or crabs. However, when skin wounds are
exposed to the bacteria in warm seawater, fast-spreading and potentially
deadly skin lesions are possible. If skin becomes red, tender,
or painful, rubbing alcohol is recommended. If the infection continues,
antibiotics are needed quickly. Since the bacteria are mainly found
in shallow inlets rather the ocean itself, fishermen and those who
wade into brackish water are most at risk. Additionally, people
with compromised livers or immune systems are most vulnerable,
as are those who drink a lot of alcohol.
The U.S.
Centers for Disease Control and Prevention estimates 8,000 Vibrio
infections and approximately 60 deaths related to infections may
occur annually in the United States. During 2003-04, the CDC
reported that 47 Vibrio vulnificus cases associated with
recreational activities in water, rather than food, were reported
from 16 states. As a result, forty-one people were hospitalized
and six died.

Updates Measures to Prevent Disease from Public Animal Interactions
|
|
The CDC has
released its most recent recommendations for avoiding the spread
of infectious disease resulting from human and animal interaction
in public situations. Petting zoos, fairs, vegetable and fruit
stands with animal displays and educational exhibits, among other
locations, create possibilities for infectious disease outbreaks,
rabies exposures, injuries, and other human health problems.
The report provides recommendations for public health officials,
veterinarians, animal venue staff, animal exhibitors, visitors to
animal venues, physicians, and others concerned with minimizing
risks associated with animals in public settings.
Those who
come in contact with animals in public venues are advised that hand
washing is the most imperative step to reduce the risk of disease
transmission. The CDC also recommends that those in charge of
animal areas should not allow food in animal areas. Venues need
to include transition areas between animal areas and non-animal
areas. Furthermore, animals must be properly cared for and managed.
Visitors, according to the report, need to be informed about
disease risk and prevention procedures before animal interaction
occurs to minimize possible health consequences from the interactions.
Since 1991,
approximately 50 human infectious disease outbreaks involving animals
in public settings have been reported to the CDC. Previous outbreaks
reported include Salmonella, Cryptosporidium, Coxiella burnetii,
Mycobacterium tuberculosis, ringworm, and other pathogens.

| World
Health Organization Releases Guidelines for Water Desalination Process |
|
The World Health
Organization (WHO) is developing new guidelines to address the growth
of water desalination as a major source of drinking water. A
new draft document speaks to both drinking water quality and environmental
protection issues in order to aid both current and future desalination
facilities. Desalination technologies, which purify waters impaired
with salts or other contaminants, were introduced 50 years ago.
While the majority
of typical drinking water treatments use current WHO guidelines
as a quality standard, desalination is used on non-typical water
sources and existing guidelines may not adequately address the unique
factors of the process. More than 12,000 desalination plants operate
across the globe and produce approximately 40 million cubic meters
of water per day.
The number
of desalination operations is growing rapidly as the worldwide need
for drinkable water grows more acute. Technologies continually
improve and, as a result, the cost of each unit drops. The desalination
market is predicted to grow by 12% per year through 2010.

full draft, please see:
