Current Carbon Monoxide Standards Protect Health: EPA
Current U.S. national air quality standards for carbon monoxide
(CO) protect public health and the environment, according to the
Environmental Protection Agency.
The agency also said that levels of CO in the air have fallen by
80 percent since 1980, mostly due to motor vehicle emissions
The current health standards are 9 parts per million (ppm)
measured over 8 hours, and 35 ppm measured over 1 hour. CO levels
at monitors across the country are well below the standards.
CO is a colorless, odorless gas that can harm health by reducing
oxygen delivery to the body's tissues and organs, including the
heart and brain, the EPA said.
Revised air monitoring requirements to be implemented in the
next few years will require CO monitors to be placed near roads in
52 urban areas with populations of 1 million or more. This will
provide the EPA with data about CO levels that may be affecting the
health of people who live in neighborhoods near busy roads.
Not All Obese People Unhealthy: Studies
Some obese people may be healthy and don't need to lose weight,
two new studies suggest.
They challenge the common belief that body mass index (BMI) and
weight determine health,
CNN reported. One group of researchers estimated that one in
five obese people may not have medical issues.
But it can be difficult to distinguish between the "healthy
obese" and obese people who currently don't have weight-related
health issues but may develop them in the future.
"Our study challenges the idea that all obese individuals need to lose weight," said Dr. Jennifer Kuk, assistant professor, School of Kinesiology & Health Sciences at York University in Toronto, CNN reported.
The studies were published in the
Canadian Medical Association Journal and
Applied Physiology, Nutrition and Metabolism.
Ground Beef Recalled
About 60,000 pounds of ground beef sold mainly in the
southeastern United States have been recalled because it could be
tainted with E. coli bacteria.
The recall of the meat from National Beef Packaging Co. of Dodge
City, Kan. was announced after the Ohio Department of Agriculture
detected the bacteria during routine testing, the
Associated Press reported.
At least three major grocery store chains -- Winn-Dixie Stores
Inc, Publix Super Markets Inc., and Kroger Co. -- have recalled
packages of the ground beef sold mainly in Alabama, Florida,
Georgia, Louisiana, Mississippi, South Carolina and Tennessee.
The companies advised consumers to return the ground beef to
their stores for a full refund, the
There have been no reports of illnesses, according to the U.S.
Department of Agriculture.
Bat on Flight Causes Rabies Concerns
U.S. health officials are concerned about possible rabies
exposure among 50 airline passengers who may have had contact with
a bat that was on an Aug. 5 Delta flight from Madison, Wis. to
The airliner returned to Madison after the bat appeared, but
it's not known if the bat had rabies because it escaped after the
plane landed, the
Associated Press reported.
The Centers for Disease Control and Prevention is trying to
reach all the passengers who were on the 6:45 a.m. flight 5121 in
order to make sure they didn't have close contact with the bat.
As of last Friday, the CDC had talked to only 13 of the
passengers and is asking the other passengers to call
Excess Fat Affects Body's Sugar Sensors: Study
A high-fat diet can trigger type 2 diabetes by interfering with
the body's sugar sensors, according to a new study.
Being overweight is one of the main risk factors for type 2
diabetes. Learning more about the link between fat and type 2
diabetes could help lead to a cure, according to the researchers at
the University of California and the Sanford-Burnham Medical
BBC News reported.
The study, conducted with mice and human pancreatic cells,
appears in the journal
The findings are interesting and this is a "theory worth
investigating further," Dr. Iain Frame, director of research at
Diabetes UK, told
