Food Container Chemical Not Harmful, U.S.
Government Scientists Find
A chemical used in the making of baby bottles and other food containers
is not dangerous, U.S. Food and Drug Administration researchers have
decided.
The Associated Press reports that FDA scientists have confirmed
the agency's original decision that the chemical bisphenol A, which
hardens plastic, is not a threat to either infants or adults. The European
Food Safety Authority made a similar finding in late July.
Trace amounts of bisphenol A have been found to leach into food
containers, the FDA acknowledged, but the agency's scientists said they
found no evidence that such small amounts were harmful, the A.P.
reported.
Canada has already announced it would ban using the chemical in the
manufacture of baby bottles, and 10 states in the U.S. are considering
similar legislation, the wire service said.
The FDA findings are not the final word, according to the A.P. A
September meeting is scheduled, in which experts outside the FDA will
debate bisphenol A's safety. The FDA itself has kept the issue open.
More research is needed because “there are always uncertainties
associated with safety decisions,” the A.P. quotes the FDA as
saying.

Toxins Found in Frozen Shellfish Imported from
Ireland
Frozen mussels imported to the United States from Ireland may contain a
toxin that can cause stomach cramps, nausea and vomiting, according to the
U.S. Food and Drug Administration.
Two cases of azaspiracid toxin poisoning occurred in July in the state
of Washington, according to an FDA news release, and further examination
of other containers of “Mussels in a Garlic Butter Sauce” from the same
production lot imported by Bantry Bay Seafoods also contained the
azaspiracid toxins.
The FDA recommends that consumers discard Bantry Bay Seafood frozen
cooked products with “best before end” dates on the side of the box
ranging from January 23, 2009, to November 15, 2009: Mussels in a Garlic
Butter Sauce; Mussels in White Wine Sauce; and Mussels in Tomato and
Garlic Sauce.
The Bantry Bay Seafood products are sold frozen in 1 pound cardboard
packages in stores throughout the United States, the FDA says, and store
operators have been asked to remove them.
Azaspiracid toxins have never been found in U.S. shellfish beds, the
FDA says. They are odorless, tasteless, and can't be destroyed by
freezing, cooking, or boiling. Symptoms occur within two hours after the
seafood has been eaten and can last up to three days.

Drinking Red Bull May Cause Heart Damage:
Study
Drinking too much of the popular Red Bull energy drink may lead to
heart damage, says an Australian study that included 30 university
students, ages 20 to 24.
The researchers found that drinking just one 250ml sugar-free can of
the caffeinated drink boosted the “stickiness” of the blood and increased
the risk of blood clots. After drinking Red Bull, the students had a
cardiovascular profile similar to that of someone with heart disease, the
Times (U.K.) reported.
The results were alarming and suggest that older adults with symptoms
of heart disease shouldn't drink too much Red Bull, said study author
Scott Willoughby, of the Cardiovascular Research Center at the Royal
Adelaide Hospital and Adelaide University.
In a statement, Red Bull officials said the drink had been proved safe
by numerous scientific studies, and that it had never been banned from
anywhere it had been introduced, the Times reported.
Red Bull is sold in 143 countries but is banned in Norway, Denmark and
some other countries due to health concerns.

Teens Having Easier Time Getting Prescription
Drugs
It's easier to illegally obtain prescription drugs such as OxyContin,
Percocet, Vicodin or Ritalin than it is to get beer, say a growing number
of American teens.
Researchers at the National Center on Addiction and Substance Abuse at
Columbia University surveyed 1,002 12- to-17-year-olds and found that 19
percent said it was easier for them to obtain prescription drugs than to
get their hands on beer, cigarettes or marijuana, compared with 13 percent
a year ago, The Washington Post reported.
The study also found that 34 percent of teens who abuse prescription
drugs get them at home or from their parents.
About 25 percent of the teen respondents said marijuana is the easiest
substance to buy, and 43 percent of 17-year-olds said they could purchase
marijuana in less than an hour, The Post reported.

Gene Mutation Linked to Colorectal
Cancer
A gene mutation strongly linked to colorectal cancer has been
identified by Northwestern University researchers. People with the TGFBR1
ASE gene mutation have a 50 percent higher risk of colorectal cancer than
the general population.
“This probably accounts for more colorectal cancers than all other gene
mutations discovered thus far,” said study lead author Boris Pasche,
Agence France Presse reported.
The TGFBR1 ASE mutation results in decreased production of an important
receptor for TGF-beta, the most potent inhibitor of cell growth. A reduced
ability to inhibit cell growth means it's easier for colon cancer to
develop. The study was published in the journal Science.
“The reasonable expectation is this finding will save some lives,” said
Pasche, AFP reported. “We will be able to identify a larger number
of individuals that are at risk of colorectal cancer and, in the long
term, maybe decrease the cases of colorectal cancer and of people dying
from it by being able to screen them more frequently.”

Lack of Judgment Endangers Teen
Drivers
A lack of judgment about the risks of driving may explain why teens
have the highest crash and fatality rates of any age group, according to
Canadian researchers.
The team at St. Michael's Hospital in Toronto evaluated 262 high school
students and found they consistently underestimated the risks of driving
due to a number of mistaken beliefs, CBC News reported.
For example, the teens assumed that:
“Students need to comprehend that it is a lack of judgment, not only
lack of skill, that increases the risk of injury to oneself and others,”
said Dr. Najma Ahmed, assistant trauma director at St. Michael's, CBC
News reported.
The study was published in the August issue of the Journal of the
American College of Surgeons.
