Food Safety in the USA - How safe is your food?

US Moves to Improve Food Safety


More steps are being taken to improve U.S. food safety.  The Agriculture Department unveiled new regulations April 5 that would force meat and poultry companies to delay shipments to consumers until government inspectors get results of products they have tested for E-coli bacteria and other contaminants.  The move is an effort by the government to prevent outbreaks of food poisoning and reduce the number of costly product recalls.

New regulations

The U.S. Centers for Disease Control and Prevention estimates one-in-six Americans are sickened after eating contaminated food and 5,000 die every year.   During the past several years’s outbreaks of E-Coli and Salmonella poisoning have led to massive food recalls of ground beef and other things like spinach, tomatoes and eggs.

"People are alarmed when they see these kinds of outbreaks and they want the food industry to do something," Robert Brackett, a food industry analyst said.

Now the food industry and the U.S. Agriculture Department have established tougher regulations to keep contaminated items out of the food supply.  Meat and poultry products will be prevented from reaching consumers for 24 to 48 hours until government inspectors have the opportunity to review tests to help ensure consumers are getting the safest food possible.   Government researchers believe if the new guidelines had been in place two years ago more than 44 serious food recalls could have been prevented.

Long-term heath outcomes

"It is much more important to prevent the product from going into the marketplace than it is to recall it after it's been there," said Pat Buck, who founded the Center for Foodborne Illness, Research and Prevention in 2006. Buck made the decision several years after her grandson Kevin died from eating food tainted with E-coli bacteria.

Buck says serious foodborne illness is not just about having an upset stomach.

"It can also lead to a whole host of long-term health outcomes.  One reason we formed our organization was to start examining and looking at those long-term health outcomes," Buck explains.

Improving infrastructure

Other food safety advocates say the U.S. system is stronger since President Barack Obama signed The Food Safety Modernization Act into law last January.  It represented the first major overhaul of the nation's food safety infrastructure in more than 70 years.  The act requires companies to stop contamination before it happens by increasing inspections at food processing facilities and forcing companies to recall tainted products.  Buck says the tougher rules will have a big impact.

"Definitely it will save lives.  Will it make our food safe tomorrow morning?  No," she said. "This is a major change that means we are going to have to develop regulations and we are going to have to find resources to put the new programs in place."

Buck says it could take 10 years before significant changes to the nation's food safety system are in place.  In the meantime, she says her organization will continue working to encourage more research and raise public awareness about foodborne illness and making the food we eat safer.

Cell Phone Use Can Impact Brain Activity - New Study

Zapped: Why Your Cell Phone Shouldn't Be Your Alarm Clock and 1,268 Ways to Outsmart the Hazards of Electronic Pollution
New Study: Cell Phone Use Can Impact Brain Activity
Wednesday, February 23rd, 2011 - VOA

Scientists say using a cell phone for prolonged periods can change your brain activity — but they still do not know whether those changes are harmful.

In a new study released Tuesday, scientists at the National Institutes of Health used brain scans to see what happened when someone listened to the phone for at least 50 minutes. They compared those images to brain scans of the same people holding a phone next to their ear without turning it on.

They found the area of the brain nearest the phone antenna showed an increase in brain glucose metabolism — a measure of brain activity — when the phone was turned on. That portion of the brain used 7 percent more energy than when the phone was turned off.

Cell phones emit high frequency electromagnetic waves — a form of radiation — in order to connect to the cellular network. As noted by the editors of The Journal of the American Medical Association, where the study was published, the “dramatic increase” in cell phone use has led people to worry prolonged exposure to the radiation could be bad for people's health.

There have been some reports linking cell phone use and brain tumors, but the evidence is inconsistent.

The researchers in this study said their results were interesting, but still do not prove the radiation actually has any long-term harmful impact.

They said further study was necessary.
