Student Sleuths Raise Questions about Food Labelling
January 29th, 2010 | No Comments | Source: LA TimesHow’s this for a cool high-school science project?
Brenda Tan and Matt Cost, a pair of students at Trinity High School in Manhattan, recently performed DNA analysis of food items and other objects collected in their homes and surrounding environs.
They found a hellacious mix of mislabeled and possibly tainted food items and raised a ton of questions in the process.
Among their notable discoveries:
- A pricey chunk of so-called sheep’s milk cheese turned out to have been derived from cow’s milk,
- Fish labeled smelt turned out to be Japanese anchovy,
- “Venison” dog treats were actually made from beef
- Sturgeon caviar samples contained DNA from that widely-known delicacy, the Mississippi paddlefish.
The students dubbed their project “DNAHouse.” They analyzed their collections using the Barcode of Life Database which is normally used in species identification. They secured help from DNA barcoding experts at Rockefeller University and the American Museum of Natural History for their project.
A write-up of their work appears here.
“We do not know where or why the mislabeling occurred, but most cases appeared to involve substitution of a less expensive or less desirable item, suggesting the possibility of deliberate mislabeling for economic gain,” the authors wrote. “We also think mislabeling is a serious problem because certain individuals have allergies or dietary restrictions regarding certain foods.”
Trinity has a track record for producing these kinds of stories. Last year, 2 other Trinity students created a stir by reporting that one-quarter of the fish at local markets and restaurants was mislabeled.
Of note, Tan and Cost also sampled hair from several classmates. “We were happy to report,” they wrote, “that our classmates came back as 100% human.”




The new policy requires the CIA, FBI, NSA and the US military to convince the attorney general and a team of lawyers at Justice that the release of information regarding such tactics presents a significant risk to “national defense or foreign relations,” according to the
The ensuing debate about whether such activities ought to be outsourced has been on a low-boil ever since.
The information includes lists of people with HIV, FBI photos of a Mafia hit man, the names of people in the federal witness protection program and the safe-house location for Laura Bush, according to testimony provided last week to the House Oversight and Government Reform Committee.
These officials indicate there has been significant and systemic, although possibly inadvertent “overcollection” of domestic communications involving people living in the US.
The result was that the agency was targeting US citizens and domestic communications without warrants.

The intruders have not attempted to bring down the grid, but one official told the
“Our own infrastructures are as vulnerable as (our) foreign counterparts,” warned Director of National Intelligence Dennis Blair.
During his campaign to “change Washington,” the Big O frequently accused Bush of wantonly ignoring public disclosure rules and flaunting the state-secrets privilege at will.
It has even intimated it might abscond with classified documents currently in the court’s custody to prevent the charity’s lawyers from perusing them.
That prompted several Somali American families from Minneapolis to come forward.
Shortly after Russia’s brazen denial-of-service attack knocked Kyrgyzstan off the grid for a week, the impoverished nation’s president announced he was closing Manas Air Base, the US’ last remaining facility in Central Asia.
Cyber aggressors would likely cruise past such defenses without breaking a sweat, if they haven’t already.
