Melamine – The FDA Says the Right Things

But can it follow up?

FDA limits Chinese food additive imports – USATODAY.com

The Food and Drug Administration is enforcing a new import alert that greatly expands its curtailment of some food ingredients imported from China, authorizing border inspectors to detain ingredients used in everything from noodles to breakfast bars.

The new restriction is likely to cause delays in the delivery of raw ingredients for the production of many commonly used products.

Inspectors are now allowed to detain vegetable-protein imports from
China because they may contain the chemical melamine. Melamine, used in
the manufacture of plastics, was found in the wheat gluten and rice
protein concentrate that has led to the recall of 5,300 pet food
products.

Good, and about time. The FDA cites “control issues” in issuing this alert.

Now for the products to reach U.S. foodmakers, the importers will have
to prove to the FDA that they are safe. The ingredients restricted
include wheat gluten, rice gluten, rice protein, rice protein
concentrate, corn gluten, corn gluten meal, corn by-products, soy
protein, soy gluten, mung-bean protein and amino acids.

Excellent stuff, exactly what was needed, to put the onus on the manufacturer to prove safety. Here’s the FDA’s press release.

The onus, of course, is on enforcement. Can the FDA identify every item on this list, and quarantine it until a certificate is produced? Can it subject a random number of these products to independent verification to avoid cheating? Does it have the resources? Does it have the inspectors? Stay tuned.

  • U.K Hospitals – Get that filthy tie out of here!

    It may be no surprise to some that doctors frequently transmit diseases amongst patients in hospitals. And bugs in hospitals, raised on a steady diet of antibiotics, tend to be hardy, drug resistant and deadly. Among the many sensible things doctors need to do (ahem, wash your hands doc!), turns out that the clothes you wear make a difference. So, in the U.K, where they worry about these things, doctors are being issued a dress code. Read on for some biting criticism of that most pointless of neck appendages.

    U.K. hospitals issue doctors’ dress code – Yahoo! News

    “British hospitals are banning neckties, long sleeves and jewelry for doctors — and their traditional white coats — in an effort to stop the spread of deadly hospital-borne infections, according to new rules published Monday.

    Hospital dress codes typically urge doctors to look professional, which, for male practitioners, has usually meant wearing a tie. But as concern over hospital-borne infections has intensified, doctors are taking a closer look at their clothing.

    ‘Ties are rarely laundered but worn daily,’ the Department of Health said in a statement. ‘They perform no beneficial function in patient care and have been shown to be colonized by pathogens.’

    Please frame that statement, ties are pointless, ties perform no beneficial functions, down with ties!

    March Babies not so Bright? – Pesticides to Blame?

    An Indiana scientist makes a rather provocative argument that exposure to pesticides in the womb can explain why Indiana babies conceived in July-August (Born March and April?) have lower achievement scores than the other kids.

    ScienceDaily: Conception Date Affects Babys Future Academic Achievement

    Dr. Winchester and colleagues linked the scores of the students in grades 3 through 10 who took the Indiana Statewide Testing for Educational Progress (ISTEP) examination with the month in which each student had been conceived. The researchers found that ISTEP scores for math and language were distinctly seasonal with the lowest scores received by children who had been conceived in June through August.

    “The fetal brain begins developing soon after conception. The pesticides we use to control pests in fields and our homes and the nitrates we use to fertilize crops and even our lawns are at their highest level in the summer,” said Dr. Winchester, who also directs Newborn Intensive Care Services at St. Francis Hospital in Indianapolis.

    “Exposure to pesticides and nitrates can alter the hormonal milieu of the pregnant mother and the developing fetal brain,” said Dr. Winchester. “While our findings do not represent absolute proof that pesticides and nitrates contribute to lower ISTEP scores, they strongly support such a hypothesis.”

    Well, that is a bold leap of faith, and use of a correlation=causation argument that I don’t appreciate in most cases. Has this kind of work been done in other countries, or in urban environments without pesticide use?

    I am sure that many chemicals have subtle, but significant effects on developing fetuses. And the chemicals the authors mention have links with hypothyroidism..

    Nitrates and pesticides are known to cause maternal hypothyroidism and lower maternal thyroid in pregnancy is associated with lower cognitive scores in offspring.

    There is a link, but without further data, I think the conclusions are a stretch. But, something to keep in mind I guess if you live in Indiana and want to plan a baby!

    Disclaimer: I was conceived in June, and was in the upper echelons of achievement through school. So, by the power of personal experience, I am predisposed to scepticism. OTH, I grew up in a big city with consistently high pollution levels throughout the year and not much pesticide exposure.

    ES&T Online News: E-waste recycling spews dioxins into the air

    ES&T Online News: E-waste recycling spews dioxins into the air

    When computers, televisions, music systems, and other electronic products reach the ends of their lives, they often end up in China or other developing countries as e-waste. Such waste is a serious environmental threat in these parts of the world because of the poorly regulated conditions under which the waste is dismantled. A new study published in ES&T (DOI 10.1021/es0702925) shows that Guiyu, a major e-waste recycling center in China, has the highest documented levels of atmospheric polychlorodibenzo-p-dioxins (PCDDs) and polychlorodibenzofurans (PCDFs) in the world.

    In e-waste recycling centers in China, discarded products are dipped into open pits of acid and heated over grills fueled with coal blocks to extract precious metals, such as gold. These processes often release toxic metals, such as lead, and organic compounds, such as dioxins. The emissions are not regulated, and occupational exposure is high because of the poor working conditions for e-waste recycling laborers.

    In March 2007, researchers at Hong Kong Baptist University showed that soil at e-waste recycling sites in China has high levels of dioxins and polybrominated diphenyl ether (PBDE) flame retardants. (Read the paper at ES&T‘s ASAP website.) More recently, another study published in ES&T showed that the workers at these sites have blood levels of the heavy PBDE, BDE–209, 50–200 times higher than those previously reported. Whereas dioxins are potentially carcinogenic for humans, PBDEs affect thyroid metabolism and brain development.

    In the current study, Ping’an Peng of the Guangzhou Institute of Geochemistry (China) and his colleagues sampled the air from Guiyu for a week in both the summer and the winter and analyzed the samples for 2,3,7,8-PCDD/Fs. The levels varied between 64.9 and 2765 picogram per cubic meter (pg/m3). The toxic equivalents (TEQ)—a value used to account for the different levels of toxicity of the individual dioxins—was 0.909–48.9 pg TEQ/m3. Given that Guiyu has no municipal or medical solid-waste incinerators, which are known to be major sources of dioxins, the authors attributed the elevated dioxin levels to e-waste recycling.

    The team also found that the dioxin concentrations in the air around Guiyu were 12–18 times higher than those in Chendian, a town 9 kilometers (km) from Guiyu, and 37–133 times higher than those in Guangzhou, which is 450 km from the e-waste site. The results suggest that dioxin pollution from e-waste recycling is spreading to nearby areas.

    When they calculated the exposure of adults to dioxins through inhalation, the researchers found that it (68.9 and 126 pg TEQ per kilogram per day in the summer and winter, respectively) was a whopping 15–56 times higher than the World Health Organization recommended maximum of 1–4 pg TEQ/kg/day.

    Black Lung – Miners pay so you can get more coal

    The Pump Handle alerts us to a special report on coal miners and their lungs, not for the faint of heart, but something to keep in mind when you hear the phrases “Cheap Energy” and “coal” in one sentence, it’s not so cheap for these people.

    Black Lung: Dust Hasn’t Settled on Deadly Disease « The Pump Handle

    Louisville-Courier Journal reporters Laura Unger and Ralph Dunlop offer us the voices and faces of miners who are suffering from coal workers’ pneumoconiosis. Their special report, Black Lung: Dust Hasn’t Settled on Deadly Disease, includes an on-line version which features five compelling videos featuring 40- and 50-year old coal miners who are now suffering with the disabling lung disease. Mr. Danny Hall, 56, for example, who is still severely impaired despite receiving a lung transplant says “if I had to do over, I wouldn’t ever go into coal mining.”

  • Smoking bans

    If you followed the failed attempt in North Carolina this year to ban smoking in indoor public spaces, one of the so called arguments was the famous slippery slope one, that this was only a prelude to banning smoking “in the comfort of your own home”, and other attendant property rights arguments. Well, it turns out that there is an impromptu smoking ban in place in most homes already!

    Study: Smoking forbidden in most U.S. households – CNN.com

    Smoking is forbidden in nearly three out of four U.S. households, a dramatic increase from the 43 percent of homes that prohibited smoking a decade ago, the federal government reported Thursday.

    Before anyone makes the property rights argument that this “ban” is by choice, and not by government fiat, let me make it, and break it. Smoking falls into the category of occupational and reccreational exposure to pollution that harms and kills. It’s no different from lead in the water or smog as far as the non-smoker is concerned. So, property rights are not polluter rights, sorry.

    It’s only a matter of time before smoking indoors is considered completely and utterly unacceptable, kinda like smoking in airplanes!
