Melamine – Now in Humans

Once again, there’s no evidence that melamine at such low levels would pose any threat to humans. (or pigs, I guess, they have other issues to worry about!). It is the lack of ingredients control, and the casual diversion of food considered unfit for pet consumption to animal feed. If you did this to some other, more dangerous contaminant, and I don’t see any reason why the same thing would not happen, we’d be in a lot more trouble. The U.S did not really learn any lessons from the mad cow scare.

In a way, I am glad this story has unfolded the way it did, slowly, and methodically up the food chain, finally reaching humans. It provides some insight into how the US government “regulates” food, and what needs to be done to shore up this program. (hint, better regulation, more money, more inspectors!). Of course, as a cat owner, (and one who had an unexplained trip to the hospital to treat said cat for puking and general stomach issues), I wish that cats were not the canary in this particular food safety scare, but I guess it really made people pay attention.

Report: Tainted hogs enter food supply – Yahoo! News

Several hundred of the 6,000 hogs that may have eaten contaminated pet food are believed to have entered the food supply for humans, the government said Thursday.

No more than 345 hogs, from farms in three states, that possibly ate tainted feed are involved, according to the Agriculture Department. It appears the large majority of the hogs that may have been exposed are still on the farms where they are being raised, spokeswoman Nicol Andrews said.

Salvaged pet food from companies known or suspected of using tainted ingredients was shipped to hog farms in seven states for use as feed. A poultry feed mill in an eighth state, Missouri, also received possibly contaminated pet food scraps left over from production. The fate of the feed made from that waste was not immediately known.

    Smoking bans in North Carolina?

    After this morning’s post about Tennessee, I got curious and wanted to see what we were doing in North Carolina on smoking bans. So, I looked up my very own NC General assembly homepage and used their full text bill search function (key word smoking!). Here’s what I found.

    In the State Senate

    Great! Senate Bill S635 will ban smoking in all public places indoors except in tobacco shops, designated smoking rooms in hotels and for “research”. Follow the progress of this bill using the bill’s very own rss feed!

    In the House

    Not so good, House bill H259 has been referred to committee. But it has giant loopholes for all bars and “private clubs”. It has its very own rss feed too.

    Observations

    1. It is good to see that my representatives Kinnaird (we share a yoga class on Monday nights!) and Insko are co-sponsors on the bills. But I live in that bastion of progressivism (in the South, anyways!) Chapel Hill/Carrboro, so this is pretty unsurprising!
    2. My question to the House is this: Why are bartenders, employees of bars and private clubs, and patrons of such establishments considered not worthy of protection from second hand smoke? As someone who goes out drinking often, this is where all my exposure to second hand smoke occurs.
    3. Kudos to North Carolina for designing an accessible and easily searchable bill repository complete with rss feeds, way to go!

    Once I hear back from Sen. Kinnaird on the prospects of legislation this session, I’ll be sure to post about it.

    Update: See this. The House and Senate bills have gotten a lot closer, and most of the loopholes are gone.

    PFOA emissions from Non stick cookware and Popcorn Bags

    Important research coming out of NY. See here for previous PFOA posts. Perfluorinated compounds are used in the manufacture of Teflon, and are bioaccumulative. The theory is that the salts left over in the manufacture (residuals) are offgassing during use, and exposing consumers to bioaccumulative compounds.

    Cast Iron, anyone!!

    Quantitation of Gas-Phase Perfluoroalkyl Surfactants and Fluorotelomer Alcohols Released from Nonstick Cookware and Microwave Popcorn Bags

    Fluoropolymer dispersions are used for coating certain cookware products and food-contact packaging to impart oil and water repellency. Since salts of perfluorooctanoic acid (PFOA) are used as a processing aid in the manufacture of many fluoropolymers, it is necessary to determine if these compounds are still present as residuals after the process used to coat nonstick cookware or packaging, and could be released during typical cooking conditions. In this study, we identified and measured perfluoroalkyl carboxylates (PFCAs), particularly PFOA, and fluorotelomer alcohols (FTOHs; 6:2 FTOH and 8:2 FTOH), released from nonstick cookware into the gas phase under normal cooking temperatures (179 to 233 C surface temperature). PFOA was released into the gas phase at 7-337 ng (11-503 pg/cm2) per pan from four brands of nonstick frying pans. 6:2 FTOH and 8:2 FTOH were found in the gas phase of four brands of frying pans, and the sources of FTOHs released from nonstick cookware are under investigation. We observed a significant decrease in gas-phase PFOA following repeated use of one brand of pan, whereas the other brand did not show a significant reduction in PFOA release following multiple uses. PFOA was found at >5 ng during the fourth use of both brands of pans. FTOHs were not found after the second use of either brand of pans. PFOA was found at 5-34 ng in the vapors produced from a prepacked microwave popcorn bag. PFOA was not found in the vapors produced from plain white corn kernels popped in a polypropylene container. 6:2 FTOH and 8:2 FTOH were measured in the vapors produced from one brand of prepacked microwave popcorn at 223 ± 37 ng and 258 ± 36 ng per bag, respectively, but not measured at >20 ng (LOQ) in the other two brands. On the packaging surface of one brand of microwave popcorn several PFCAs, including C5-C12, 6:2 FTOH, and 8:2 FTOH, were found at concentrations in the order of 0.5-6.0 ng/cm2. This study suggests that residual PFOA is not completely removed during the fabrication process of the nonstick coating for cookware. They remain as residuals on the surface and may be off-gassed when heated at normal cooking temperatures.

  • 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.

    South Asians: Watch your Heart

    Seems like us South Asians die earlier from heart attacks.

    ScienceDaily: South Asians Have Higher Levels Of Heart Attack Risk Factors At Younger Ages

    Deaths related to cardiovascular disease occur 5 to 10 years earlier in South Asian countries than in Western countries, according to background information in the article. This has raised the possibility that South Asians exhibit a special susceptibility for acute myocardial infarction (AMI; heart attack) that is not explained by traditional risk factors.

    But why?

    The prevalence of protective risk factors (leisure time physical activity, regular alcohol intake, and daily intake of fruits and vegetables) were markedly lower in South Asian study participants compared with those from other countries.

    Um, it is mainly behavioral, not genetic according to the authors, and hence can be mitigated by lifestyle changes.

    Well, I guess it is time to take a personal stock as of 1-18-2007:

    • Weight – Well, I am in the lower end of the healthy BMI.
    • Exercise – 4-5 days of 45 minutes – 1 hour per day, pretty good.
    • Food – Well, mostly good, especially if the candy can be avoided. I need to eat more vegetables, but I eat a lot of high fibre, and whole wheat food, probably not enough protein, mostly vegetarian.
    • Alcohol (1-2 drinks is apparently a heart protector) – Amen, I am a religious one drink a day partaker, more on weekends :-;
    • Smoking – Well, gave that up a while back, now to quit that occasional “party” smoke.
    • Stress – Well, not so good, this is probably the area I would need to work on the most.
    • Hypertension – Well, I am borderline on my blood pressure readings 🙁 Need to work on that.
    • Cholesterol – Still waiting for results on my physical.

    On the whole, I seem to be in decent shape. It’s good to take stock once in a while.

    The Pump handle and Diacetyl

    The Pump Handle looks at the response of various government agencies (notionally charged with protecting American people) to increasing information about the danger of diacetyl exposure, certainly to workers in the flavoring industry, and recently, to consumers of microwave popcorn. An excellent post, deserves wider reading!


    Popcorn Lung Coming to Your Kitchen? The FDA Doesn’t Want to Know « The Pump Handle

    The CDC, FDA, OSHA, EPA – federal agencies charged with protecting public health – each received a letter in July alerting them to the possible serious respiratory hazard to consumers who breathe in fumes from their artificially butter-flavored microwave popcorn. The warning should have resulted in some action by these agencies, but instead, they’ve done virtually nothing.

    It appears that the Bush Administration’s efforts to destroy the regulatory system are succeeding; the agencies seem unable to mount a response to information that a well-functioning regulatory system would immediately pursue. The agencies aren’t even trying to connect the dots.

    Read on. I moved to the US in 1997 and I’ve noticed a stark difference in the performance of the government agencies named here. I have no doubt that the agencies will eventually bounce back under the right circumstances, but it is disheartening how far agencies such as the EPA, once regarded as models of well run government (at least to a developing country!) have fallen.

    Health Canada report ties asbestos to lung cancer

    Health Canada sat for more than a year on a report by a panel of international experts that concludes there is a “strong relationship” between lung cancer and chrysotile asbestos mined in Canada.

    Health Canada received the report in March 2008, resisting calls from the panel chairman to release the findings despite his plea last fall that the delay was “an annoying piece of needless government secrecy.”

    Canwest News Service obtained the report under Access to Information legislation, but the request took more than 10 months to process.

    Vancouver Sun

    Yes, dog bites man anywhere else except Canada, which has a hard time accepting that it routinely exports products that kill people. The “annoying piece of needless government secrecy” is neither needless or annoying. It protects a dying industry with a few, powerful stakeholders in Quebec, an important swing political province, so there’s need for it! Annoying – your seat “buddy” on the bus yammering on their cellphone, cancer, well, I don’t know, you tell me!

    Expect little to change from this report. It does mention that there is little danger from “Canadian exposure levels”, conveniently forgetting that 90% of the export is to developing countries where there are fewer safeguards. This feeds into the Canadian government line that “chrysotile” is safe if used correctly. If you think this line of reasoning is familiar, it is. The tobacco industry used it routinely till recently.

    Shame.

  1. How long do you really think this has been going on? I would say for years and years. All our enemies have found out how to kill us without having a war! Just poison us from the food that we eat! Like I said, this has been going on for years….what about all the cancer levels…they have grown…all the other things that we wiped out for years are all coming back. Why you say….who has most of the diseases that are popping up? Well, China has all those diseases and now we are getting them over here! And they keep on getting richer and richer. If we can use dead road kill in our pets food and other things….what do you think China adds for all the other diseases? Yes….you are right….they have to many people that die to put them in the ground…maybe they found away to solve that problem???? Remember the movie…..(ancient green) I think that was the name. Who is to say that this is what is happening right now! Something to think about….!

  2. The first thing I said was” They are trying to see if they can get us through the food supply” And then… we… recall ‘all’ of it only to feed it to another species! Duh! Humans are so stupid and self centered.

  3. Only simple greed at work, I don’t think there’s any malevolence on the part of any one involved. It’s a pretty common practice in every industry to use different quality grades of raw materials for different purposes. it is strange in this case that pets and pigs have different standards, they’re both animals!

    The FDA will hopefully uncover the extent of the problem (few bad apples, or all of China), and put some more controls into place. Melamine as an adulterant is a new problem, and while it points to a lack of ingredients control in our food manufacturing, it will monitored for, and taken care of soon. But without a comprehensive testing program in place, we’re always going to be reactive, not proactive.

  4. IMHO until we stop over processing our food chain these scare will continue – we must get away from this “chemicalisation” of food…for us OR our pets
