The hidden – and potentially dangerous – chemicals in your diet

Tom Neltner, J.D.is Chemicals Policy Director

While picking up groceries for the week, a shopper may compare brands, prices, and nutritional information to ensure they make economical and healthy choices for their family. Unfortunately, there’s much more to our food than meets the eye – or makes the label.

Approximately 10,000 food additives are allowed in our food. Food additives are substances used to flavor, color, preserve, package, process, and store our food. While some of the chemicals added to food or used in packaging are harmless, others are downright dangerous and linked to health concerns. Certain additives are linked to reproductive problems, developmental issues, and even cancer.

Perchlorate was approved in 2005 as a component of plastic packaging for dry food despite the fact that it is a known endocrine disruptor that impairs infant brain development. Benzophenone – an artificial flavor added to baked goods, dessert, beverages, and candy – is classified as a possible human carcinogen. The list goes on. No matter where you shop, your family’s health may be at risk.

Check out the cupboard below to see what else could be lurking in your food.

National Academy of Sciences strongly affirms science showing styrene is a human carcinogen

Richard Denison, Ph.D., is a Lead Senior Scientist. 

It’s been a ridiculously long road to get here, because of the delay tactics of the chemical industry.  But yesterday a panel of the National Academy of Sciences (NAS) fully backed the National Toxicology Program’s (NTP) listing of styrene as “reasonably anticipated to be a human carcinogen.”

We have blogged earlier about this saga.  In June 2011, after years of delay, the NTP released its Congressionally mandated 12th Report on Carcinogens (RoC), in which it upgraded formaldehyde to the status of “known to be a human carcinogen,” and for the first time listed styrene as “reasonably anticipated to be a human carcinogen.”  The chemical industry launched an all-out war to defend two of its biggest cash cows, filing a lawsuit to try to reverse the styrene listing (which it lost), and seeking to cut off funding for the RoC.  

In late 2011, the industry managed to get its allies in Congress to slip into the Consolidated Appropriations Act of 2012, without any debate, a rider that mandated NAS to review the styrene and formaldehyde listings in the 12th RoC.  Yesterday’s NAS report on styrene is the first installment, with the second one on formaldehyde expected shortly.

The NAS report could not be more supportive of the NTP’s listing of styrene, finding “that ‘compelling evidence’ exists in human, animal, and mechanistic studies to support listing styrene, at a minimum, as reasonably anticipated to be a human carcinogen.” (emphasis added)  Read More »

The chemical industry says formaldehyde and styrene don’t cause cancer. Only one of 52 scientists agree.

Richard Denison, Ph.D., is a Senior Scientist.

Last week, the National Academy of Sciences (NAS) held a joint meeting of its two panels that are charged with reviewing the listings of formaldehyde and styrene as carcinogens in the 12th Report on Carcinogens, which was released in June 2011.

The 12th Report on Carcinogens (RoC) is the latest edition of a Congressionally mandated report developed by the National Toxicology Program (NTP).  It upgraded formaldehyde to the status of “known to be a human carcinogen,” and for the first time listed styrene as “reasonably anticipated to be a human carcinogen.”  That put the chemical industry into a real tizzy, what with the threat these listings pose to its profits from the huge volumes of these cash cows sold each year, not to mention the huge potential liability it faces.

Never one to go down lightly, the American Chemistry Council (ACC) has launched an all-out assault on the NTP and the RoC.  It is waging battle not only with the executive branch, but also in the courts and in Congress.  In late 2011, it managed to get its allies in Congress to slip into the Consolidated Appropriations Act of 2012, without any debate, a rider that mandated the NAS reviews of the formaldehyde and styrene listings in the 12th RoC that are now underway.

ACC also pushed legislation in the last Congress to shut down all funding for the RoC until the reviews are completed; failing on that front, earlier this month it demanded that NTP cease all work on the next (13th) edition of the RoC.  (For more background, see previous blog posts by EDF and NRDC.)

Lost in all this kerfluffle, however, are these salient facts:

  • The formaldehyde and styrene listings are the outcome of one of the most extensive scientific assessment processes on the planet, entailing reviews by four separate groups of expert scientists for each chemical.
  • ACC as well as the public had at least three separate formal opportunities for providing input to these expert bodies.
  • Of a total of 52 votes cast by these scientific panels on the NTP’s recommended listings, 51 of those votes supported the recommendations and only one opposed them. Read More »

Hands off the Report on Carcinogens

Sarah Vogel, Ph.D., is Managing Director of EDF's Health Program.

Information, and importantly, access to reliable and objective information, is the cornerstone of a democratic society.  That is why recent efforts by the chemical industry and its allies to block Congressionally-mandated, scientific information on carcinogenic hazards by defunding the Report on Carcinogens (ROC) have many researchers and public health officials alarmed. 

Today, in a letter sent to House and Senate appropriations committee leaders, 75 occupational and environmental health scientists and professionals from around the country called on Congress to maintain funding for the ROC.  Their letter is in response to a legislative proposal that, if passed into law, would withhold funding for any work on the ROC until the National Academy of Sciences (NAS) completes its review of the listings of formaldehyde and styrene in the 12th ROC—a process the NAS has only just begun.  If such a proposal were successful, it would effectively delay public access to critical information on chemical carcinogens for years.     Read More »

Labor and public health advocates to the chemical industry: Stop bullying federal scientists!

Richard Denison, Ph.D., is a Senior Scientist.

After my long post this morning, I’ll keep this one brief:  The United Steelworkers, one of the nation’s top occupational physicians and EDF, represented by Earthjustice, have filed a motion to intervene in D.C. District Court, seeking to help defend the U.S. Department of Health and Human Services’ listing of styrene as "reasonably anticipated to be a human carcinogen."  The motion is in response to a chemical industry lawsuit attempting to force the agency's National Toxicology Program to withdraw the styrene warning, which was published in the 12th edition of the Congressionally mandated Report on Carcinogens.

Gasping for breath: Asthma-inducing diisocyanates enter our homes and schools

Johanna Katz is a Cornell Iscoll intern at EDF.  Jennifer McPartland, Ph.D., is a Health Scientist.

Toxic chemicals called diisocyanates are long-established as occupational hazards known to cause severe respiratory problems to workers who use or are otherwise exposed to them (see here).  In fact, diisocyanates are the number one cause of workplace-induced asthma (see here and here).  Recently, potential exposure of the general public to diisocyanates has grown, as these chemicals are increasingly used in consumer products.  This is certainly a troubling trend considering that the primary health effect of these chemicals, asthma, is a massive and growing public health problem, especially among children.  And some of the newest uses of diisocyanates are in products to which children are quite likely to be exposed.

Asthma is at an all-time high, affecting more than 24 million Americans, and creating astronomical health and productivity costs upwards of $20 BILLION each year.  And while diisocyanates are but one of many contributors to the increasing rate of asthma in the general population, we surely don’t need to be bringing more products containing such chemicals into our homes, schools, and workplaces. That will only make matters worse.

So what exactly are diisocyanate chemicals, where are they found, and what’s the federal government trying to do about them?  Read on to find out.  Read More »
