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.

EPA’s ban on high-risk uses of trichloroethylene needs to get over the finish line

By Jennifer McPartland / Published: March 31, 2017

Jennifer McPartland, Ph.D., is a Senior Scientist with the Health Program.

Trichloroethylene, or TCE for short, is a very toxic chemical. No doubt about it. Among other health effects, TCE is known to cause cancer and interfere with development.  It is also toxic to the immune system and kidneys. While the vast majority of TCE in the U.S. is used to make other chemicals (i.e., is used as a chemical intermediate), approximately 15% of TCE has other commercial and consumer purposes, including as a metal degreaser and spot cleaning agent.

Over the past several years, the Environmental Protection Agency (EPA) took a hard look at exposures and potential health risks—including to workers, consumers, and bystanders—resulting from certain commercial and consumer uses of TCE. It found clearly excessive risks from these uses, which prompted the agency to take steps to reduce these exposures.

In December 2016, using its authority under section 6 of the Toxic Substances Control Act (TSCA), EPA proposed a rule to ban the use of TCE as an aerosol degreaser and as a spot cleaning agent in commercial dry cleaning facilities—marking the first time in nearly 3 decades it has tried to restrict a chemical under TSCA. A second proposed rule to ban the use of TCE as a vapor degreaser followed a month later in January 2017 and is undergoing public comment.

The public comment period on the first TCE proposed rule closed recently. EDF filed extensive comments urging the agency to finalize the rule as soon as possible.

Getting the framework right for the new TSCA: EDF comments filed on key EPA proposed rules

By / Published: March 21, 2017

Richard Denison, Ph.D., is a Lead Senior Scientist.  Lindsay McCormick is a Project Manager.  Jennifer McPartland, Ph.D., is a Senior Scientist.

Environmental Defense Fund (EDF) filed extensive comments yesterday on the Environmental Protection Agency’s (EPA) proposals for the two most central “framework” rules mandated by last year’s Lautenberg Act amendments to the Toxic Substances Control Act (TSCA).

Our comments address these proposed rules:

Both sets of comments address many different provisions of the proposed rules.  EDF indicated our strong support for many aspects of the proposals, but urged changes to a number of provisions that we cannot support as proposed.  In addition, we identified provisions we believe need to be added to EPA’s rules to be consistent with or meet the requirements of the Lautenberg Act.

EDF emphasized how vital it is for EPA to meet its June 22, 2017, statutory deadline for promulgating these rules.  Because they establish processes that will require several years to begin to yield decisions on specific chemicals, delays in promulgating them in final form so that the processes can commence in the timeframe Congress intended will only serve to undermine public confidence in the new law, counter business interests to restore confidence in the chemicals marketplace, and hamper EPA’s ability to carry out its new mandates.  This is especially the case, given EPA’s appropriate recognition in both proposed rules that it will need to initiate measures as soon as possible to ensure that sufficient information will be available to inform prioritization and risk evaluation decisions.

As discussed in more detail in the comments, EDF strongly supports EPA’s decision not to codify specific scientific policies, procedures and guidance in these rules.  To do so would not be consistent with the law and would more generally represent bad policy.  EDF also agreed with EPA’s proposal not to define in its rules complex, science policy-laden terms such as “weight of the scientific evidence,” “best available science,” and “unreasonable risk.”  These concepts are best elaborated on in guidance and policy statements and best understood in the context of specific decisions on chemical substances.

Some other highlights from each set of EDF’s comments follow.   Read More »

Dad’s lead-laden hair dye could impact the whole family: FDA to consider barring lead compound in widely-used men’s hair dyes

By Jack Pratt / Published: February 27, 2017

Jack Pratt is Chemicals Campaign Director

Today, EDF joined a group of advocates in filing a petition that could force a ban on lead in hair dyes. Over the last several decades, we have gone to great lengths to reduce lead exposure—from eliminating the use of lead in gasoline, to tackling legacy uses in paint and water pipes. Yet, somewhat incredibly, lead is still permitted in hair dyes in the United States. Unfortunately, the evidence indicates that use can have an impact not only on the men who use it (it is seemingly exclusive to men’s dyes) but can have an impact on kids in the house too. That’s why FDA should take action and reverse their decades-old approval of lead in hair dyes.

EPA to consider perchlorate risks from degradation of hypochlorite bleach

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: February 3, 2017

Tom Neltner, J.D., is Chemicals Policy Director and Maricel Maffini, Ph.D., Consultant

Virtually all types of food contain measurable amounts of perchlorate. Young children are the most highly exposed, and they consume levels that may be unsafe. Reducing exposure to perchlorate is of public health importance because it presents a risk to children’s brain development

One potentially significant source of the toxic chemical in food is hypochlorite bleach that, when not well managed, degrades to perchlorate. Bleach is used to sanitize food manufacturing equipment or to wash or peel fruits and vegetables. Thanks to a recent decision by Environmental Protection Agency’s (EPA) Office of Pesticide Programs, we will better understand the risk posed by perchlorate-contaminated bleach and whether standards are needed to improve the management of bleach.

Reduce perchlorate exposure by improving bleach management

In 2011, an excellent report by the American Water Works Association (AWWA) and the Water Research Foundation documented that hypochlorite bleach degrades into perchlorate. The report also included guidelines on better management of hypochlorite to preserve its effectiveness for drinking water utilities using it to disinfect water.

Most of AWWA’s recommendations are equally relevant to food manufacturers and anyone using bleach to disinfect food contact surfaces. The key recommendations are:

  • Dilute hypochlorite solutions on delivery. Cutting the concentration in half decreases the degradation rate by a factor of 7.
  • Store hypochlorite solutions at lower temperatures. Reducing temperature by 5oC decreases degradation rate by a factor of 2.
  • Keep pH between 11 and 13 even after dilution.
  • Avoid extended storage times, and use fresh hypochlorite solutions when possible.

The objective is not to reduce the use of bleach. Rather it is to preserve its effectiveness by preventing degradation to perchlorate through careful management.

Too many young children get too much perchlorate from food

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: January 27, 2017

Tom Neltner, J.D., is Chemicals Policy Director and Maricel Maffini, Ph.D., Consultant

On January 9, we described a new Food and Drug Administration (FDA) report showing that perchlorate exposure to infants and toddlers increased 34% and 23% respectively between the years around 2005 and 2010. Young children were the most exposed age groups. FDA compared the exposure to a “safe dose” established in 2005 and saw no cause for concern. We respectfully disagree and find the levels alarming. First, we now know that the 2005 “safe dose” is no longer sufficient to protect children’s brains from the irreversible harm that can result from even transient exposures to perchlorate. Second, many young children may be over the “safe dose.” Read More »
