FDA-approved PFAS: A serious breakdown in assessing food additive safety

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

This blog is the fourth in a series describing information we discovered in reviewing thousands of pages from the Food and Drug Administration’s (FDA) response to our Freedom of Information Act (FOIA) of the agency’s approval of 31 Food Contact Substance Notifications (FCNs) from 2002 to 2016 submitted by six companies for 19 distinct chemical mixtures of per- and poly-fluorinated substances (PFAS).

In this blog, we identify one company’s serious breach of its obligation to provide FDA with all relevant toxicology data. While hindsight is 20/20, we have reason to believe that if FDA had had all relevant information, it would have demanded more studies potentially revealing risks that are only now coming to light with related chemicals. Though we have not completed a similar review for the other companies, we think this inadequate approach to chemical safety is not unique to a single company, and FDA should reassess all its reviews given what is now known about PFAS chemicals.

Safety assessment requirements for food additives – including food contact substances

When a company seeks FDA’s approval of food additives (including food contact substances), it is required to provide the agency with all relevant chemistry, toxicology and environmental data so it can conduct a safety assessment. While the agency typically conducts a literature search of its own and of public databases, the company that is claiming the chemical’s use is safe is obligated to include any data that is inconsistent with the company’s conclusion.

FDA reduces maximum daily limit for lead in children’s food by half

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

On September 27, 2018, the Food and Drug Administration (FDA) reduced the maximum allowed daily intake of lead for children from 6 to 3 micrograms per day (µg/day). It has also set a limit for adults of 12.5 µg/day, to protect against possible fetal exposure in women who are unaware they are pregnant and to reduce infant exposure during nursing. The agency now refers to these limits as the “Interim Reference Level” to match the Centers for Disease Control and Prevention’s (CDC) terminology for elevated blood lead levels that warrant action. FDA reports that the new level for children is the amount of lead in food expected to result in a blood lead level of 5 µg/deciliter, with a 10-fold safety factor to account for differences across the population.

This change is a major step in FDA’s new push to limit heavy metals in food to protect children’s neurological development. In April 2018, FDA explained that its Toxic Elements Working Group is “looking at all the [heavy] metals across all foods rather than one contaminant, one food at a time,” and that “even though the level of a metal in any particular food is low, our overall exposure adds up because many of the foods we eat contain them in small amounts.”

As the agency indicated earlier this year, the next step for the Working Group is to “begin reevaluating the specific lead levels that FDA has set for a variety of foods.”

One click away: We discovered just how easy it still is to purchase deadly paint strippers

Sam Lovell, Project Specialist, and Andrew ReaganCampaign Project Manager.

Methylene chloride is a deadly chemical used in common paint stripping products. It is known to have caused over 50 deaths from acute exposure – though many more likely have gone unreported. Health impacts from lower-level, chronic exposure to the chemical through use of these products, while much harder to measure, have no doubt occurred as well. Due to its health risks, the EPA proposed a rule to ban consumer and most commercial uses of the chemical in paint and coating removal products on January 12, 2017. Over a year and a half later, the ban on methylene chloride in paint strippers still has not been finalized.

As the current Administration continues to delay action on this critical ban, some companies have stepped up and committed to take paint strippers containing methylene chloride off their shelves. Unfortunately, this isn’t enough to protect all consumers or workers. We found out that it’s still shockingly easy to buy products containing the chemical from other companies – it’s a simple click away.

To figure out just how easy it is, we searched for “paint stripper” and “paint remover” on Amazon. On the first page of our search results were several products containing methylene chloride. (This information is not at all obvious to consumers – you need to read the fine print on the product description.)

EPA Updates its 3Ts Guidance for Reducing Lead in Drinking Water

Lindsay McCormick, is a Project Manager. Tom Neltner, J.D., is the Chemicals Policy Director.

Earlier this month, EPA released its updated 3Ts for Reducing Lead in Drinking Water Toolkit, which provides guidance for schools and child care facilities seeking to ensure children are safe from lead in water.  The new 3Ts – an update to the agency’s 2006 guidance – is now a web-based toolkit that includes modules, customizable templates, and factsheets.

Overall, the new toolkit is an improvement.  While the protocol itself is largely the same, the new toolkit is more user friendly and written for the non-technical audience, making it more likely that school and child care staff will use it.  EPA has also reframed the toolkit from “Training, Testing, and Telling” to “Training, Testing, and Taking Action” – placing more emphasis on the critical step of addressing lead sources than the previous version.  “Telling” is now integrated throughout the entire toolkit to highlight the importance of communication at every step. The agency has also developed a helpful flushing best practices factsheet, which is a topic that often causes considerable confusion.

In EDF’s June 2018 report on our pilot of 11 child care facilities, “Tackling lead in water at child care facilities,” we recommended EPA update its 2006 guidance to address four key gaps.  The agency has made progress on the two most important of those but leaves the other two unresolved. The most important change to the guidance is that the agency has removed the 20 parts per billion (ppb) action level and instead recommends action whenever there are “elevated lead levels.” While EPA does not define an elevated lead level, a deep dive into the appendix suggests that levels over 5 ppb warrant follow-up. The updated guidance also puts a greater emphasis on the identification of lead service lines (LSLs) and includes LSL replacement as a permanent control measure, though not as an explicit recommendation. Further, the agency did not update the protocol to deal with challenges posed by aerator cleaning and hot water heaters.  Below we explore each of these issues in further detail. Read More »

Mapping state-level lead service line information: Indiana as a model

Lindsay McCormick, is a Project Manager. Tom Neltner, J.D., is the Chemicals Policy Director.

Developing inventories to document and share what water utilities know – and do not know – about lead service lines (LSLs) with the public is a difficult, but critical, step in creating an effective LSL replacement program.

States can play an important role in collecting estimates of the number of known and potential LSLs for each utility and shaping how that information is communicated to the public. 14 states have surveyed utilities operating community water systems in their state to acquire such information.

States have made this information publicly available through different methods. Some have posted individual utility reports, while others have provided a report summarizing the findings. In analyzing the approaches, we found that no state currently makes the results available in a format that allows the public to easily see the information from multiple utilities.

But in today’s world, people typically expect data to be presented in a visually friendly and digestible format. So as a model, we decided to create a state-level map of LSL information.

Of the 14 states, we found that Indiana has one of the most robust surveys, asking detailed questions about portions of the service line containing lead, information sources checked, and service line ownership on public versus private property.  Further, it has a good response rate for a voluntary survey. While only 57% of systems responded, these systems account for 92% of the LSLs in the state – as most non-respondents were primarily smaller community water systems.

EDF acquired a spreadsheet from the Indiana Department of Environmental Management and combined this information with data from EPA’s State Drinking Water Information System (SDWIS) to develop a map of LSLs in Indiana as a model.

Challenge to FDA’s GRAS rule moves forward after court rejects request for dismissal

Tom Neltner, J.D.is Chemicals Policy Director

In a critical ruling for food additive safety, a federal district court ruled on Wednesday that EDF, represented by Earthjustice, has standing in its legal challenge to the Food and Drug Administration’s (FDA) Generally Recognized as Safe (GRAS) rule. This 2016 final rule allows food manufacturers to make secret GRAS safety determinations for chemicals added to food, without notifying FDA or the public, and to use the chemical in food without anyone else’s knowledge. The court was considering a motion to dismiss from FDA arguing that plaintiffs did not have standing to bring the case. The judge found EDF and the Center for Food Safety (CFS) “plausibly allege harm to their members” and therefore “satisfy the injury-in-fact requirement for standing.” Our legal challenge now moves to the substance of our concerns with the flaws in the agency’s GRAS Rule.

The court found that members of EDF and CFS showed a risk of harm consistent with the requirements of the law in alleging that FDA’s “GRAS Rule poses a credible threat to their members.” Specifically the court stated that:

  • Their members “have been and will be exposed to potentially dangerous substances that were introduced into the food supply without FDA oversight, public participation, or the opportunity for judicial review.”
  • They “explicitly identify multiple substances that manufacturers determined to be GRAS and used in food despite concerns raised by FDA about their safety, as well as additional undisputedly dangerous substances that Plaintiffs reasonably anticipate will be introduced into the food supply under the GRAS Rule.”
  • “[T]hese injuries are ongoing and imminent.
