FDA’s latest study reaffirms short-chain PFAS biopersist. Now it must act.

FDA study found biopersistent PFAS in female rats and their pups,

What Happened

In December 2023, FDA’s scientists published a new study showing that when pregnant rats ingest a form of per- and polyfluorinated alkyl substance (PFAS) called 6:2 fluorotelomer alcohol (6:2 FTOH) their bodies break it down into other PFAS that reach the fetuses and biopersist in the mother and the pups.

The study also showed that the body of a non-pregnant animal produces different breakdown products that also biopersist. This study is the latest evidence that the assumptions made about the safety of short-chain PFAS (chemicals with fewer than 8 carbons) have been wrong. Read More »

FDA’s approach to systematic review of chemicals got off on the wrong foot

What Happened?

Last month, FDA’s scientists published the toxicological reference value (TRV) for exposure to cadmium in the diet. This value is the amount of a chemical—in this case cadmium—a person can consume in their daily diet that would not be expected to cause adverse health effects and can be used for food safety decision-making. The TRV was based on a systematic review FDA scientists published last year. We will turn to the TRV itself in an upcoming blog but are focusing on the systematic review here.

In a May 2023 publication, experts in systematic reviews from the University of California San Francisco (UCSF) raised concerns about FDA’s “lack of compliance” from established procedures.

We discussed these concerns with FDA. They said:

  • “The systematic review and the TRV” publication “have both undergone external peer review by a third-party and experts in the field.” The agency expects to publish the reviews on its website, and
  • FDA “is working on developing a protocol for a systematic review of cardiovascular effects of cadmium exposure that will be published.”

Why It Matters

Systematic review is a method designed to collect and synthesize scientific evidence on specific questions to increase transparency and objectivity and provide conclusions that are more reliable and of higher confidence than traditional literature reviews. In particular, the National Academies of Sciences, Engineering, and Medicine have recommended the use of systematic reviews to establish values such as the TRV that may be used to inform regulatory decisions.

The National Toxicology Program (NTP) and others have developed specific methodologies to conduct systematic reviews. FDA’s authors said they followed NTP’s Office of Health Assessment and Translation (OHAT) handbook.

Unfortunately, FDA’s adherence to the methodology fell short on both transparency and objectivity grounds, undermining the credibility of its conclusions. Credibility is crucial because FDA’s authors stated that “this systematic review ultimately supports regulatory decisions and FDA initiatives, such as Closer to Zero, which identifies actions the agency will take to reduce exposures to contaminants like cadmium through foods.”

California mandates toxics testing/disclosure for baby food

What Happened?

On October 10, 2023, California Assembly Bill 899, authored by Assembly Member Al Muratsuchi, became law. It requires manufacturers of baby food (other than infant formula) who wish to sell their products in California to:

  • Test a representative sample of each baby food product for four toxic elements (arsenic, cadmium, lead, and mercury) at least monthly starting in 2024.
  • Provide the test results to the California Department of Health upon request.
  • Make the results of the testing publicly available on the manufacturer’s website for the shelf life of the product plus one month. That provision goes into effect in 2025.

In addition, as FDA establishes action levels for the four toxic elements, manufacturers must also include a quick response (QR) code on the label that links to the manufacturer’s website, where consumers can find the test results for that toxic element.

Why It Matters

By requiring testing and reporting on these foods, California will provide parents and guardians with important information they need to compare products and make purchasing decisions. The law also:

  • Sets a precedent for greater testing and disclosure of food contaminants; and,
  • Is noteworthy, in that baby food companies did not oppose the bill.

The law will strengthen FDA’s efforts to reduce children’s dietary exposure to those toxic elements to the lowest possible levels, while maintaining access to nutritious foods by filling two critical gaps in FDA’s Closer to Zero program. FDA current approach sets action levels on final products that food companies must meet and requires they use preventive controls to manage toxic elements in their ingredients. It does not require final product testing or disclosure of any testing results.

Anti-androgenic chemicals as a class of related substances with cumulative toxicological effects

Maricel Maffini, consultant, and Tom Neltner, Chemicals Policy Director

Scientists and regulators have known for decades that certain chemicals disrupt the actions of male hormones—identified collectively as androgens—in the body. Because of their effects, these chemicals are called anti-androgens or anti-androgenic chemicals.

During gestation, fetal testes begin producing testosterone, the critical hormone required to develop reproductive organs and genitalia. Insufficient production of testosterone leads to malformation of the genital tract that may need corrective surgery in infant boys and may result in reproductive health problems later in life. Ortho-phthalates (aka phthalates), known to interfere with the production of fetal testosterone, are considered anti-androgenic chemicals.

Although phthalates are perhaps the most recognizable group of anti-androgenic chemicals in the diet, there are others, including bisphenol A (BPA), propyl paraben, and certain pesticides used in food crops. Because they cause similar harmful effects, namely adverse health outcomes for male reproductive system, their safety assessment must take into account the cumulative effects of similar substances in the diet as established by law. But what does “cumulative effect” mean? Below, we use a recent study to explain what it means, why it is important, and why FDA is failing.

FDA decisions leave ortho-phthalates in food and our safety in limbo

Tom Neltner, Senior Director, Safer Chemicals; Maricel Maffini, Ph.D., Consultant

On May 19, the Food and Drug Administration (FDA) announced four incongruous actions in response to petitions submitted by EDF and others asking the agency to ban the use of more than two dozen ortho-phthalates (phthalates) in food packaging and processing equipment. We filed the petitions because we were concerned that these hormone-disrupting chemicals were harming people, especially children, who consume food contaminated by this class of chemicals. Since filing the petitions six years ago, the evidence of harm – and our concern for children’s health – have only grown more compelling.

Despite a statutory duty to decide whether the authorized uses were safe, the agency delayed making a decision and then essentially dodged the safety issue, opting instead to allow nine phthalates it had approved decades ago to be used in plastics, paper, and adhesives that contact food or drinks. FDA only acted in response to a lawsuit filed by Earthjustice for EDF and other health and environmental advocates.

FDA’s decisions allow phthalates to continue to seep into our food and do little to protect the public. As a result, EDF and the other advocates, supported by Earthjustice, filed formal objections to the agency’s decisions on two food additive petitions and petitioned the agency to reconsider its denial of a separate citizen petition. We also demanded an evidentiary public hearing to consider the significant new evidence FDA glossed over. Read More »
