Over 7 million children exceed FDA’s new daily maximum intake level of lead

Tom Neltner, Senior Director, Safer Chemicals

This is the fourth in our Unleaded Juice blog series exploring how the Food and Drug Administration (FDA) sets limits for toxic elements like lead, arsenic, and cadmium in food and the implications for the agency’s Closer To Zero program.

In June, after issuing its proposed action levels for lead in juice, FDA tightened its Interim Reference Levels (IRLs) for lead to 2.2 µg/day for children and 8.8 µg/day for females of childbearing age—a drop of 27% from the original IRLs it established in 2018. We estimate this change increased the number of children over the IRL for lead from 1.2 million to more than 7 million.

The agency describes IRLs as daily maximum intake levels for lead in food and beverages. FDA scientists said the change was made to match the Centers for Disease Control and Prevention’s (CDC) October 2021 revised blood lead reference value.  This value is commonly known as the elevated blood lead level (EBLL).[1] FDA uses the “interim” label in recognition that there is no known safe level of exposure to lead and the neurotoxic harm it can cause. FDA anticipates matching the IRLs to future reductions in CDC’s reference value as the U.S. makes progress in reducing children’s exposure to lead.

We applaud FDA’s decision to tighten the IRLs. It is a good example of the type of continuous improvement to which FDA committed in its Closer to Zero Action Plan, which aims to lower levels of lead, cadmium, mercury, and inorganic arsenic in food that babies and young children eat and drink.

The challenge now is to translate the tighter daily maximum intake level into action levels for specific foods. Next steps for FDA should include:

  • Further tightening its recently proposed action level for lead in juice.
  • Using the revised lead IRLs as:
    • The basis for its proposal for foods commonly consumed by babies and young children – currently stuck in the review process at the White House’s Office of Management and Budget (OMB).
    • A model for FDA’s anticipated IRLs for inorganic arsenic and cadmium under its Closer to Zero program.

Tara Flour: A Reminder of the Real-Life Consequences of Broken GRAS

Tom Neltner, Senior Director, Safer Chemicals and Maricel Maffini, EDF consultant

This blog is the fifth in our Broken GRAS series where we explore the Food and Drug Administration’s (FDA) Generally Recognized as Safe (GRAS) system for novel chemicals added to food.

In the spring, folks who ordered from a company that sells pre-assembled smoothies and other frozen foods for home delivery, started getting sick—really sick—after consuming an item called “French Lentil and Leek Crumbles” (Crumbles). Daily Harvest, the manufacturer, recalled the product on June 17. A month later, Daily Harvest said it had ruled out various food-borne pathogens, mycotoxins, heavy metals, and major allergens and had “identified tara flour as the cause of the issue.”

By the end of July, FDA reported the product had been linked to 329 illnesses and 113 hospitalizations in 36 states—a surprising number for a product that sold only 28,000 items. Consumer Reports described the health effects as fever, fatigue, vomiting, diarrhea, and liver problems. At least 25 people who consumed the Crumbles required surgery to remove their gallbladders.

Unleaded Juice: Getting Credible Lab Results is Essential

Tom Neltner, Senior Director, Safer Chemicals

This is the third in our Unleaded Juice blog series exploring how the Food and Drug Administration (FDA) sets limits for toxic elements like lead, arsenic, and cadmium in food and the implications for the agency’s Closer To Zero program.

FDA’s move to establish action levels on lead in juice – and eventually other foods that young children eat or drink – is an important step forward. While we believe that the action levels need to be tougher, any action level has a limited value if labs that analyze samples for contamination provide results that buyers, regulators, or consumers cannot trust.

We recommend that labs meet four criteria to provide credible results:

  • Be accredited under international standards for testing and calibration of labs (ISO/IEC 17025);
  • Use the analytical method based on FDA’s Method 4.7 [PDF, 1.16MB];
  • Demonstrate proficiency in a third-party, blinded test to quantify lead, arsenic, and cadmium to around 6 parts per billion (ppb); and
  • Provide a written report of results at that level.

Here is the list of labs that met these criteria as of August 2021. See below for our in-depth analysis.

Broken GRAS: It’s time for FDA to wake up and protect consumers from dubious ingredients

Maricel Maffini, consultant and Tom Neltner, Chemicals Policy Director

This blog is the third in our Broken GRAS series where we explore how the Food and Drug Administration’s Generally Recognized as Safe (GRAS) voluntary notification system for novel chemicals added to food works in practice and why it is broken.

In this blog, we examine another voluntary GRAS notice submitted to the FDA, this one for Venetron, an extract of Apocynum venetum leaves. It is marketed for sleep improvement and anti-stress and used as a dietary supplement and food ingredient. Documents obtained through a Freedom of Information Act (FOIA) request reveal that FDA scientists raised safety concerns about Venetron. Under the broken GRAS system, however, the company that manufactures the ingredient was able to withdraw its notification and continue to market the chemical as GRAS, despite the questions raised by the agency.

____

Japanese company Tokiwa Phytochemical (Tokiwa) voluntarily notified the Food and Drug Administration (FDA) in August 2014 that it had determined its extract of Apocynum venetum leaves was Generally Recognized as Safe (GRAS). The extract, called Venetron, would be an “ingredient in food” at levels up to 100 mg per day, the company said in the notice (GRN 530). Tokiwa indicated that Venetron could be incorporated into “health food product[s], such as tablet[s] or capsule[s],” but did not identify specific foods to which the substance might be added.

In support of its GRAS determination, the company presented results of preclinical and clinical investigations that examined the safety of the extract in mice and healthy adult male volunteers. They also reported data on the effectiveness of Venetron to treat individuals with mild depression. It convened a panel of three experts ‒ Drs. Veronika Butterweck (Univ. of Applied Sciences and Arts, Northwestern Switzerland), Sansei Nishibe (Health Sciences Univ. of Hokkaido), and Kuo-Hsiung Lee (Univ. North Carolina at Chapel Hill) ‒ to review the studies, as well as a “history of human intake” of Rafuma [another name for A. venetum] leaf extract and its use as a dietary supplement in Japan and as a drug in China to treat insomnia, kidney disease, hypertension and heart palpitations.

Tokiwa said the panel “unanimously concluded that VENETRON™, when used in foods in general at levels providing a daily total intake of 100mg/person/day, is safe,” and that the GRAS determination was based on “scientific procedures supported by a history of safe use.” Read More »

Broken GRAS: Scientists’ safety concerns are hampered by FDA’s inactions on food chemicals

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

A federal district court this fall ruled that the Food and Drug Administration (FDA) has the authority to allow food companies to make Generally Recognized as Safe (GRAS) safety determinations for novel chemicals added to food without notifying the agency. The decision followed a lawsuit by EDF and others, in which we challenged this practice. The court agreed, in part, with FDA that an uptick in companies voluntarily choosing to send notices to the agency since the 2016 rule went in effect was a sign that the program was working.  We disagree with the court’s conclusion but opted not to appeal.

This blog is the second in our Broken GRAS series where we explore how the voluntary notification system works in practice and why it is broken. The first dealt with a synthetic chemical called apoaequorin and marketed as Prevagen, a chemical found in jellyfish and used in protein shakes. The company claims the substance helps memory, but FDA has repeatedly raised serious questions about its safety. Despite the agency’s concerns the company continues to sell the product as GRAS. 

In this blog, we examine another voluntary GRAS notice, this one for GABA, a neurotransmitter naturally produced in the brain and known to slow down certain nervous system activities. It is marketed as a food ingredient despite FDA’s serious concerns with the notice that prompted the company to withdraw it. The agency does not make such information publicly available. We were able to learn of FDA’s concerns through a Freedom of Information Act (FOIA).

____

Companies have the option to voluntarily notify FDA when they determine that a use of a new chemical or a new use of an existing chemical is Generally Recognized as Safe, or GRAS. When they do notify FDA, agency scientists then review the data and supporting information and can ask additional questions. In most of the cases, FDA agrees with the company’s determination and publishes a “no questions” letter. In roughly 20% of cases, however, companies ask the agency to stop the process after receiving the scientists’ questions. FDA then stops its review and announces a “cease to evaluate” status in the GRAS notification inventory, and that’s the end of it. There is no public record of as to why the company withdrew the notice. In some cases, a brief summary is included in the agency’s response to the cease to evaluate letter published in its website. The company is free to market and sell the substance if it still believes the chemical’s use is GRAS.

This happened with gamma aminobutyric acid (GABA). As you will see, the GABA case is a prime example of the 1) importance of FDA’s scientific review of safety data, and 2) profound implications for health risks when the agency takes no action in response to safety concerns raised by its own experts. A product with the safety concerns we describe below warrants closer examination, regardless of its current market share. Where serious health effects are found, it is important for FDA to act quickly before a specialty product like this one becomes more popular, and its health risks amplified. Read More »

Broken GRAS: Undermining the safety of dietary supplements and food

Tom Neltner, Chemicals Policy Director and Maricel Maffini, consultant

Over the years, we have seen a disturbing approach being taken by some dietary supplement companies to circumvent the Food and Drug Administration’s (FDA) oversight. Their strategy undermines both dietary supplement safety and food safety. These companies are leveraging FDA’s decision to allow manufacturers to secretly self-certify food chemicals as Generally Recognized as Safe (GRAS) in order to:

  1. Bypass mandatory new dietary supplement ingredient (NDI) notice requirements; and
  2. Expand their market from dietary supplements into conventional food.

We have long-challenged FDA’s interpretation of the GRAS exemption in the Food Additives Amendment of 1958 because it results in the agency being unable to fulfill its statutory duty to ensure food is safe.[1] When Congress passed the amendment, the GRAS exemption was expected to be for common substances like oils and vinegar. In this blog, we explain how the agency’s flawed approach to GRAS also undermines the safety of dietary supplements. Read More »
