A closer look at FDA’s “Closer to Zero” plan to reduce for heavy metals in children’s food

This month, the Food and Drug Administration (FDA) released its “Closer to Zero” action plan to reduce exposure to heavy metals in foods for babies and young children. The plan, released in response to a recent House of Representatives Committee on Oversight and Reform report and the introduction of the Baby Food Safety Act in both the House and the Senate, is a step forward since it commits the agency to specific actions and general deadlines for the first time. However, there is room for improvement, specifically the agency should:

  1. Explicitly consider the cumulative effect of heavy metals on neurodevelopment when setting limits.
  2. Move up deadlines for draft action levels for arsenic and cadmium;
  3. Be consistent in messaging that there is no safe level of lead in children’s blood;
  4. Define what “as low as possible” and “children’s food” means as soon as possible;
  5. Be transparent by posting testing data quickly; and
  6. Add milestones for compliance verification with action levels and preventive controls.

House Oversight Committee draws renewed attention to heavy metals in baby food and calls for FDA to act

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: February 11, 2021

Tom Neltner, J.D. is the Chemicals Policy Director.

Last week, the House Committee on Oversight and Reform’s Subcommittee on Economic and Consumer Policy released an important report summarizing baby food testing data submitted by four companies (Beech-Nut, Gerber, Happy Family, and Earth’s Best), finding that “baby foods are tainted with dangerous levels of arsenic, lead, cadmium and mercury.” These heavy metals are widely recognized as harming children’s brain development.

The report found that three of the four companies (all but Gerber) used ingredients that had exceeded limits set in their internal standards. Additionally, the committee cited “grave concerns” that three other companies (Walmart, Plum, and Sprout) did not provide their internal standards and testing results in response to the legitimate request by the House Committee. Their lack of transparency undermines credibility and trust.

Due to the alarming nature of these findings about a food marketed as safe and healthy for infants and toddlers, the report garnered significant attention and has prompted calls for the Food and Drug Administration (FDA) and food manufacturers to do more on this issue.

Importantly, the report provides new insights into industry decision-making processes, highlights the need for greater oversight, and adds urgency to EDF’s ongoing efforts to reduce heavy metals in food.

Best practices for reducing cadmium in food: New review from FDA scientists

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: April 7, 2020

Note to readers: As we all grapple with the grave global health challenge from COVID19, we want to acknowledge the essential services that the professionals at the Food and Drug Administration and in the food production, processing and retail industries provide in continuing to deliver food. In the meantime, we are continuing to work towards improved health protections – including reducing chemicals in food. We’ll plan to keep sharing developments that may be useful to you. In the meantime, please stay safe and healthy.

Two years ago, the Food and Drug Administration (FDA) put cadmium on our radar when the Toxic Elements Working Group included cadmium together with arsenic, lead and mercury as metals affecting children’s neurological development. As part of that effort, FDA committed to look at all four metals across all foods instead of one contaminant, one food at a time. Last year, FDA’s scientists published a peer-reviewed article assessing children’s exposure to lead and cadmium in the diet. They found that spinach, lettuce, sunflower seeds, potato chips and wheat cereal were among the top 10 foods with the highest cadmium concentration.

New review of mitigation strategies

This year, FDA’s scientists published in a peer-reviewed journal a review of mitigation strategies to reduce dietary exposure to cadmium. Because plants uptake cadmium from the soil and “70 to 80% of dietary cadmium intake in humans comes from plant-based food,” the article focuses on methods to “reduce or prevent initial uptake by plants.” The authors explained that cadmium enters the food supply through natural and manmade sources, highlighting that cadmium often is a contaminant in phosphate fertilizers. Cadmium is also a contaminant in zinc used to galvanize steel.

When it comes to testing heavy metals in food, the result is only as good as the lab.

“Even though the levels 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.”

 

Dr. Conrad Choiniere, leader of FDA’s Toxic Elements Workgroup on April 20, 2018

[/pullquote]

Heavy metals such as arsenic, cadmium, and lead are present in most foods, whether conventional or organic, usually as the result of environmental contamination. Because heavy metals pose significant threats even at low levels, the Food and Drug Administration (FDA) has made reducing cumulative exposure a priority. The Baby Food Council – consisting of Beech-Nut Nutrition Company, Happy Family Organics, Earth’s Best, and Gerber Products Company and supported by Healthy Babies Bright Futures (HBBF), Cornell University and EDF – shares this goal and seeks to reduce heavy metals in the companies’ products to as low as reasonably achievable using best-in-class management practices.

Through the Council, EDF is coordinating a proficiency testing program to enable retailers, food manufacturers, ingredient suppliers, and others to identify laboratories that are capable of measuring arsenic, cadmium, and lead at levels in the low parts per billion (ppb). The Council has arranged for FAPAS, a leading proficiency testing provider for the food and water testing industries, to manage the testing program.

Too much cadmium and lead in kids’ food according to estimates by FDA

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: May 7, 2019

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

The Food and Drug Administration (FDA) released a study in April estimating young children’s exposure to lead and cadmium from their diets and identifying food groups that are a significant source of these heavy metals. The study used data from the agency’s Total Diet Study (TDS) program for 2014 to 2016 and the Center for Disease Control and Prevention’s (CDC) What We Eat in America (WWEIA) Survey for 2009 to 2014.[1]

The study is a reminder of how pervasive heavy metals are in children’s diets and that, while the levels are relatively low, the cumulative exposure is significant. Based on FDA’s analysis (Table 1 below), we estimate that about 2.2 million children exceeded the agency’s maximum daily intake (MDI) for lead at a given time. The results for cadmium are new and worrisome, with estimated daily intake (EDI) levels that are 3 to 4 times greater than lead. And while FDA has not yet set an MDI limit for cadmium, the average young child exceeds most of the relevant daily exposure limits set by other agencies. Clearly, cadmium warrants greater attention, but note that the evidence of neurotoxicity is still emerging.

For children’s food, heavy metals require more attention and better standards

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: June 12, 2018

In June 2017, EDF released Lead in Food: A Hidden Health Threat. The report examined a decade’s worth of data from the Food and Drug Administration (FDA) and found lead detected in 20% of baby food samples compared to 14% for other foods. Eight types of baby foods, including fruit juices, root vegetables, and teething biscuits, had detectable lead in more than 40% of the samples. We closed the report with the following recommendation:

In the meantime, parents should consult with their pediatrician to learn about how to reduce lead exposure. They should also check with their favorite brands and ask whether the company regularly tests their products for lead, and ensures that, especially for baby food, there is less than 1 ppb of lead in the food and juices they sell.

As described below, we have reason to believe it will take more focused effort on the part of both FDA and food companies to ensure consistently low levels of heavy metals – lead, arsenic, and cadmium in particular – in infant’s and toddler’s diets.
