At an FDA-sponsored conference, EDF proposed a new path forward to ensure innovative food ingredients are safe by overhauling how food additives are regulated today.

[/pullquote]Every day brings reports of new ingredients that food innovators around the world have developed to meet consumer demands for a healthier and more sustainable food supply. The innovations range from new ways to extract useful additives from existing sources such as algae to bioengineering to make novel ingredients like sweeteners or proteins that can be grown in a tank instead of on a farm.

At EDF, we encourage innovation that helps communities and the environment thrive, especially in the face of the threats posed by climate change. However, an innovator’s bold claims, especially those involving food safety, must be closely scrutinized before the additive hits the marketplace. Given the potential for harm to consumers, we cannot simply take a company’s assertion of safety at face value – there must be transparency and the Food and Drug Administration (FDA) must provide an independent review.

EDF joins court challenge of FDA’s refusal to ban use of perchlorate in food contact materials

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: October 29, 2019

Today, EDF, represented by Earthjustice, joined with other public health advocates in filing a lawsuit to overturn the Food and Drug Administration’s (FDA) May 2017 decision, reaffirmed in April 2019 that allows the continued use of perchlorate[1], at concentrations up to 12,000 parts per million, in plastic packaging and processing equipment in contact with dry food. Perchlorate exposure is particularly dangerous for fetuses, infants, and young children, as it has been linked to developmental delays, reduced growth, and impaired learning capabilities. FDA relied on flawed reasoning while entirely ignoring important evidence developed by its own scientists revealing potentially serious risks resulting from ongoing use of perchlorate. We maintain that the intentional and unnecessary use of perchlorate in food contact materials should end.[2]

As with any litigation, we take this action reluctantly. We have long questioned FDA’s decisions that ignore evidence that endocrine disruptors like perchlorate can cause harm at levels the agency systematically dismisses as trivial. We have also pushed back on FDA’s decisions that allow toxic chemicals to be used in packaging and processing equipment that contact food ingredients multiple times from the farm to the grocery store shelf when the exposure estimate is based solely on the amount of the chemical that may migrate into food from the final product packaging. Agency assertions that its estimates are based on worst-case assumptions are misleading when they only consider a single contact. While FDA’s initial decision in November 2005 allowing the use of perchlorate-containing plastic raises all of these problems, the agency’s failure to address its own data and accompanying analysis by its own scientists that was published a decade later has left us with little choice but to act.

Latest federal data on lead in food suggests progress made in 2016 was fleeting

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: October 3, 2019

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

The Food and Drug Administration’s (FDA) Total Diet Study (TDS) is an important source of data for both the agency and the public to estimate exposure, track trends, and set priorities for chemical contaminants in food. EDF analyzed TDS data for samples the agency collected from 2003-2013 in our 2017 report to reveal that lead in food was a hidden health threat. In follow-up blogs using TDS data from 2014-2016, we reported that overall trends for detectable rates of lead appeared to be on the decline, especially in 2016. In our analysis, we summarized that the trends were both good news and bad news for children because there were stubbornly high rates of detectable lead in baby food teething biscuits, arrowroot cookies, carrots, and sweet potatoes.

In this blog, we analyze the latest lead in food TDS data, released by FDA in August, and we take a new look at the trends. Overall, the 2017 data reversed the progress in 2016, largely driven by the percent of samples[1] with detectable lead in prepared meals nearly doubling from 19% to 39%. The good news is that fruit juices continued their dramatic and steady drop in samples with detectable lead, from 67% in 2016 to 11% in 2017. When we compared results for baby foods to similar samples of regular fruits and vegetables, the most notable finding was that baby carrots and peeled and boiled carrots had significantly lower detection rates than baby food carrot puree. Additionally, we were surprised to find that 83 of 84 samples of canned fruit had detectable levels of lead.

Where are Illinois’ lead pipes? Chicago Water has nearly 60%, and small systems don’t know.

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: September 25, 2019

Tom Neltner, J.D., Chemicals Policy Director and Lindsay McCormick, Program Manager.

Chicago is the epicenter for lead service lines (LSLs) in the United States. In a report submitted to Illinois Environmental Protection Agency (IEPA) in April, Chicago Water reported having 392,614 LSLs – 75% of the total service lines in its water system that serves 2.7 million people living in the city and the city’s 125 suburbs. The number of LSLs is over three times higher than any other city. For additional context, this number represents 58% of the known LSLs in Illinois and 6% of the estimated 6.1 million LSLs in the country.

Chicago Water also reported an additional 120,760 service lines as unknown material that may be lead. Only 7,299 (2%) of its total service lines are made of something other than lead.

These numbers are based on the second year of mandatory reporting that IEPA makes publicly available. Earlier this year, we summarized the first year of reporting. In the second year of reporting, IEPA improved the program by allowing CWSs to separately report lines of unknown material where the utility was confident they were not LSLs – most likely because the lines were installed after the date the CWS stopped allowing use of lead. So the remaining lines of “unknown material” were more likely to be lead. In addition, all community water systems (CWSs) in the state reported in the second year.[1] Given these improvements, we looked more closely at the data.

Lead from new “lead-free” brass faucets? An update on progress

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: August 21, 2019

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

[Update: On 10/23/19, the NSF committee responsible for revising NSF 61 tentatively agreed to tighten the limits on lead leaching from new faucets and drinking fountains. The committee will move forward with a formal vote and, if approved, will receive public comment on the proposed changes.]

Last year, we discovered and reported in a blog, that some new brass faucets that meet existing standards and are labelled “lead-free” can still leach significant amounts of lead into water in the first few weeks of use. Here, we answer some questions that have come up and provide an update on efforts to revise the NSF/ANSI 61 standard to better protect and inform consumers.

Last November, the committee responsible for revising the NSF/ANSI 61 standard convened a group to consider an optional certification for faucets that meet a more protective limit. A study of more than 500 models of faucets showed that 73% of faucets leach less lead into water and can meet a limit that is five times more protective for children. However, currently there is no easy way to identify these “lower lead” models. The optional certification would enable consumers, schools, and child care facilities to identify and purchase faucets that leach less lead to drinking water.

Unfortunately, as described later in this blog, representatives of the brass faucet manufacturers have worked to block the optional certification. As of August 2019, the committee has not decided whether to move forward with a proposal for the optional certification to receive public notice and comment. If the committee fails to move forward, we anticipate that some major retailers that sell brass faucets and other major buyers such as school districts and builders would use their leverage to set higher standards in their purchasing specification that favors models performing better on the NSF/ANSI 61 lead leaching test.

Chemours asks FDA to suspend its approved uses of PFAS in food packaging

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: August 9, 2019

Tom Neltner, J.D., Chemicals Policy Director

Politico reported today that Chemours notified the Food and Drug Administration (FDA) that it had officially abandoned its three approved food packaging uses of per- and poly-fluorinated alkyl substances (PFAS) and asked the agency to withdraw its Food Contact Substance Notifications (FCNs) for those uses. We do not know with certainty what prompted Chemours to abandon its PFAS products for food packaging or whether they were ever used in the United States. Based on past experience, we anticipate that FDA will grant the request.

This action takes us one step closer to reducing people’s exposure to these chemicals linked to an array of health risks posed by PFAS at extremely low levels. Additionally, the action should serve as an incentive for other companies to do the same.

Chemours also has FCNs for six PFAS uses in repeat-use food contact articles like gaskets and seals. The company apparently has not asked the agency to abandon these uses. We suspect that the PFAS-treated gaskets may still be in service even if it has stopped treating new gaskets with the chemicals.
