Rich Liroff on BPA: Better safe than sorry

Today’s guest post is from Richard A. Liroff, Ph.D., the founder and director of the Investor Environmental Health Network (IEHN), a group of investors and NGO that advocates for safer corporate chemicals policies to reduce financial and reputational risk to companies, and grow long-term shareholder value. That’s a mouthful, but in essence, Rich and his allies try to persuade companies to use safer chemicals; you can find a list of shareholder resolutions on safer chemicals policies at the IEHN website, www.iehn.org.

A lifelong environmentalist, Rich has worked on toxic issues of various kinds since the late 1980s, when he looked at indoor air quality. “That work exposed me to the idea that air pollution hazards from toxics might be greater indoors than outdoors,” he told me. He formed IEHN in 2004 and says: “I thought the best way to move the issue forward was by working with the private sector.” Since then, of course, we’ve heard a lot about chemicals in products ranging from household cleaners to toys to cosmetics. This article is about BPA, which has interested me since I wrote a long story for cnnmoney.com called Wal-Mart: the new FDA in 2008. I worried then that the BPA controversy was more about emotion and entrenched interests (on both sides) than it was about science. I’m not sure things have improved much, but you can be the judge of that. Rich’s column originally appeared at Greenbiz.

On January 15, 2010, The U.S. Food and Drug Administration (FDA) shifted its position on the safety of the chemical Bisphenol A (BPA), expressing for the first time some concern about safety, announcing further research, and providing tips for parents to minimize infants’ exposure.

As a result, smart companies will change the way they communicate about BPA and as well as search for alternatives to better align themselves with consumer concerns. Some companies could gain reputational benefits and free media attention from supporting proposed legislation restricting use of BPA.

Major users of BPA in the U.S. and Canada already have exited the market for polycarbonate baby bottles and cups containing BPA. Others are pursuing strategies to reduce reliance on BPA for lining food containers. Replacing food can linings is technically tougher, because of the need to satisfy numerous food safety, durability, and other requirements.

No company can say they didn’t see this coming. Since the late 1990s a growing body of evidence has linked BPA to a broad array of health effects, particularly due to exposures to low doses of BPA during critical windows of development.

In 2008, two market-shaking events occurred. Health Canada, Canada’s overseer of food, drug, and product safety, announced in April that it intended to ban the import, sale and advertising of polycarbonate baby bottles containing BPA because of concerns about the health impact of low dose exposure. In September 2008, the U.S. National Toxicology Program (NTP), headquartered at the National Institute of Environmental Health Sciences (NIEHS) stated in its final report on the developmental effects of BPA exposure that it had “some concern” for effects on the brain, behavior, and prostate gland in fetuses, infants, and children at current levels of human exposure. These two announcements effectively shut down the market for polycarbonate baby bottles in the U.S., as major retailers said they would stop selling them and manufacturers sought alternatives.

There was a similar movement away from polycarbonate sport bottles, such as those sold by Nalgene and Camelbak. As detailed in an Investor Environmental Health Network (IEHN) report, the winners in the marketplace were those who saw the science changing and were prepared to make a shift. Whole Foods Market had made the move two years earlier, having become aware of the accumulating science and having been further encouraged to act by a shareholder resolution. By contrast, Sigg took a reputational hit for being less than open about its use of BPA.

In 2009, the BPA controversy intensifed. New scientific studies were published, with independent academic studies raising continuing concerns while some large scientific studies funded by industry dismissed them. Questions were raised as to whether industry lobbyists had inappropriate behind the scenes access to FDA staff and whether FDA staff was giving undue weight to industry studies as they assessed whether FDA’s existing standard for BPA was sufficiently protective. Using funds from the economic stimulus package, NIEHS, a unit of the National Institutes of Health, awarded $30 million in research grants to further study the health effects of BPA.

Politically, major battles were fought in in state and local legislatures. Minnesota’s ban on BPA in baby bottles and cups took effect on January 1, 2010. Connecticut’s legislation, which takes effect in October 2011, bans BPA in containers for infant formula and baby food, and for all reusable food and beverage containers. Chicago and Suffolk County, New York have also enacted bans on BPA in baby bottles and sippy cups. In the U.S. Congress, in March 2009, Senator Dianne Feinstein and Representative Edward Markey introduced the Ban Poisonous Additives (BPA) Act of 2009, whose title describes its purpose. In battling these legislative initiatives, the American Chemistry Council and industry allies relied on FDA’s position and similar determinations from Europe to argue that BPA is safe.

Remarkably, market and regulatory changes in North America have moved faster than in Europe. This is a noteworthy exception to the customary pattern in recent years of the European Union phasing out chemicals and then major U.S. companies, California and other states, and occasionally the U.S. government, following Europe’s lead.

In the marketplace, finding “drop-in” substitutes for BPA has been relatively easy for baby bottles and cups. The larger technical challenge has been finding replacements for epoxy resins containing BPA that are used as can linings. Eden Foods in the U.S. uses non-BPA linings for its packaging, except for acidic foods. While these cans cost 14 percent more than BPA-lined cans, the cost differential might decrease if more food processing companies were to determine that this alternative satisfies their own technical specifications, and higher production volumes achieved greater economies of scale.

Likewise, while Japanese can manufacturers successfully reduced BPA exposures there beginning in the 1990s, for their alternative approach to take root in the United States would also require satisfying manufacturers’ and food processors’ functionality requirements here.

Last April, two participants in IEHN, Green Century Capital Management and the As You Sow Foundation, reported the results of a survey of 20 publicly-owned food processors on their use of BPA and search for alternatives in packaging. Top scores were awarded to Hain Celestial, Heinz, and Nestle for their work on exploring alternatives; the report noted that Heinz was the only respondent already using a substitute to BPA in some of its can linings.

There’s clearly a rich prize to be reaped by the partnership of lining formulators and container manufacturers who are the first across the finish line with a safer, technically feasible, and economically competitive alternative to BPA linings that serves all or most of the needs of major food processors.

The most important part of FDA’s January 15th policy shift was the agency’s aligning itself with the U.S. National Toxicology Program’s scientific judgment about BPA. FDA said that standardized toxicity tests had thus far supported the safety of BPA but “on the basis of results from recent studies using novel approaches to test for subtle effects, both the National Toxicology Program … and FDA have some concern about the potential effects of BPA on the brain, behavior, and prostate gland in fetuses, infants, and young children.”

Environmental health groups lauded FDA’s position shift, though they expressed regret that FDA did not act immediately to tighten regulation and voiced support for the pending congressional BPA Act. The American Chemistry Council said it was “disappointed that some of the recommendations [to parents] are likely to worry consumers and are not well-founded.” ACC also noted, pointedly, that “The HHS statement today confirms that exposure to BPA in food contact products has not been proven harmful to children or adults.”

Companies relying on the existing FDA standard for BPA can no longer confidently use it as a shield, now that the agency has  acknowledged uncertainty and expressed support for BPA exposure reduction. Instead, they need to be more forthcoming about their search for alternatives, aligning themselves with customers concerned about involuntary exposures to a toxic chemical that could compromise the health of their children. Companies should look to Whole Foods Markets’ website discussion as a model.

Indeed, smart companies should seek to turn the worries over BPA into a competitive advantage. They can raise their visibility and improve their reputation by supporting legislation that bans BPA bottles and cups. Downstream users such as retailers are better served by adopting a “better safe than sorry” position—at least for cases of easy replacement—rather than taking a more defensive “harm hasn’t been proven” stance.

Comments

  1. The various research done on BPA does prove one thing: that continuous exposure to it can be harmful to health. So it is better to make sure that all plastic products one uses are BPA free.

    Nowadays, one can easily find products like BPA free water and milk bottles, baby bottles, lunch boxes, containers, products for ones microwave, freezer or refrigerator, and even BPA free toys. So protect your health and that of your near and dear ones by using only BPA free products.
