Responding to Consumer Concern, Campbell's Goes BPA-Free


Responding to Consumer Concern, Campbell’s Goes BPA-Free

BPABack in September, the traditionally family-friendly Campbell’s Soup brand was attracting attention from moms for all the wrong reasons: A report released by advocacy group Breast Cancer Fund found the company’s soup to have some of the highest BPA levels among a variety of canned foods it tested. Of particular concern to parents was the fact that the products most appealing to children–soups and Spaghetti-O’s with fun shapes in them–ranked highest in the study. BPA (bisphenol A), a commonly used additive in food packaging, mimics human estrogen and is thought by some health advocates to be harmful to health, while others maintain that it is perfectly safe. At the time, Campbell Soup Company spokesman Anthony Sanzio said the company was confident in the safety of its products. ”The overwhelming weight of scientific evidence shows that the use of BPA in can lining poses no threat to human health,” he said. “That being said, we understand that consumers may have concerns about it. We’re very aware of the debate and we’re watching it intently.”

A month later, a study from the Harvard School of Public Health, published in the journal Pediatrics, linked exposure to BPA during pregnancy to hyperactive, depressive, and anxious behavior in young girls, finding that the higher the mothers’ BPA levels, the more likely the girls were to exhibit behavior problems as toddlers. Meanwhile, several states, including California, moved forward with bans on the use of BPA in children’s products. The American Chemistry Council, a trade group with members that use BPA, denounced the Harvard study as having “significant shortcomings” and drawing “conclusions of unknown relevance to public health,” and called concern over BPA in children’s products unnecessary, stating that BPA is rarely used in such products anymore. The statement seemed surprising given the lengths to which the group had gone to fight legislation on BPA in children’s products in California and other states. Steven Hentges, of ACC’s polycarbonate/BPA global group, told the New York Times that even though baby bottles and sippy cups no longer contain BPA, the trade group had good reason to oppose the California legislation as well as other state and federal initiatives banning BPA, saying that it should be the Food and Drug Administration, and its team of scientists, making regulatory decisions, not state legislators.

Now Hentges may be getting his wish. The FDA announced earlier this month its intention to reevaluate the safety of BPA in packaging, promising a decision on the matter by March 31, 2012. That announcement was prompted by a petition filed by the Natural Resources Defense Council (NRDC) back in 2008. In the meantime, French lawmakers voted in late February to uphold a ban on the use of BPA in all packaged foods. That law is likely to lead to E.U.-wide legislation on the matter, which would make it financially untenable for U.S. food manufacturers that sell into Europe to continue using BPA, irrespective of U.S. legislation.

To date, the FDA has maintained that BPA does not pose a health threat at the low levels at which it appears in canned and packaged foods. Several researchers and public health advocates, however, have argued that the average load a person consumes is far more than the levels set for any one product, and that the chemical has negative effects even at very low levels. Others argue that the FDA’s average daily exposure estimates are way off. According to independent studies conducted by Consumer Reports in 2009, “Consumers eating just one serving of the canned vegetable soup we tested would get about double what the FDA now considers typical average dietary daily exposure.” [Progresso, Campbell's, and Del Monte products had the highest BPA levels of the products tested.]

Anticipating not only a potential FDA change on BPA, but also continued consumer backlash, Campbell’s announced today its plan to phase out the use of the chemical in its can linings. Although the company has not announced a specific timeline, or released any further details of its BPA-free commitment, at a February shareholders meeting, Campbell’s Chief Financial Officer Craig Owens reported that the shift to BPA-free cans had already begun, and would not impose a significant cost to the company.

We believe that current can packaging is one of the safest options in the world; however, we recognize that there is some debate over the use of BPA,” he said. “The trust that we have earned from our consumers for over 140 years is paramount to us and we have been monitoring and working on the issue for several years. Because of this, we have already started using alternatives to BPA in some of our soup packaging and we are working to phase out the use of BPA in the lining of all of our canned products. The cost of this effort is not expected to be material.”

Canned soup linked to elevated levels of BPA

Canned soup linked to elevated levels of BPA

Eating canned soup may be convenient, but it can significantly raise the level of bisphenol A in a consumer’s body, according to a new study from the Harvard School of Public Health.

Bisphenol A, better known as BPA, is an odorless, tasteless chemical used in the linings in almost all canned food and drinks, and it is also found in many hard plastic bottles.

Growing evidence suggests that low levels of BPA may be harmful to the development of fetuses and young children.

The Harvard study found that people who consumed a serving of canned soup each day for five days had BPA levels more than 10 times higher in their urine then after they ate fresh soup daily for five days.

“We suspect the increased levels we saw was a temporary increase in BPA, though we can’t say how long it would persist,” said Jenny Carwile, a Harvard doctoral candidate and the study’s lead author.

BPA prevents food and beverage cans from rusting, and increases the shelf-life of canned products. But other studies have found that the chemical can leach from the lining into the contents, regardless of the product’s age or how it is stored.

The Harvard study, published online today in the Journal of the American Medical Association, measured BPA levels in the urine of 75 volunteer students and staff at Harvard, and is one of the first to quantify the levels after people ingested canned food.

One group of volunteers ate a 12-ounce serving of vegetarian canned soup at lunch each day for five days, while another group consumed 12 ounces of vegetarian soup that was prepared without canned ingredients for five days.

After a two-day ‘washout’ period, the groups reversed their assignments. Participants were not restricted in their consumption of any other foods.

Urine samples, taken between 3 p.m. and 6 p.m. on the fourth and fifth day of each phase of the study, found that a serving of canned soup daily was associated with a 1,221 percent increase in BPA compared with levels in urine collected after the volunteers ate freshly-prepared soup.

“A lot of people will say, They ate it at lunch and peed it out so we don’t have to worry about it,” but we don’t know what damage it’s doing in the few hours that it’s there,” said Laura N. Vandenberg, a postdoctoral fellow in Tufts University’s biology department who has done research on BPA, and was not involved in the Harvard study.

Vandenberg said that while the study involved only 75 people, it suggests that large spikes in BPA levels after consuming canned food may not be uncommon.

Another study published earlier this year by researchers at the Silent Spring Institute in Massachusetts found that BPA levels were substantially reduced among five families when canned food and items packaged in plastic were removed from their diets for three days.

The families’ BPA levels returned to their pre-study levels when they resumed their normal diets.

Vandenberg said other studies have found significant variation in the amounts of BPA detected in canned foods made by the same company.

“It varies from one can to the next, and from one food to the next,” she said. “You have no idea if the canned food you are eating is full of it, or not.”

Massachusetts in 2009 warned parents of young children to avoid storing infant formula or breast milk in plastic bottles containing BPA, and also urged pregnant or breast-feeding women to avoid the chemical in other food and drink containers.

But some scientists and advocates say Massachusetts has not gone far enough because studies since then have continued to link health problems to BPA. They have requested that BPA be removed from products typically used by pregnant women and young children. Some states, such as Connecticut, have banned the chemical in infant formula and baby food products, and in a range of reusable food and drink containers.
