NEW YORK -- Campbell Soup says it supports a mandatory national labeling standard for products containing genetically modified ingredients.
The maker of Pepperidge Farm cookies, Prego sauces and Spaghetti-Os says it will withdraw its support from various groups and coalitions opposing such labeling, which has become a contested issue in recent years. The move marks a break from industry groups that have sought to make labeling voluntary.
About three-quarters of Campbell's products contain GMOs. The company says it opposes a patchwork of state by state legislation that it believes would confuse customers.
States have tried to address the issue on their own and Vermont passed legislation requiring food makers to disclose when certain products contain genetically modified ingredients by July. But industry groups want to pre-empt such efforts with federal legislation that would make disclosures voluntary, said Michele Simon, a public health lawyer.
"They're going for as little as they can," Simon said.
If a federal labeling standard isn't established in a "reasonable amount of time," Campbell says it will work independently to disclose the presence of GMOs in its products. The company did not specify a timeline for doing so.
Genetically modified seeds are engineered in laboratories to have certain traits, like resistance to herbicides. The majority of the country's corn and soybean crop is now genetically modified, with much of that going to animal feed. Corn and soybeans are also made into popular processed food ingredients like high-fructose corn syrup, corn starch and soybean oil.
The food industry says about 75 percent to 80 percent of foods contain genetically modified ingredients. The Food and Drug Administration has said that the GMOs are safe.
Still, the number of products stamped with a voluntary "non-GMO" label from a third-party group has proliferated as the issue has gained more attention. The label, which is more prominently displayed on the front of packages, has become a marketing tool in some cases.
PepsiCo, for instance, has said it will start labeling some of Tropicana juices as "non-GMO," even though genetically modified oranges do not exist.
Campbell Soup CEO Denise Morrison has been outspoken about the need for big food makers to adapt to changing tastes. The company, based in Camden, New Jersey, has been diversifying its packaged food lineup with offerings that are seen as fresher. Its acquisitions in recent years include premium juice and carrot seller Bolthouse Farms and Plum Organics, which makes baby food.
