The New York Times reports that for the first time the FDA has allowed produce to be irradiated at levels needed to protect against illness causing one of the most significant food safety actions done for fresh produce in many years. Gardiner Harris writes,
The government will allow food producers to zap fresh spinach and iceberg lettuce with enough radiation to kill micro-organisms like E. coli and salmonella that for decades have caused widespread illness among consumers.
It is the first time the Food and Drug Administration has allowed any produce to be irradiated at levels needed to protect against illness.
“This is probably one of the single most significant food safety actions done for fresh produce in many years,” said Robert Brackett, chief scientist for the Grocery Manufacturers Association, which petitioned the agency in 2000 to allow manufacturers to irradiate a wide variety of processed meats, fruits and vegetables and prepared foods.
Advocates for food safety condemned the agency’s decision and asserted that irradiation could lower nutritional value, create unsafe chemicals and ruin taste.
“It’s a total cop-out,” said Patty Lovera, assistant director of Food and Water Watch. “They don’t have the resources, the authority or the political will to really protect consumers from unsafe food.”
Dr. Laura Tarantino, director of the Office of Food Additive Safety at the F.D.A., said the agency had found no serious nutritional or safety changes associated with irradiation of spinach or lettuce.
“These irradiated foods are not less safe than others,” Dr. Tarantino said, “and the doses are effective in reducing the level of disease-causing micro-organisms.”
The government has long allowed food processors to irradiate beef, eggs, poultry, oysters and spices, but the market for irradiated foods is tiny because the government also requires that these foods be labeled as irradiated, labels that scare away most consumers.
“People think the product is radioactive,” said Harlan Clemmons, president of Sadex, a food irradiation company based in Sioux City, Iowa.
The F.D.A. is considering a proposal to weaken or change this labeling requirement, a move that Caroline Smith DeWaal, food safety director at the Center for Science in the Public Interest, opposes.
Advocates of irradiation say the technology can help reduce the burden of illness and the number of outbreaks.
“Wegmans is fully committed to offering product that is safe to our customers,” said Jeanne Colleluori, a spokeswoman for Wegmans, a supermarket chain based in Rochester that is the only major retailer of irradiated beef. If irradiated spinach and lettuce become available, Wegmans will “offer it as a choice so that customers can try it,” Ms. Colleluori said.
Critics say that not only does radiation make food less nutritious and potentially toxic but that the process also does not eliminate the risks of food-borne illnesses. An analysis by the Centers for Science in the Public Interest found that most outbreaks of illnesses associated with salad are caused by viruses, which are not affected by the doses of radiation approved by the F.D.A.
Food-safety advocates, food producers and even farm groups agree that the government should mandate certain agricultural and processing practices that would limit the risk of all food-borne illnesses and increase the speed with which outbreaks are traced back to sources.
“The agency is choosing to have a high-tech expensive solution to a problem that needs a more thorough approach and one that really starts on the farm,” Ms. Smith DeWaal of the science center said.
Federal officials say they continue to study the science behind proposals to require good agricultural practices. In the meantime, irradiation could help, Dr. Tarantino of the F.D.A. said.
“This is not a magic bullet,” she said. “It’s not a solution for everything. It’s one more option that people can use.”
