Regulators have their work cut out in enforcing stricter U.S. food-safety rules set in motion this year, according to new data that show progress in reducing contamination has slowed from about six years ago.
Total cases of foodborne illness were unchanged last year from 2006-2008, stalling from “substantial declines” in earlier years, according to preliminary data released today by the Centers for Disease Control and Prevention. Some incidents increased, including a 43 percent jump in vibrio, a bacterial infection often acquired by eating raw oysters.
The Obama administration has been slow to fully enact the 2011 Food Safety Modernization Act, which was supposed to be the most sweeping overhaul of U.S. food safety in 70 years. The administration this year proposed the first major regulations, which Congress called for after poisonings related to cookie dough, spinach, jalapenos and other foods killed at least nine people and sickened more than 700 in 2008 and 2009.
“There’s not a lot of recent progress to talk about,” said Robert Tauxe, deputy director of the Atlanta-based CDC’s division of foodborne, waterborne and environmental diseases, in an interview. “That means there’s more that could be done.”
One of two regulatory proposals made Jan. 4 to carry out the core of the food safety act would give companies one year to develop a formal plan for preventing the causes of food illness. The second would force produce farms with a “high risk” of contamination to develop new hygiene, soil and temperature controls.
“Both of these are important and when they begin to be adopted, we hope that will help,” Tauxe said.
Neither proposal has taken effect, nor have any of the other major provisions of the food safety act. The Obama administration has said additional rules under the law are likely to be released later this year.
The CDC report showed there were 19,531 foodborne infections and 4,563 hospitalizations in 2012, with 68 deaths, based on surveillance data from laboratory-confirmed infections at 10 sites in the U.S. The sites are a representative sample that covers 15 percent of the population, or about 48 million people. Many cases of foodborne illness are never diagnosed by physicians.
Salmonella is still the most common foodborne infection even though incidents declined to 7,800 confirmed cases, the CDC said. The bacteria, commonly passed from the feces of chickens or other animals to contaminate water and produce, may lead to diarrhea, fever and abdominal cramps.
Campylobacter, a diarrhea-causing pathogen associated with poultry, raw milk and untreated water, rose 14 percent to the highest level since 2000. There were 6,793 campylobacter cases, and 2,138 for shigella, a condition that may lead to a severe infection in children less than 2 years old, the CDC said.
The U.S. Department of Agriculture set new standards in July 2011 for salmonella and campylobacter in young chickens and turkeys. Those rules set a percentage level of samples that can test positive for the pathogen, and within two years the USDA estimates about 5,000 campylobacter illnesses and 20,000 illnesses from salmonella will be prevented annually.
Preliminary results indicate the standards may be having an effect, said David Goldman, assistant administrator for the office of public health science at the USDA.
“The evidence we have, and it’s preliminary, is that campylobacter is decreasing on whole chickens and whole turkeys,” he said today on a conference call.
The incidence of all foodborne infections last year were highest among children younger than age 5, according to the report. Deaths and hospitalizations were highest among seniors 65 and older.
The percentage of victims who died was highest among those 65 and older who were infected with vibrio, at 6 percent, and salmonella, at 2 percent, according to the report. The percentage of patients who died from all pathogens studied was highest for listeria, at 11 percent.
