Americans didn't suffer more food poisoning last year despite high-profile outbreaks involving peppers, peanut butter and other foods, according to a government report released today.
Rates of food-borne illnesses have been holding steady for four years. They had been declining from the mid-1990s until the beginning of this decade, due mainly to improvements in the meat and poultry industry, some experts say.
But produce-associated food poisonings have been increasing, and the nation is no longer making progress against food-borne disease rates, said Elliot Ryser, a professor of food science at Michigan State University.
"I was not surprised," Ryser said, referring to the new report from the U.S. Centers for Disease Control and Prevention.
The report looks at the occurrence of ten leading food-borne illnesses in ten states that participate in a federally-funded food poisoning monitoring system. CDC officials believe it's nationally representative, based on the sample's mix of geography and demographics.
The research appears in this week's issue of a CDC publication, Morbidity and Mortality Weekly Report.
Salmonella remained the most common cause of food poisoning, causing more than 7,400 lab-confirmed illnesses in those states. That translates to a rate of about 16 cases for every 100,000 people. Most experts say those numbers are lower than reality, however, because only a fraction of food poisoning cases get reported or confirmed by laboratories.
Campylobacter and shigella, two kinds of bacterial infections, were the second and third most common food-borne illnesses, occurring at rates of about 13 and 7 per 100,000, respectively.
The researchers don't address how many people died.
An estimated 87 million cases of food-borne illness occur in the United States each year, including 371,000 hospitalizations and 5,700 deaths, according to an Associated Press calculation that used the CDC formula and current population estimates.
There were geographic variations in disease rates among the states, the CDC found. The highest rates of salmonella occurred in Georgia and New Mexico, campylobacter was most common in California and E. coli thrived best in Colorado.
Those variations were no doubt influenced by some specific outbreaks that caused more illnesses in some states than others, Ryser said.
Prominent food-borne illness outbreaks in 2008 included:
_A salmonella outbreak linked to hot peppers and tomatoes from Mexico that sickened more 1,400 Americans. It was the nation's largest outbreak of food-borne illness in a decade, and was first identified in New Mexico and Texas.
_A peanut-related salmonella outbreak _ which started last year _ caused at least 690 confirmed illnesses in 46 states and was linked to nine deaths.
_A salmonella outbreak attributed to Honduran cantaloupes sickened 51 people in 16 states.
Better testing and surveillance has improved the government's ability to detect food-borne disease outbreaks, Ryser said.
Outbreaks account for just a fraction of cases in the ten states last year, however. For example, only 7 percent of the salmonella cases were tied to identified outbreaks, the CDC report said.
