No Real Progress on Food Poisoning
Media reports covering the latest CDC data on food poisoning have focused on a slight decline in the incidence of E. coli O157:H7 infections in 2009.
But the bottom line of the report is that no real progress has been made in six years in reducing dangerous pathogens in our food.
"The interventions begun in the late 1990s were successful in decreasing some of these foodborne diseases, but we haven’t seen much recent progress,” said Chris Braden, M.D., acting director of CDC’s Division of Foodborne, Waterborne, and Environmental Diseases. “To make additional strides against these diseases and ultimately better protect the American people from foodborne illness, CDC, our federal and state partners, and the food industry will need to try new strategies."
Braden was commenting on annual CDC surveillance data released this week by FoodNet, a food poisoning detection and reporting system operated by CDC in collaboration from 10 state health departments, USDA and FDA. It tracks E. coli O157:H7, Salmonella, Listeria, Campylobacter, Shigellaand four other pathogens.
For most of the infections, the rate was highest in children under the age of 4 years. People over 50 years old had the highest rates of hospitalizations and deaths from most foodborne illnesses, emphasizing the need for those over 50 to get diagnosed and get treatment quickly after becoming ill.
Among the four pathogens tracked in FoodNet that have national incidence goals, Salmonella is furthest from meeting the goal. According to CDC, there is slow progress in fighting Salmonella because it is spread through a wide variety of foods, and also through non foodborne routes. Salmonella can be spread by poultry, meat, eggs, produce and processed foods, as well as by contact with animals like baby chicks, small turtles, reptiles and frogs.
Shigella and E. coli O157:H7 were the two pathogens that experienced lower incidence rates in 2009 when compared to 2006-2008. The Healthy People goal for E. coli was a rate of less than 1 infection per 100,000 people. The 2009 ratio was .57 per 100,000, down 25 percent. For Shigella, the incidence rate was down 27 percent to 3.99 per 100,000.
