A report published by the Centers for Disease Control and Prevention (CDC) in the US has suggested that there was little change in the rate of incidences of foodborne infections in 2007.

The CDC conducted the research as part of its Foodborne Diseases Active Surveillance Network, FoodNet. It said the 10-state report, which examined data from 2007, showed little change in the incidence of some foodborne infections following a period of decline.

According to the research, rates of Campylobacter, Listeria, Salmonella, Shigella, E.coli O157, Vibrio, and Yersinia infection did not decline significantly, while the estimated incidence of Cryptosporidium increased when compared with the three years from 2004 to 2006. Although there have been significant declines in the incidence of some foodborne infections since surveillance began in 1996, these declines all occurred before 2004, the CDC stated.

“The results show that prevention efforts have been partly successful, but there has been little further progress in the most recent years,” said Dr Robert Tauxe, deputy director of CDC’s Division of Foodborne, Bacterial and Mycotic Diseases. “More needs to be done to make our food safer. We are constantly working to help our public health system better detect, investigate and control outbreaks and to understand how to prevent foodborne illnesses from happening in the first place. FoodNet is an important part of our food safety system and is how we measure progress.”

While the FoodNet constituency is similar to the US population, the CDC pointed out that the findings are used to detect trends and should not be generalised for the entire US population.
