CDC says overall rate of foodborne infections remains the same in 2014

While some diseases decreased in 2014, the Centers for Disease Control says overall rate of infections from foodborne illness remains the same

The Centers for Disease Control in its yearly update on foodborne illness, released last week, said the 2014 data for foodborne infections shows that some instances of diseases have decreased while the overall rate of foodborne infections remains the same.

2014 foodborne illness instances
In 2014, rates of infection from a serious form of E. coli and one of the more common Salmonella serotypes decreased compared with the baseline period of 2006-2008. Meanwhile, some other less common types of Salmonella increased.

Campylobacter and Vibrio rose again in 2014, continuing the increase observed during the past few years.

Infection with Shiga-toxin producing E. coli O157 decreased 32% when compared with 2006-2008 and 19% when compared with the most recent three years. These infections are often linked to consumption of undercooked ground beef and raw leafy vegetables.

Salmonella Typhimurium, which has been linked to poultry, beef, and other foods, was 27% lower than it was in 2006-2008, continuing a downward trend begun in the mid-1980s.

Two other less common types of Salmonella, Javiana and Infantis, more than doubled for reasons that are unclear. Salmonella Javiana is concentrated in the southeastern United States, but has been spreading within the Southeast and to other areas of the country. However, when all Salmonella serotypes are combined, there was no change in 2014.

Campylobacter increased 13% and Vibrio increased 52% compared with 2006-2008. Yersinia has declined enough to meet the Healthy People 2020 goal.

What was counted
The data are from FoodNet, CDC's active surveillance system that tracks nine common foodborne pathogens in 10 states and monitors trends in foodborne illness in about 15% of the U.S. population.

CDC's report compares the 2014 frequency of infection with the frequency in the baseline period 2006-2008 and in the three most recent years.

Overall in 2014, FoodNet logged just over 19,000 infections, about 4,400 hospitalizations, and 71 deaths from the nine foodborne germs it tracks. Salmonella and Campylobacter were by far the most common – accounting for about 14,000 of the 19,000 infections reported.

"We're cautiously optimistic that changes in food safety practice are having an impact in decreasing E.coli and we know that without all the food safety work to fight Salmonella that more people would be getting sick with Salmonella than we are seeing now," Robert Tauxe, M.D., deputy director of CDC's Division of Foodborne Waterborne and Environmental Diseases said in a statement.

"The increasing use of whole genome sequencing to track foodborne illness cases will also help; however, much more needs to be done to protect people from foodborne illness," he said.

The E. coli decline
The recent decline in the incidence of Shiga toxin-producing E. coli O157 follows several years of increasing scrutiny for beef products. Since 1994, the USDA Food Safety and Inspection Service has taken STEC O157:H7 seriously and has made a number of changes in its regulatory oversight of the beef industry to protect public health.

"We are encouraged by the reduction of STEC O157:H7 illnesses, which reflects our science-based approach to beef inspection, and we look forward to seeing further reductions in Salmonella and Campylobacter infections as our improved standards for poultry take effect later this year, " Al Almanza, Deputy Under Secretary for Food Safety at USDA said in a statement.

Under the provisions of the FDA Food Safety Modernization Act, the U.S. Food and Drug Administration is planning to publish major new regulations in 2015. The regulations are geared toward ensuring produce safety, implementing preventive controls on processed foods, and improving the safety of imported foods.
