“FoodCORE has greatly enhanced our case interviewing capacity. Before FoodCORE, we didn’t have resources to routinely interview people with Salmonella infections. During 2014-2015, FoodCORE-funded staff successfully interviewed over 2300 reported cases. This program is critical to our responding to suspected outbreaks.”

Program Highlight

South Carolina-FoodCORE enhances detection, investigation, and control of foodborne disease with increased staffing at the regional and central office levels to support laboratory and investigative expertise. Before funding, resources were not available for activities including 1) routine interview of people with a foodborne illness, 2) expanded food complaint surveillance, and 3) DNA fingerprint testing (PFGE) of all Salmonella isolates. These processes support the identification and rapid investigation of suspected outbreaks by epidemiologists.

Expanded food complaint surveillance plays a pivotal role in outbreak detection. It has expanded dramatically since FoodCORE funded a staff person dedicated to enhanced environmental health outbreak response. The proportion of food complainants interviewed (with interviews including a 72-hour food history) has risen from approximately 16% before funding to 76% in 2015.

Percentage of Food Complaints Successfully Interviewed by Year, South Carolina 2010-2015

Percentage of Food Complaints Successfully Interviewed by Year, South Carolina, 2010-2015. Data%26mdash;2010: 16%, 2011: 42%, 2012: 60%, 2013: 60%, 2014: 71%, 2015: 76. This figure shows a bar graph that compares the percentage of foodborne complaints that were successfully interviewed in South Carolina from 2009 - 2015. The height of each bar on the graph represents the percentage of complaints that were successfully reached for an interview. The percentage of successful interviews dramatically increased from 2010 to 2011 and has continued to steadily increase. In 2010, only 16% of complaints were successfully reached for an interview. In 2011, 42% of complaints were interviewed. In 2012 and 2013, 60% were interviewed. In 2014, 71% were interviewed. And most recently in 2015, 76% were interviewed.
