FoodCORE Center: Ohio

map of the state of Ohio

Program Overview

The Ohio Department of Health (ODH) provides technical assistance to 119 local health departments (LHD). With FoodCORE funding, ODH established centralized interviewing and increased laboratory testing of bacterial isolates, which improved the state’s capacity to respond to foodborne outbreaks.

“My health department has been participating in the FoodCORE program since 2012. We give it our highest recommendation. The student interview team at ODH eases the persistent problems of staffing shortages and overworked communicable disease nurses at the local health department.”

Program Highlight

Centralized interviewing of Salmonella, Shiga toxin-producing E. coli, and Listeria (SSL) patients started in June 2012. Ohio-FoodCORE has four student interviewers who contact all individuals with SSL infections reported from local health departments participating in FoodCORE. Timely and complete interviews are important for identifying potential outbreaks and associated causes.

Ohio increased the capacity for conducting DNA fingerprinting using pulsed-field gel electrophoresis (PFGE). Before FoodCORE, less than 50% of the Salmonella isolates received underwent PFGE analysis. From 2009 through 2015, the Ohio Department of Health Laboratory increased the number of Salmonella isolates subtyped by PFGE each year from 702 to over 1,400 isolates. Additionally, the average turn-around time for Salmonella PFGE decreased from 6.5 to 2 days. As a result, more PFGE matched Salmonella clusters are being investigated at an earlier stage.

Salmonella PFGE Turn-Around Time (Receipt to PulseNet Upload)

Salmonella PFGE Turn-Around Time (Receipt to PulseNet Upload), Ohio, 2009-2015. Data—2009: 6.5Days, 2010: 3.5 Days, 2011: 2.5 Days, 2012: 2 Days, 2013: 2 Days, 2014: 2 Days, 2015: 2 Days. This figure shows a line graph that displays the median number of days from receipt of an isolate to uploading the PFGE results to PulseNet at the Ohio FoodCORE lab from 2009 to 2015. The line drops drastically from 2009 to 2010 and continues to decrease to a plateau of 2 days beginning in 2012. In 2009, the turnaround time was 6.5 days. In 2010, it dropped to 3.5 days. In 2011, turnaround time was 2.5 days. In 2012, it dropped further to 2 days and has remained at 2 days through 2015.
