Reduce infections caused by Salmonella — FS‑04 Data Methodology and Measurement

About the National Data


Baseline: 15.3 laboratory-diagnosed, domestically-acquired Salmonella infections per 100,000 population occurred on average annually in 2016-18

Target: 11.5 per 100,000

Number of laboratory-diagnosed, domestically-acquired Salmonella infections in humans reported to FoodNet.
Number of persons in FoodNet surveillance area.
Target-setting method

Maintain consistency with national programs, regulations, policies, or laws

Target-setting method details
Target-setting method justification
The target was selected to align with the regulation "New Performance Standards for Salmonella and Campylobacter in Not-Ready-to-Eat Comminuted Chicken and Turkey Products and Raw Chicken Parts and Changes to Related Agency Verification Procedures: Response to Comments and Announcement of Implementation Schedule" (Federal Register 81 FR 7285 February 11, 2016, pages 7285-7300), which used a target-setting method of modeling.


Methodology notes

FoodNet conducts active population-based surveillance in 10 U.S. states for all laboratory-diagnosed infections with select enteric pathogens transmitted commonly through food. Campylobacter, Listeria, Salmonella, Shiga toxin-producing Escherichia coli (STEC) O157 and non-O157, Shigella, Vibrio, and Yersinia infections are diagnosed by laboratory testing of samples from patients. FoodNet personnel regularly contact clinical laboratories to ascertain laboratory-diagnosed cases of infection occurring within the surveillance sites. Hospitalizations occurring within 7 days of specimen collection date are recorded, as is the patient's status at hospital discharge or 7 days after the specimen collection date if not hospitalized. Deaths and hospitalizations are attributed to the pathogen if they occur within 7 days of the specimen collection date regardless of actual cause. International travel occurring within 7 days before illness onset is recorded. The pathogen is considered domestically-acquired if no travel occurred within 7 days before illness onset regardless of actual cause.


Comparable HP2020 objective
Modified, which includes core objectives that are continuing from Healthy People 2020 but underwent a change in measurement.
Changes between HP2020 and HP2030
This objective differs from Healthy People 2020 objective FS-1.4 in that objective FS-1.4 tracked the number of culture-confirmed cases of Salmonella infections, while this objective tracks domestically acquired Salmonella infections, both culture-confirmed and those identified through culture-independent diagnostic tests (CIDTs).
Revision History

In 2021, the original baseline was revised from 14.8 to 15.3 due to a data update that changed the baseline years from 2015-2017 to 2016-2018. The target was adjusted from 11.1 to 11.5 to reflect the revised baseline using the original target-setting method.
