Prevent an increase in the proportion of macrolide antibiotic-resistant Campylobacter infections — FS‑06 Data Methodology and Measurement

About the National Data


Baseline: 2.0 percent of domestically-acquired Campylobacter jejuni infections in humans were resistant to macrolides in 2016-18

Target: 2.0 percent

Number of domestically-acquired Campylobacter jejuni infections in humans resistant to macrolides.
Number of domestically-acquired Campylobacter jejuni infections in humans tested for resistance to macrolides.
Target-setting method
Maintain the baseline
Target-setting method justification
Maintaining the baseline is the preferred target because, by reducing the overall incidence of infections and limiting the prevalence of resistance (maintaining the current level), a reduction in the incidence of antimicrobial resistant infections can be achieved.


Methodology notes

Public health laboratories in 10 FoodNet sites forward a frequency-based sample of Campylobacter isolates that they receive from participating clinical/reference laboratories to NARMS at CDC. CDC scientists test isolates for susceptibility to macrolides and other drug classes using a broth microdilution method and interpret results using criteria from the Clinical and Laboratory Standards Institute (CLSI) when available. Domestically-acquired infections (i.e., no international travel in the 7 days before illness onset) will be identified using travel information available from FoodNet.


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-3.6 in that objective FS-3.6 tracked Campylobacter jejuni infections that were resistant to erythomycin, while this objective tracks domestically-acquired Camplyobacter jejuni infections that are resistant to macrolide antibiotics.
Revision History

In 2023, the baseline and target were changed from 2.5 in 2014-2016 to 2.0 in 2016-2018 to align the baseline year range with the other Food Safety Topic Area objectives.
