Data and Reports

For Everyone

At a glance

  • NARMS reports and interactive data dashboards summarize antimicrobial resistance among enteric bacteria.
  • The reports and dashboards describe the number and type of isolates collected, their associated antimicrobial resistance, and trends in antimicrobial resistance.

Data

NARMS Now: Human Data

Part of NARMS Now data dashboard. A map shows resistance percentages by state. A line graph shows resistance percentages by year.
NARMS Now: Human Data makes it easier and quicker to find out how antimicrobial resistance has changed.

NARMS Now provides antimicrobial resistance data for five bacteria transmitted commonly through food and how they have changed over the past two decades.

NARMS Now: Integrated Data

Part of NARMS integrated data dashboard, showing isolates with no resistance detected in 2020 and 2019.
Integrated NARMS surveillance provides info needed to assess the nature and magnitude of resistance in bacteria moving through the food supply and causing illnesses in humans.

FDA's interactive, integrated data dashboards and summaries represent a consolidated view of resistance data generated from humans, animals, and retail meats.

Reports

Interim Data Updates

NARMS provides timely updates when testing reveals resistance to medically important antibiotics.

NARMS interim data updates summarize recent unusual or concerning antimicrobial resistance in enteric bacteria detected through NARMS surveillance.

Multi-year Report on Salmonella

Graph from FSIS NARMS multi-year report showing percentage of cattle, chicken, swine, and turkey samples positive for Salmonella.
The continuous tracking of Salmonella serotypes and resistance trends serves as an early indicator of potential threats to public health.

The USDA-FSIS NARMS multi-year report evaluates trends in Salmonella serotypes and antimicrobial resistance in certain food animal species and products from 2014 through 2019.

This report focuses on antimicrobial resistance trends and emerging threats in Salmonella serotypes of public health concern.

Antimicrobial Resistance Threats Report

Acetinobacter bacteria with text overlay: CDC's new AR Threats Report identifies 4 urgent, 13 serious, and 2 concerning threats, plus 6 watch list pathogens.
CDC's Threats Report provides info on antimicrobial resistance, the latest burden estimates, emerging areas of concern, and actions needed.

CDC's Antibiotic Resistance Threats Report provides the most comprehensive estimates of the impact of drug resistance on human health in the United States to date.

This report underscores the continued threat of antimicrobial resistance, the actions taken to combat this threat, and gaps slowing progress.
