Meetings and Publications

Since its inception, NARMS has continued to expand and improve. Regular inter-agency meetings have been held, as well as periodic reviews from outside experts, to identify areas for improvement. The most recent meetings are listed below.

October 24-25, 2017 - The Food and Drug Administration, together with the NARMS partner agencies, will conduct a public meeting entitled “2017 Scientific Meeting of the National Antimicrobial Resistance Monitoring System.” The purpose of this meeting will be to summarize NARMS progress since its last public meeting, to present recommendations made by the recent FDA Science Board review of NARMS in 2017, and to explore new directions for NARMS within a One Health paradigm. Items that will be discussed during this meeting include an update on the development of new analytical and reporting tools, the latest advances in the use of DNA sequencing technologies, and new surveillance results.

June 26, 2017 – An external subcommittee was invited to review the NARMS program in 2017 and the results of their review were presented to the FDA Science Board Committee on June 26, 2017. The charge to the review committee was to provide recommendations regarding sampling strategies within a One Health paradigm, reporting antimicrobial sales and resistance data, and suitable ways to report whole genome sequence data and trends in the resistome. The recommendations were also presented at the 2017 Scientific Meeting of the National Antimicrobial Resistance System.

August 12-13, 2014 - The Food and Drug Administration (FDA) will conduct a public meeting entitled ‘‘2014 Scientific Meeting of the National Antimicrobial Resistance Monitoring System.’’ The purpose of this meeting will be to provide updates on progress of the NARMS 2012-2016 strategic plan, discuss possible future activities and receive comments for the official record. A number of items will be discussed including comparisons of new and old slaughter sampling methods, the role of NARMS in foodborne outbreaks, results of interagency research projects using advanced detection methods, and finally how these scientific advances impact FDA decision making.

December 4-6, 2013 - Representatives from the three participating NARMS agencies (FDA, CDC, USDA) met in Atlanta, Georgia to 1) review progress on the goals and objectives outlined in the NARMS 2012-2016 Strategic Plan and devise next steps; 2) explore ways that NARMS could build on the 2012-2016 Strategic Plan to address other public health needs and fill data gaps; and 3) discuss the potential impact of new laboratory advances on NARMS and determine a plan of action.

September 10-11, 2012 - NARMS held a Retail Meat Meeting in Silver Spring, Maryland. This year marks the 10th anniversary of the retail meat testing component of NARMS. This event brought together epidemiologists and microbiologists from the 14 states that participate in the NARMS Retail Meat Surveillance Program, along with representatives from the CDC, USDA, and the Canadian Integrated Program for Antimicrobial Resistance Surveillance (CIPARS). The goal of this meeting was to reflect on the successes and lessons learned from the past 10 years of retail meat surveillance and to plan and prioritize future work on NARMS.

July 20, 2011 - A public meeting was held in St. Louis, Missouri. The purpose of the meeting was to explore different animal and retail sampling strategies in an effort to modify the existing NARMS sampling scheme.

July 15-16, 2010 – A public meeting was held in Atlanta, Georgia. This meeting focused on activities in various national monitoring programs, ongoing research, and stakeholder perspectives on NARMS.

August 5-7, 2009 – NARMS partners attended a second meeting in Rockville, Maryland to report on progress, and to begin formalizing a Strategic Plan.

September 10-12, 2008 - NARMS partners held an inter-agency planning meeting in Athens, Georgia. This meeting was held to prioritize activities to address the Science Board subcommittee recommendations, and to implement measures to address them.

April 10, 2007 - An FDA Science Board subcommittee reviewed the NARMS program and made recommendations related to four areas of work: 1) sampling, 2) research, 3) international activities, and 4) data management and reporting. Included in the report was a recommendation to develop a long-range strategic plan.

June 23-24, 2005 - CVM met with outside experts in Rockville, Maryland to obtain individual authoritative opinions on key elements and future directions of the NARMS program.
