Highlights

Antibiotics have saved millions of lives, but antibiotic use in food animals contributes to the emergence of resistant bacteria that may affect humans. The Departments of Health and Human Services (HHS) and Agriculture (USDA) are primarily responsible for ensuring food safety. GAO reviewed the issue in 2004 and recommended improved data collection and risk assessment. GAO was asked to examine the (1) extent to which agencies have collected data on antibiotic use and resistance in animals, (2) actions HHS's Food and Drug Administration (FDA) took to mitigate the risk of antibiotic resistance in humans as a result of use in animals, (3) extent to which agencies have researched alternatives to current use practices and educated producers and veterinarians about appropriate use, and (4) actions the European Union (EU) and an EU member country, Denmark, have taken to regulate use in animals and lessons that have been learned. GAO analyzed documents, interviewed officials from national organizations, and visited producers in five states and Denmark..

Recommendations for Executive Action

Agency Affected Recommendation Status
Department of Agriculture 1. To track the effectiveness of policies to curb antibiotic resistance, including FDA's voluntary strategy designed to reduce antibiotic use in food animals and to address action items in the surveillance focus area of the 2001 interagency plan, the Secretaries of Agriculture and Health and Human Services should direct agencies to, consistent with their existing authorities, (1) identify potential approaches for collecting detailed data on antibiotic use in food animals, including the species in which antibiotics are used and the purpose for their use, as well as the costs, time frames, and potential trade-offs associated with each approach; (2) collaborate with industry to select the best approach; (3) seek any resources necessary to implement the approach; and (4) use the data to assess the effectiveness of policies to curb antibiotic resistance.
Closed - Not Implemented
In March 2017, we reported that HHS and USDA had made several improvements in collecting data on antibiotic use in food animals and resistance in bacteria. For example, in 2016, USDA's Animal and Plant Health Inspection Service developed study designs for two proposed on-farm surveys for antibiotic use on cattle feedlots and at swine operations. However, the agency had not collected data because, according to USDA, additional funding had not been secured. In addition, we reported in 2017 that HHS and USDA were conducting individual data collection efforts without a joint plan or selection of the best approach for collecting data despite holding a HHS and USDA public meeting in 2015 to gather input on possible approaches, thus risking inefficient use of their limited resources. HHS and USDA have also not used such data to assess the effectiveness of policies to curb antibiotic resistance which would fully address the recommendation.
Department of Agriculture 2. To better focus future federal research efforts on alternatives to current antibiotic use practices, the Secretaries of Agriculture and Health and Human Services should direct agencies to (1) assess previous research efforts on alternatives and identify gaps where additional research is needed, in collaboration with the animal production industry, and (2) specify steps in the draft 2010 interagency plan that agencies will take to fill those gaps.
Closed - Not Implemented
The Department of Agriculture's Agricultural Research Service (ARS) conducted efforts to assess gaps in research on alternatives to antibiotic use in food animals. For example, to assess gaps in research, the agency participated in a May 2012 Antibiotic Resistance Workshop. ARS also meets regularly with other agencies as part of the Transatlantic Task Force on Antimicrobial Resistance (TATFAR), which aims to identify gaps in antibiotic research. In the most recent 2014 TATFAR progress report, the group summarized the progress and the outcomes of the implementation of 17 recommendations. The next meeting is scheduled for October 2015. In March 2015, the White House issued the National Action Plan for Combating Antibiotic-Resistant Bacteria, superseding the 2010 interagency plan. ARS officials stated that the agency is working on implementing steps to address gaps in research on antibiotic alternatives as outlined in the White House's National Action Plan. The plan identifies various future milestones with timeframes from one to five years to identify and close these gaps so actions may not occur in the near future.
Department of Health and Human Services 3. To track the effectiveness of policies to curb antibiotic resistance, including FDA's voluntary strategy designed to reduce antibiotic use in food animals and to address action items in the surveillance focus area of the 2001 interagency plan, the Secretaries of Agriculture and Health and Human Services should direct agencies to, consistent with their existing authorities, (1) identify potential approaches for collecting detailed data on antibiotic use in food animals, including the species in which antibiotics are used and the purpose for their use, as well as the costs, time frames, and potential trade-offs associated with each approach; (2) collaborate with industry to select the best approach; (3) seek any resources necessary to implement the approach; and (4) use the data to assess the effectiveness of policies to curb antibiotic resistance.

In March 2017, we reported that HHS and USDA had made several improvements in collecting data on antibiotic use in food animals and resistance in bacteria. For example, in May 2016, HHS' Food and Drug Administration (FDA) finalized a rule requiring drug companies to report species-specific data, improving FDA's understanding of how antibiotics are sold and distributed for use in food animals. Additionally, in August 2016, FDA entered into two cooperative agreements with researchers for antibiotic use and resistance data collection to gather information on which antimicrobials are being used, for what disease indications, and at what dose and duration they are being used. In August 2017, HHS officials told us that the agency has been working in collaboration with USDA on other data collection approaches as well as the animal producer and veterinary groups, consumer advocate groups, and other stakeholders on the development of useful and appropriate metrics related to antibiotic use and stewardship. According to officials, while these efforts are still ongoing, significant progress has been made, despite limited resources, to enhance collection of data on antimicrobial use and to develop approaches for assessing the effectiveness of efforts to foster antimicrobial stewardship in food-producing animals. However, we reported in 2017 that HHS and USDA are individually collecting data without a joint plan or selection of the best approach for collecting data despite holding a HHS and USDA public meeting in 2015 to gather input on possible approaches, thus risking inefficient use of their limited resources. HHS and USDA have also not used such data to assess the effectiveness of policies to curb antibiotic resistance which would fully address the recommendation.
Department of Health and Human Services 4. To enhance surveillance of antibiotic-resistant bacteria in food animals, we recommend that the Secretaries of Agriculture and Health and Human Services direct agencies to, consistent with their existing authorities, modify the National Antimicrobial Resistance Monitoring System (NARMS) sampling to make the data more representative of antibiotic resistance in food animals and retail meat throughout the United States.
Closed - Implemented
The Department of Agriculture's Food Safety and Inspection Service (FSIS) worked with the Department of Health and Human Services' Food and Drug Administration (FDA) to make several improvements to NARMS. Specifically, according to FDA and FSIS officials, in March 2013, FDA and FSIS implemented a randomized, nationally representative sampling scheme to gather food animal samples for NARMS from slaughter plants, based on slaughter volume. In addition, FDA officials said that in January 2013 FDA expanded the geographic representativeness of their retail meat testing to include three new states: Washington, Louisiana, and Missouri.
Department of Agriculture 5.

Closed - Not Implemented
According to FDA officials in 2013, efforts to research antibiotic alternatives include participation in meetings related to encouraging new technologies related to new drug products. FDA officials also stated that FDA's Center for Veterinary Medicine has an Innovative Technologies Initiative that is conducting outreach with industry to identify ways to better accommodate nontraditional products, such as those that replace antibiotics in FDA's product approval process. In March 2015, the White House issued the National Action Plan for Combating Antibiotic-Resistant Bacteria, superseding the 2010 interagency plan. In September 2015, FDA officials stated that the agency is working on implementing steps to address gaps in research on antibiotic alternatives as outlined in the White House's National Action Plan. The plan identifies various future milestones with timeframes from one to five years to identify and close these gaps so actions may not occur in the near future.
