New Era of Smarter Food Safety: FDA’s Foodborne Outbreak Response Improvement Plan

Tackling foodborne outbreaks faster and revealing the root cause are essential for the prevention of future outbreaks. We have a plan to do that.

Foodborne disease remains a significant public health problem in the United States. The FDA’s Foodborne Outbreak Response Improvement Plan (FORIP), described in this document, is an important step that the FDA is taking to enhance the speed, effectiveness, coordination, and communication of outbreak investigations. (Unless stated otherwise, this report focuses exclusively on the response to human food and not animal food.)

Our ultimate goal is to bend the curve of foodborne illness in this country.

I. What are the challenges we are facing?

Foodborne pathogens are estimated to sicken one in six Americans each year. This results in an estimated 128,000 hospitalizations and 3,000 deaths. The food system in the United States is large, distributed, and decentralized, with a broad array of widely distributed products. Foodborne outbreaks require multidisciplinary efforts and often multijurisdictional coordination.

Changes in identifying, investigating, and controlling foodborne disease outbreaks present new challenges and opportunities in the 21st century. Our ability to detect more outbreaks and smaller outbreaks through new technologies and advances in subtyping, such as whole genome sequencing, has likely increased the number of multistate outbreaks identified in recent years.

While progress has been made, we need faster and more streamlined investigations to identify and remove contaminated food from the market, and more effective investigations to identify deficiencies in the food system to help prevent similar outbreaks in the future. These are serious concerns that we must address. 

II. What progress have we made to date?

The FDA and its partners have pursued multiple approaches to reducing illnesses attributed to foodborne pathogens. Since the passage of the 2011 FDA Food Safety Modernization Act (FSMA), the Agency has taken many steps to prevent contamination of food by utilizing a modernized approach to identify and control various food safety hazards. The same year that FSMA became law, the FDA established FDA’s Coordinated Outbreak Response and Evaluation (CORE) Network, composed of a dedicated staff of personnel with expertise in medicine, public health, and science, to coordinate the Agency’s efforts to find, reduce, and work to prevent foodborne illness outbreaks in people.

For more than a decade, the FDA has been at the forefront of working with other federal, state, and local health authorities to implement advanced outbreak investigation tools to more rapidly identify contaminated food and to determine how contamination of the food occurred.  During outbreak investigations, restaurant and grocery purchase data voluntarily provided by persons that became ill can provide critical information for both the epidemiological and traceback investigations. This information is often referred to as consumer purchase data. Outbreak investigation tools include the utilization of purchase data voluntarily provided by ill consumers to assist in identifying common foods purchased in an outbreak and the use of whole genome sequencing to provide important information on the genetic make-up of the pathogen.

CORE efforts have been enhanced by close collaboration with the Office of Regulatory Affairs’ (ORA) emergency response coordinators and state liaisons. Historically, FDA has depended on its many partnerships to advance foodborne outbreak response. Specifically, FDA has been integrally involved with the Council to Improve Foodborne Outbreak Response (CIFOR) since its inception in 2006, as well as the federal Interagency Foodborne Outbreak Response Collaboration (IFORC), formed in 2013. This plan will complement these efforts and will depend on FDA partners for its success. Notably, CIFOR is comprised of federal, state and local officials from health and agriculture, and also includes an industry workgroup.

Another example of progress is the continuing expansion of Rapid Response Teams (RRTs), state-based teams that train and coordinate with FDA and respond to any food hazard. The RRTs now exist in more than 20 states and are an excellent example of domestic mutual reliance and federal-state coordination and collaboration.

In 2019, the FDA launched the New Era of Smarter Food Safety, an initiative that builds on the foundations laid by FSMA, with an increased focus on leveraging technology and other tools to create a more digital, traceable food system, and thereby a safer food supply. In 2020, the FDA released the New Era of Smarter Food Safety Blueprint, which outlines specific approaches the FDA and others will take over the next decade to address food safety in the rapidly changing food system. The blueprint contains four “Core Elements,” which address new food safety challenges the food system will face as well as new technologies (e.g., tracing technologies, genomics, advancements in detection methodologies, and advanced analytics) that can be harnessed to improve food safety.

This Foodborne Outbreak Response Improvement Plan is focused on multi-state outbreaks that require significant engagement coordinated by FDA’s CORE Network. This plan is intended to complement two of the blueprint’s Core Elements: “Tech-Enabled Traceability” and “Smarter Tools and Approaches for Prevention and Outbreak Response.” It is also important to recognize that many foodborne outbreaks occur at the local level and are tied to contamination that occurs in retail settings, which is the focus of separate activities under the Core Element "New Business Models and Retail Modernization." 

III. What was the basis for developing this FORIP?

The FORIP was developed as an extension of, and in coordination with, the Core Element work described above, which stemmed from the New Era for Smarter Food Safety Blueprint and the stakeholder engagement efforts that informed both the development and the implementation of the blueprint. FDA leadership and staff across the foods program have continually considered ways to improve the FDA’s outbreak response. Their observations and recommendations played a key role in the development of this FORIP.

In addition, the FDA contracted with the University of Minnesota’s School of Public Health to better inform the outbreak-related work being conducted under the New Era of Smarter Food Safety Blueprint. The resulting independent report [1] was based on interviews with more than 25 senior FDA officials, as well as senior federal officials in the United States Department of Agriculture’s (USDA) Food Safety Inspection Service (FSIS) and the Centers for Disease Control and Prevention (CDC), state health officials, and industry and consumer foodborne outbreak experts. It provides an objective assessment of the FDA’s structural and functional capacity to support, participate in, or lead multistate foodborne illness outbreak investigation activities. The report, which included a series of recommendations, also played a key role in the FDA’s development of this FORIP.

IV. What will this FORIP focus on and why?

The independent report examined the FDA’s roles and responsibilities, processes, priorities, decision trees, and procedures for foodborne outbreak response in three specific areas:  product tracing, root cause investigations, and the use of CORE data. We believe that improvements in these three areas will play a significant role in improving the speed, accuracy, and effectiveness of the FDA’s overall outbreak response and coordination with relevant federal, state, local, tribal, territorial, and international counterparts, and industry stakeholders. Themes of increased transparency and trust with partners are woven throughout. While the plan focuses heavily on actions FDA pledges to undertake, we acknowledge the interdependencies that exist in outbreak response requiring a true food systems approach for success. In addition, we have added a fourth category to the FORIP, operational improvements, as we recognize that several recommendations fit well into this category.

  1. Tech-enabled product traceback – The FORIP focuses on smarter ways to digitize and routinize the traceback process. We will improve our utilization of consumer purchase data to better specify critical traceback information we need from industry, which will streamline additional traceback steps. We will facilitate and expedite how FDA will receive the data, and we will use more advanced analytical methods and computational approaches to prioritize the highest value traceback leads to pursue. We will also work to harmonize our efforts with our relevant federal, state, local, tribal, and territorial counterparts so that they too will be able to advance how they request, receive, and analyze traceback data. We will also work with industry and other stakeholders involved in tracebacks to show them new processes and encourage/help them adopt these new techniques for their traceback efforts.
  2. Root cause investigations (RCIs) – The FORIP focuses on systematizing, expediting, and sharing FDA RCIs. We will adapt and strengthen protocols and procedures for conducting timely RCIs to ensure we can conduct simultaneous investigations, when necessary. We will standardize criteria and formats for producing reports on RCIs of outbreaks. We will expedite the release of investigation findings and their implications directly with the affected industry and to the public. We will determine the most expedited process for disseminating necessary public health information and actions to prevent a reoccurrence. With appropriated funds, we will seek to enhance staff and resources to manage anticipated increases in root cause analyses.
  3. Analysis and dissemination of outbreak data – The FORIP focuses on ways to strengthen our analysis and dissemination of outbreak data. We will work with CDC, USDA-FSIS, and other health partners to identify reoccurring, emerging, and persistent strains of pathogens. We will facilitate sharing of data with CDC and other regulatory partners. We will increase transparency of outbreak investigations to increase widespread public confidence in results and help facilitate improved collaboration on investigation activities.
  4. Operational improvements – The FORIP focuses on continuous operational improvements that will enhance product tracing, root cause analysis, and the use and dissemination of outbreak data. We will streamline the internal process used to make field assignments and information requests. We will work to assure that RCI findings result in an actionable prevention strategy and help determine FDA food program priorities. Importantly, we will build in performance measures across the FDA’s foods program to better evaluate the timeliness and effectiveness of outbreak and regulatory investigation activities.


The actions identified below were developed by the FDA and informed by both internal and external reviews of current outbreak response activities. The chart identifies the key goals and activities the FDA intends to undertake to improve its outbreak response aimed at preventing additional illnesses. The activities listed in this chart will likely necessitate additional internal actions with respect to the FDA’s current procedures. While this FORIP doesn’t provide that level of granularity, the Agency will undertake these internal measures as it works to achieve the goals and milestones identified in the chart. The focus of this plan is on human food; however, some of these activities may be considered and applied to respond to foodborne outbreaks involving animal food.

VI. How will we evaluate success?

We stated that the goal of this plan is to enhance the speed, effectiveness, coordination, and communication of outbreak investigations. We will use a combination of performance and outcome measures to assess the extent to which we are able to accomplish that. Further, we will measure our progress in accomplishing the actions set forth in this plan, and we remain committed to continuous improvement.

VII. How will we engage with stakeholders?

We prioritize transparency and openness in implementing this plan. We will update stakeholders on our progress at various points in the process and engage stakeholders both to solicit their ideas and feedback. In addition, we will publish an annual report detailing the progress made on specific deliverables identified in this plan.  Other government agencies at the federal, state, local, territorial, tribal, and international levels, as well as industry and consumers, are critical stakeholders and partners working with the FDA to strengthen outbreak response in the United States. This plan specifically identifies key efforts the FDA will undertake in concert with these partners. In addition, we plan to hold a stakeholder webinar in early 2022 to describe this plan and respond to questions. And we will post updates to our website as we meet our major milestones.


The FDA has set forth in this plan a series of actions we intend to take to respond more quickly and more efficiently to foodborne outbreaks and reduce the number of foodborne outbreaks that go unsolved in the future. Continued investments throughout the FDA and the food safety system will be critical to modernizing and strengthening our response to foodborne outbreaks, as well as to accomplishing the goals stated in this plan. We commit to streamline and expedite our outbreak response, to leverage digital data, to use more sophisticated analytical methods, to work hand-in-hand with our government, industry, and consumer partners, to learn from past outbreaks, and to communicate necessary information, in a timely and effective manner, to help prevent future outbreaks. We are resolute in our commitment and in our belief that this will help achieve our ultimate goal of bending the curve of foodborne illness in the United States.
