Non Technical Summary
The Food Animal Residue Avoidance Databank (FARAD) is a collaborative university based food safety program that is coordinated and delivered by veterinary faculty and staff at several US colleges of veterinary medicine. Throughout its 40-year existence, FARAD has continued to evolve to meet the ever-changing demands of providing accurate, timely and reliable service to both the veterinary profession and food animal industry stakeholders. At present, the program is managed through a very close collaboration of personnel at the School of Veterinary Medicine at the University of California-Davis (UCD) and the Colleges of Veterinary Medicine at University of Florida (UF), North Carolina State University (NCSU), and Virginia-Maryland (VM), as well as at Kansas State University-Olathe (KSUO).

Goals / Objectives
The core mission of FARAD is to protect the American public by promoting the production of safe, animal-derived human food products (milk, eggs, meat, honey, etc.) that are devoid of violative or potentially unsafe chemical residues, including drugs, pesticides, environmental contaminants, natural toxins and other harmful substances. The overarching objective of the collaborating universities is to promote the continued development and foster delivery of the FARAD program. To that end, UCD, NCSU, UF, KSUO and VM will continue to employ the latest technologies to make changes in FARAD that will improve its usefulness and utility as a decision support system. The six primary focal points will continue to be (1) extraction and validation of data for incorporation into the system and support for FARAD's approved drug databases for publication in electronic format (VetGRAM) for internet-based delivery, including extraction of relevant data from foreign drug compendia and gFARAD partners, (2) operation of the Regional Access Centers (RAC's) at NCSU, VM and UCD for provision of residue avoidance information, with access through the toll-free hotline and e-mail, (3) data acquisition, data entry, pharmacokinetic analysis, maintenance, and distribution of the FARAD files, (4) preparation of FARAD Digests for publication in the Journal of the AVMA, newsletters and FARAD fact sheets/species information web-based pages (5) education of veterinarians on drug residue avoidance and (6) continued development and validation of methods to allow extrapolative techniques to be used in providing information and advice in situations where no direct data currently exists, which is typically required for nearly all environmental contaminant exposures.
Project Methods
In order to carry out its mission, the FARAD team collates, analyzes and interprets the most up-to-date information and uses that unique data repository to provide accurate and timely expert advice to assist veterinarians who are faced with situations that could cause unsafe chemical residues in human food products. In addition, FARAD maintains and provides an array of complete information resources for veterinarians, extension specialists, farmers, regulatory personnel and others who are the stewards of our nation's expansive commercial food animal industries and the growing number of small backyard livestock operations. Beyond those primary functions, FARAD has a secondary impact on the food consuming public and contributes significantly to human public health and consumer confidence by providing food animal specialists with the most up-to-date and comprehensive scientific information available today. Throughout four decades of delivering this program, FARAD has continued to develop increased sophistication with respect to (1) acquisition and cataloging of pharmacokinetic data and comprehensive information resources, (2) adapting efficient mechanisms for information delivery and outreach to target audiences, and (3) utilizing complex quantitative tools and models for accurately estimating safe withdrawal intervals for a wide array of drugs and chemicals in nearly all species of domestic food animals.FARAD performs a broad array of programmatic functions, but key among these are the collection, evaluation, analysis, interpretation and dissemination of information related to the depletion of drugs and other chemicals in edible products derived from food-producing animal species. The underlying activities that support these functions are carried out through multilayered and complementary approaches that are coordinated by the FARAD centers located at UCD, NCSU, UF, KSUO and VM. At UCD, FARAD personnel search the peer-reviewed scientific literature plus numerous other information resources for data pertaining to the depletion or elimination from food-producing animals of all classes of small molecule entities. Relevant information is extracted, modeled, and entered into a computer-based archival databank that is readily searchable for customized information retrieval. Because there are many factors that can influence how rapidly an animal eliminates a chemical residue, information about diet, age, gender, breed and disease status are taken into consideration.

Outputs
Target Audience: The Food Animal Residue Avoidance and Depletion (FARAD) program has a human food safety focus with services to veterinarians. The target audience for this program is livestock owners, producers, regulators, and veterinarians (private practice and state). The goal of the program is residue avoidance in human food products by providing livestock owners, producers, extension specialists, scientists, and veterinarians with information to prevent drug, pesticide, and environmental contaminant residues in food animal products that are intended for human consumption. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided? Nothing Reported How have the results been disseminated to communities of interest? Nothing Reported What do you plan to do during the next reporting period to accomplish the goals?Activities focusing around responses to ELDU inquiries will continue and the databases providing critical ELDU information will be updated and modified as needed.

Impacts
What was accomplished under these goals? • Accomplishments during this period focused on on-line applications for data extractors, FARM call responders, and veterinarians submitting inquires to the FARAD program. The following is a listing of completed or in progress tasks. 1. A complete modernization of the internal database (FarmCalls) that is used by FARAD responders to catalogue and respond to requests for withdrawal interval recommendations following ELDU was completed. This update dramatically improved responder workflow, resulting in increased data transparency, improved search functionality, and improved WDI calculation traceability--allowing responders to be able to efficiently and accurately respond to the increasingly high volume ofsubmissions. This update included the following: • New or redesigned FarmCalls features • Updated interface that aligns with current responder workflow • Ability to flag and highlight calls that contain withdrawal interval calculation basis updates • Ability to highlight calls that contain director approved case decisions • Ability to track basis updates by director approval • Updated species classifications to better identify production status, commonly submitted minor species, and differentiate poultry species • Ability to track submissions in research or show animals • Ability to track intentional vs. accidental prohibited extra-label drug use • Ability to search for calls by date range • Ability to filter calls to only show calls with a withdrawal interval calculation basis update • Ability to filter the past call search criteria for the food product withdrawal interval requested in the submission • Ability to view and sort the dose, route, frequency duration, and withdrawal interval provided for cases in the past call search function • Ability to assign a status to each submission request, allowing responders to communicate the submission status and where the submission is in the queue • Ability to assign a responder to each submission, and view the responder working on the submission on the incomplete calls page to improve responder communication 2. An update to the web-based submission form interface was completed in order to address mobile functionality, improve the user experience, and allow FARAD to provide more species and more drug administration units. This update significantly improved the accuracy of data collected and allowed veterinarians to better characterize their unique dosing scenarios. • New or redesigned submission form features • Updated interface is more visually appealing and optimized for mobile use • Updated workflow to better differentiate between submitter and veterinarian of record contact information • Updated submitter roles to better identify users who are not veterinarians • Updated species classifications to better identify production status in major species, create separate entries for commonly submitted minor species, and to differentiate poultry species • Ability to check if submission is for research or show animals • Updated route of administration units to allow veterinarians to more accurately define how the drug was given • Updated dose and frequency units to allow veterinarians to more accurately define their dosing scenarios • Updated ability for submitter to be able to define what food product or species is meant when the user selects "other" • Improved workflow to capture trade name information and to define free-typed entry space 3. New FARAD application features • Added a user edit feature. This includes some new features like updated roles/permissions, and the ability to mark a user as a student. 4. Farad.org and VetGRAM • Updated dates on farad.org and VetGRAM to reflect the latest updates to the database. • Prepared the database for mobile app updates on a quarterly basis. • Maintained a web page listing the updates that are on the VetGRAM website, but not on the mobile app since the app is only updated several times per year. • Configured a server on AWS to host VetGRAM in the future. 5. VFD Educator Application • Work has continued on this project to complete its functionality. The cattle educator has been the focus. • Included the ability to select trade names when filling out the educator form. This helps narrow down more accurate numbers for calculations. • Detailed warnings added to let the user know of any issues with the VFD or calculations based on the information on the VFD. • Icons have been added to the user interface with information to make it easier to understand the complexities of the educator. • Documentation has been written to describe the features and functions of the application in detail. This has helped everyone involved in the project to be able to understand the details of the application more clearly.
