Non Technical Summary
The Food Animal Residue Avoidance Databank (FARAD) is a collaborative university-based food safety program that iscoordinated and delivered by veterinary faculty and staff at several US colleges of veterinary medicine. Throughout its 39 yearsof existence, FARAD has continued to evolve to meet the ever changing demands of providing accurate, timely and reliableservice to both the veterinary profession and food animal industry stakeholders. At present, the program is managed through avery close collaboration of personnel at the University of California-Davis (UCD), University of Florida (UF), North Carolina StateUniversity (NCSU), Kansas State University (KSU) and Virginia-Maryland College of Veterinary Medicine (VM).

Goals / Objectives
The 2021-2022 FARAD project year will continue to be focused on the essential call center tasks including answering extra-label withdrawal requests, updating and expanding the resources available to call responders, maintaining the call center database and index resource page, extracting and cataloging pharmacokinetic data from published literature and updating and developing educational tools for veterinarians and the public posted on the FARAD web site. Specific to this year, we will convert the .NET database framework to Ruby on Rails framework to make the overall function of the database and on-line interfaces more stable. Additionally, we will continue the process of developing artificial intelligence techniques to extract pharmacokinetic data from the literature. The UC Davis region will provide the opportunity for a Pharmacy Fellow to get experience at UC Davis with pharmaceutical related issues for food animals. In addition to the call center activities, we will continue to expand our efforts on educating small animal veterinarians regarding extra label drug use in backyard poultry, continue to assist veterinarians nationwide to understand the new veterinary feed directive rules, and provide California veterinarians with resources to conform with Senate Bill 27. Educational focused activities will be to develop curricula for pharmacists so that they are more aware of practices in veterinary medicine. Given the veterinary feed directive legislation and the California Senate Bill 27, the need for veterinary pharmacists is imperative for drug distribution and oversight in the future. UCD will continue to collaborate with the other FARAD regions on animal related projects that will generate data that are specifically needed for answering extra-label drug use inquiries. UCD will lead the charge for top priority drugs for backyard poultry and also help with small ruminant related studies. The data generated from these studies will allow FARAD to develop pharmacokinetic models that can be used for answering extra label drug use calls for these species. The drugs and species for which the studies will be performed will be dependent on submissions to the call center. Examples would be evaluating extra label administration of meloxicam to lactating dairy goats and fenbendazole use in poultry.
Project Methods
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 derivedfrom food-producing animal species. The underlying activities that support these functions are carried out through multi-layeredand complimentary approaches that are coordinated by the FARAD centers located at UCD, NCSU, UF, KSU 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 isextracted, modeled, and entered into a computer-based archival databank that is readily searchable for customized informationretrieval. Because there are many factors that can influence how rapidly an animal eliminates a chemical residue; informationabout 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?Graduate (PhD) and veterinary students were trained in the area of drug residue avoidance and extra label drug use relative to food safety. Post-doctoral fellow, Dr. Melissa Mercer was also trained during this period. She expanded her knowledge in the area of estimating withdrawal intervals, analytical skills, and live animal studies for estimating withdrawal intervals based on drug residue studies. How have the results been disseminated to communities of interest?Information is shared with communities of interest via answers to ELDU questions, journal publications, information posted on the FARAD web site, and scientific presentations. What do you plan to do during the next reporting period to accomplish the goals?Continue to provide service to producers and veterinarians regarding on label and extra label drug use. Maximize availability of educational materials regarding residue avoidance.

Impacts
What was accomplished under these goals? The main programmatic accomplishments during this period were answering drug residue inquiries (10/1/2022-9/30/2023: 5,465 specific inquiries directly impacting 5.5 million animals) and updating and maintaining the pharmacokinetic, bibliographic, and call submission databases. FARAD telephone, email and web-based inquiries were answered on a rotating basis between UC Davis, North Carolina State University and Virginia Tech University. UC Davis continued collecting bibliographic citations that contain pharmacokinetic data from live animal studies. There was an ongoing process of adding new citations to the end note library. Between 10/1/2022-9/30/2023, 219 citation and 858 kinetic records were added, and 2,877 kinetic records were modified to expand the recorded data. Other extraction efforts included going back into the database and modifying kinetic records for accuracy and completeness focusing on small ruminants. For all citation and kinetic records, active ingredients and species were targeted for which FARAD gets the most submissions and for active ingredients that are being used extensively for ELDU. Citations were assigned a designation of importance then extracted and the pharmacokinetic data added to the database. The data extraction that UC Davis performs is crucial for developing residue avoidance algorithms and for responders to estimate withdrawal interval recommendations. Accomplishments for modifications of the on-line applications and the databases themselves during this review period included the following: New or redesigned farm call features: ·Added show/fair animal checkboxes. ·Call basis feature added. New or redesigned kin entry features: ·Time vs Concentration interface updates to make it easier to enter the data. New or redesigned BibKin finder features: ·Improved query for better search results. ·Included combo and co-administered drugs. ·Added additional matrix filter checkboxes. ·Bibkin finder "full" added - this is a data dump of basically everything about a kin entry record, including biblio and combo/co-administered drug information. It provides more information than the responder bibkin finder. New or redesigned Veterinary Feed Directive Educator features: ·Swine and cattle education modules were developed throughout the year. We focused most of our effort on cattle because of the complexity of the requirements. The California Department of Food and Agriculture helped to test features of the educator during development. Other notable accomplishments: ·Knowledge transfer of Florida FARAD regional center's duties to be handled by California. ·Added a feature to the FARAD application to edit or archive drugs in the database. Includes chapter information and alternate names. ·Started the process of farm call drug list clean-up. Working to improve the farm call search for responders. For the analytical laboratory standpoint, the number and types of samples analyzed included: Florfenicol Goat- 228; Ivermectin Chicken- 1048; Total - 1276.
