AADAP Update
Terramycin Drug Update
CVM approved the supplemental new animal drug application (NADA) for Terramycin® 200 for Fish. The supplemental approval of Terramycin® 200 for Fish (oxytetracycline) Type A medicated article provides for a change in the bacterial species of Aeromonas liquefaciens to Aeromonas hydrophila in the approved indications for salmonids and catfish. 
INAD Program Accomplishments
AADAP’s INAD Program has reviewed the 2017 INAD studies and compiled information to share. The 2017 INAD Program had 232 investigators enrolled who participated in 16 INADS held by the USFWS in 2017. A breakdown of the type of facilities that conducted these studies includes 121 state facilities, 48 private facilities, 45 federal facilities, 9 tribal facilities, and 9 universities. A total of 731 INAD studies were completed and involved approximately 31.3 million fish. Over 73 different species, including marine species, game fish, minnows, and threatened and endangered species, were treated under USFWS INADS in 2017. These studies show that the INADs are safe, effective, and ultimately result in more fish stocked for fishing, restoration, or commercial harvest

FDA Center for Veterinary Medicine Update
Notice of Availability of Guidance for Industry #3 Evaluating the Human Food Safety of New Animal Drugs Used in Food-Producing Animals
FDA Center for Veterinary Medicine has issued a final Guidance for Industry #3, titled 'General Principles for Evaluating the Human Food Safety of New Animal Drugs Used in Food-Producing Animals', which "... describes the type of information that [CVM] recommends sponsors provide to address the human food safety of new animal drugs used in food-producing animals. The human food safety evaluation of new animal drugs used in food-producing animals helps ensure that food derived from treated animals is safe for human consumption. CVM developed this guidance to inform sponsors of the scientific data and/or information that may provide an acceptable basis to determine that the residue of a new animal drug in or on food, when consumed, presents a reasonable certainty of no harm to humans ..."

AAFV Contributes to the New AVMA Policy on AMR Strategy and Stewardship
(January 2018 update by Janet Whaley)
The AAFV is a voting member on the AVMA Committee on Antimicrobials (CoA); Dr. Janet Whaley (primary) and Dr. Pat Gaunt (alternate) serve on the CoA since its inception in 2016.  This month, the AVMA House of Delegates approved the U.S. veterinary profession’s first ever definition of antimicrobial stewardship and core principle regarding antimicrobial resistance (AMR). The AVMA considers this an important first step in the association’s commitment to provide resources and tools for veterinarians that support conscientious decision-making in the use of antimicrobials. The AVMA encourages veterinarians to implement one or more of the following principles of antimicrobial stewardship:

  • A clearly stated commitment by veterinarians to stewardship;
  • Support for systems of care that include a multi-pronged approach to  preventing common diseases;
  • Judicious selection and use of antimicrobial drugs;
  • Ongoing evaluation of the efficacy of antimicrobial drug-use practices; and
  • A commitment to professional education research that expands the profession’s knowledge base and supports good decision-making.

Auburn developing vaccine that could be huge catch for catfish industry
By Robert DeWitt  - January 9, 2018
Auburn University researcher Cova Arias has developed a vaccine that may save catfish from one of the deadliest diseases afflicting them -- and save catfish farmers a lot of money. See rest of story here.

“Emerging Animal Disease Preparedness and Response Plan” Released
The plan outlines a strategy to "... detect and respond to emerging animal diseases and define the processes that [the Animal and Plant Health Inspection Service (APHIS)] will use to identify, evaluate, and respond to emerging diseases in animal populations ... Rather than providing a single process to fit all emerging diseases, the VS plan outlines roles and responsibilities across VS business units for evaluating animal health information and determining response options ... This plan outlines several options, including development of case definitions, conduct of on-farm investigations, development and distribution of communication materials, increase in diagnostic capacity , and establishment of regulations for a new program or policy ..."

Animal Drugs at FDA' Searchable Database has been Updated by the FDA Center for Veterinary Medicine

The October 25, 2016 FDA CVM Update, titled "Search Approved Animal Drugs on the Redesigned Animal Drugs at FDA", is posted at

The Animal Drugs at FDA website is available at

Questions about the redesigned Animal Drugs at FDA website may be directed to CVM by e-mail at


In our continued effort to improve transparency and public access to information about approved animal drugs, the U.S. Food and Drug Administration’s Center for Veterinary Medicine is launching Phase III of the redesigned Animal Drugs @ FDA website.

As before, the new Animal Drugs at FDA website provides a searchable database for veterinarians, pet owners, animal producers and others to get information about approved animal drugs by application number, sponsor name, proprietary name, ingredient, application status, dosage form, route of administration, indication and species.

With the completion of Phase 3 on December 6, 2017, Animal Drugs at FDA will now display animal drug information using the FDA Structured Product Labeling (SPL) style sheet. This enhancement will permit CVM to post, approved animal drug SPL files in the future. Once posted, approved animal drug SPL files will provide additional information that includes all content of labeling and images of labeling components. Additional enhancements that were completed in this phase include:

* Adding of the marketing status to the search results table to better distinguish between approved and voluntarily withdrawn applications
* Updating the Advance Search Logic to always use “and” searches instead of “or” searches when entering multiple search criteria

Additional enhancements made on November 9, 2017, include:

* Creation of an FOI Summary display page listed by Application number
* Creation of an Environmental Documents page with all Environmental Assessment and Findings of No Significant Impact documents listed by chemical entities
* Creation of a Non-Steroidal Anti-Inflammatory Drugs (NSAID) labeling page which displays package insert and client information sheets for some NSAID products

U.S. Food and Drug Administration (FDA)
NEW Antibiotic Resistance Interactive Research Tool

The U.S. Food and Drug Administration (FDA) has launched an interactive research tool called Resistome Tracker which is "... one of the first publicly available tools to provide visually informative displays of antibiotic resistance genes in bacteria. It is designed mainly for public health officials, academics and researchers who are using new genomics technologies to track and treat infectious diseases.

Resistome Tracker's interactive interface allows users to customize visualizations by antibiotic drug class, compare resistance genes across different sources, identify new resistance genes, and map selected resistance genes to geographic region ... The tool also provides alerts about new resistance traits as they emerge in a region or source to provide early warning on emergent trends ...

Currently, Resistome Tracker is focused on antibiotic resistance genes in Salmonella ... Future iterations of the tool will include data on other microorganisms such as E. coli and Campylobacter as well as additional gene categories such as serotype, sequence type and virulence genes ..."

GAO Report

Imported Seafood Safety - Preventing Unsafe Drug Residues
The US Government Accountability Office (GAO) has issued a report which found that "... FDA could strengthen its efforts to ensure the safety of imported seafood from unsafe drug residues by pursuing agreements with other countries requiring that they test seafood exported to the United States for unsafe drug residues ... FDA has used country agreements with respect to pathogen hazards in molluscan shellfish intended for export to the United States. According to FDA officials, it might be worthwhile for the agency to pursue agreements with some countries, but FDA would have to carefully consider a number of factors in determining which countries would be appropriate, which it has not yet done ..."

FDA Clarifies Policy Guideline on Extralabel Use of Veterinary Feed Directive Drugs

 One of the highlights of the 23rd Annual Aquaculture Drug Approval Coordination Workshop held August 1-3, 2017 in Bozeman, MT, was the series of presentations and panel discussion of Veterinary Feed Directives (VFDs) led by Dr. Mike Murphy (CVM Office of the Director, Science Policy Team). 

The VFD-themed session was organized because there has been considerable confusion over extra-label use of VFD drugs as described by the Compliance Policy Guideline (CPG) released in December 2016. Although such use is illegal, Dr. Murphy pointed to the sentence in the Guideline (CPG 615.115; page 5) that states "In general, the Agency [FDA] will not recommend or initiate enforcement action against the veterinarian, animal producer, feed mill, or other distributor when extralabel use is consistent with this document."

Compliance Policy Guideline 611.115 is for Minor Species only and can be viewed on this web page.

The document contains useful information and veterinarians will probably are probably very familiar with what is described in the (1) General Considerations and (2) Veterinarian Considerations sections. 

What may be of most interest in this document is the Veterinary Feed Directive (VFD) Medicated Feed subsection that covers what a veterinarian must do when authorizing the extralabel use of a VFD medicated feed for a minor species (i.e., fish). 

It should also be pointed out that CPG 615.115 can be rescinded. Therefore, there needs to be a concerted effort to ensure compliance with extralabel use of VFD medicated feeds. In addition, it would be well advised, to let the sponsor, AADAP, and CVM know when extralabel use occurs so we can more strategically coordinate research to expand the approved label accordingly. 

For more information on veterinarian responsibilities when authorizing extralabel use of a VFD medicated feed for fish visitFDA Revises CPG on Extralabel Use of Medicated Feeds for Minor Species.


USDA ARS News Release

A Big Step towards Reducing Strep in Farm-Raised Tilapia
Researchers with the USDA Agricultural Research Service (ARS) Aquatic Animal Health Research Unit in Auburn, Alabama and industry partners have developed tilapia that are resistant to both Streptococcus iniae and Streptococcus agalactiae, the "... main culprits [that cause] tilapia farmers lose about $1 billion annually due to streptococcosis ..."

The researchers showed that "... selective breeding for disease resistance is a promising alternative [to] vaccines and antibiotics ... They found that crosses between the best performing fish were more resistant to the bacteria than other tilapia ... This milestone research paves the way for developing more lines of tilapia with resistance to other pathogens ... Data shows that the improved tilapia lines will save an average-size farm nearly $635,000 a year annually ..."

Don't have time to read the full article? Read the DRIB!  By Jim Bowker
How many times have you heard about a project that was underway or you’ve seen a presentation of some really useful information, but you had to wait months or even years to see the results in print? And when was the last time you actually read an entire technical article from front to back? AADAP has developed Drug Research Information Bulletins, or DRIBs. These are 1 - 2 page manuscripts that summarize successful fish drug field effectiveness and target animal safety work. In addition, AADAP is reaching out to others who are doing fish drug work that wouldn’t normally publish in peer-review journals and encouraging them to write a DRIB which will be shared through the AADAP website. All DRIBs are reviewed by internal and external sources before posting.
