4 CVM s Core Responsibilities New Animal Drug Review Animal Generic Drug Review Post-approval monitoring of animal drugs and feeds, and marketed animal devices Animal Feed Human Food Pet Food -- Protection/Safety Compliance related actions Research to support regulatory decision-making

5 Companion Animal and Minor Species Medicine CVM is responsible for regulating drugs, devices and food additives used in companion animals (dogs, cats and horses) and minor animal species ~72 million dogs & 82 million cats ~7 million horses Minor Species include all animals other than the following 7 Major Species: cattle, swine, chickens, turkeys, horses, dogs and cats.

6 Animal Health and Animal Food Product Safety CVM is also responsible for regulating animal drugs, devices and food additives used in food producing animals. From: Given to or used on: Consumed by: Animal Drug Manufacturers (300) Feed Manufacturers (6,600) Livestock and Poultry Producers (over 1 million) Specialized Industry/Firms 8.5 billion chickens & turkeys 160 million cattle & pigs 11 million sheep & goats 310 million humans in the U.S.

7 CVM s Business Priorities Related to foods: Transforming Food Safety Practices Implementing the Food Safety Modernization Act (FSMA) Animal Biotechnology (genetic engineering and cloning) Unapproved Animal Drugs Bovine Spongiform Encephalopathy (BSE) Illegal Drug Residues in Animal Derived Foods Antimicrobial Resistance (includes the National Antimicrobial Resistance Monitoring System [NARMS]) Turtles (Salmonella sp.) International Activities

8 Potential for GE Animals Biopharm Research Xenotransplant, scarce cells, tissues, organs Disease resistance Animal derived food products

9 Genetic Engineering Bio-pharm Bio-pharm animals also present a unique set of challenges. These are animals used to make human biologics or other therapeutics... (e.g. ATryn human anticoagulant a therapeutic protein produced in milk of GE goats.) CVM is still sorting through Compliance requirements. Sponsors are required to submit an application to CVM for review of the animal component. Other product Centers CBER and CDER will review the human therapeutic. Many sponsors do not realize that they are required to consult with or submit applications to CVM.

10 Unapproved Animal Drugs There are many unapproved drug products, including those that are compounded outside of what is allowed under AMDUCA, which places a strain on the marketplace These products may have a long history of use but have not gone through the FDA drug approval process to demonstrate safety and effectiveness CVM is currently soliciting comments through a Federal Register Notice that asks for input on potential legal homes for these unapproved drug products. Comment period closed on April 19 th Over 240 comments have been received. The majority of the comments refer to restrictions on compounding and most people are very opposed to the potential of losing the ability to compound from bulk.

11 BSE Inspections Shifting Focus This has been a very successful program with a consistent compliance rate of over 90% CVM would now like to shift some of our focus and resources to drug residue work. Most of the Center s residue-related efforts are currently focused on inspection of Food Safety Inspection Service (FSIS) identified animals presented at slaughter with violative drug residues. Resources currently allow for inspection of less than 50% of the violations reported to the Agency.

12 Tissue Residues CVM and CFSAN are now participating in an interagency working group with representatives from USDA s Food Inspection Safety Service (FSIS) and representatives of the Environmental Protection Agency (EPA) to develop a more consistent and collaborative approach to identifying and addressing tissue residues.

13 Shifting Focus Future efforts will also branch out into a milk sampling assignment which is currently making its way through the clearance process to test the hypothesis of whether poor on farm practices leading to drug residues in tissues are also leading to drug residues in milk.

14 CVM International Activities With leadership and resources from FDA s Office of International Programs, CVM carried out a number of capacity building projects overseas, including animal drug workshops. Representatives from CVM are key participants in a number of important Codex Alimentarius Activities: Chair of Codex Committee on Residues of Veterinary Drugs in Foods. Participating on Codex Task Force on Antimicrobial Resistance. Participating in Codex Electronic Working Group on Animal Feeding.

15 CVM International Activities In process to becoming an Official Collaborating Center with the OIE. CVM has ongoing surveillance and Global Monitoring of the Safety of Feed and Feed Ingredients. CVM manages the U.S. NARMS Program and Integration of the World Health Organization Global Food borne Infections Network. Provides expertise and content for International Capacity Building Project: Training Module on Aquaculture Drug Use

16 Purpose of the Aquaculture Training Module: (JIFSAN) Help foreign aquaculture producers understand what drugs & chemicals are allowed (or not) for use in US Includes: Definitions Regulating agencies Laws & regulations Policies & procedures Helps them understand: Food fish vs. nonfood fish Low Regulatory Priority unapproved drugs Extra label use HACCP Import tolerance MRL s Drugs approved in other countries

17 Other CVM Challenges -- Antimicrobial Resistance Provide safe use of antimicrobials in food animals while ensuring that significant human antimicrobial therapies are not compromised or lost Increasing resistance to antibiotic treatment in bacteria that infect humans raises concerns about the role that drug use in food-producing animals may play in the emergence of resistant bacteria. Monitoring resistance among enteric pathogens in both animals and humans through National Antimicrobial Resistance Monitoring System (NARMS). E. coli

18 Recent CVM Actions Availability of Draft Guidance (#209) The Judicious Use of Medically Important Antimicrobial Drugs in Food-Producing Animals Advance Notice of Proposed Rulemaking - Veterinary Feed Directive.

19 National Antimicrobial Resistance Monitoring System (NARMS) NARMS is a national public health surveillance system that tracks antibiotic resistance in foodborne bacteria.

27 Vet-LRN Veterinary Laboratory Response Network What is the mission? To promote human and animal health by collaborating with veterinary diagnostic laboratories to provide scientific information, to build laboratory capacity and to train scientists investigating CVM regulated products (animal feeds/animal drugs)

28 Vet-LRN Veterinary Laboratory Response Network How: Develop infrastructure through Communications network, Cooperative agreement/grants/contracts, Training/Proficiency exercises

29 Vet-LRN Veterinary Laboratory Response Network And WHY do we need it?

30 Animal is sick Lab work Vet bills Contact FDA Was it the food?

31 What does CVM want? Veterinary Records

32 What does CVM want? Veterinary Records Collect Feed/Drug samples

33 What does CVM want? Veterinary Records Collect Feed/Drug samples More Tests? Necropsy? Histopathology? Who Pays?

34 Need a system to help investigate potential pet/livestock food/medicine related disease

35 Need a system to help investigate potential pet/livestock food related disease CVM is developing a new network similar to the FERN system (smaller)

36 Where does Vet-LRN fit in? We don t need to re-invent the wheel Small program 2 People in Office of Research, 1 Person in Office of Surveillance and Compliance 1 Contractor

37 March 2011 stakeholder input Veterinary Diagnostic Laboratories Develop contacts with CVM Describe capabilities Describe needs

38 Who all is interested?

39 What makes Vet-LRN unique? Vet-LRN diagnostic labs will help with the surveillance of veterinary cases unlikely to come into food testing laboratories on a routine basis. Vet-LRN will analyze diagnostic samples from livestock and companion animals exposed to adulterated/contaminated food and drugs Vet-LRN wants to work with the other networks, not in isolation Vet-LRN will fund projects outside the current mission of other networks
