Module Descriptions:

Introduction: What is an emergency response? How is this program going to be organized? How can the emergency poultry disease response model be used for other animal emergencies?

Outbreak Response: What is the “Avian bird flu”? How does AI spread? What are hemagglutinin and neuraminidase, and what do they do? What are the priorities and key steps in an AI response?

Zoonotic & Foreign Animal Diseases: Why do existing and emerging zoonotic and foreign animal diseases represent a continuing threat to national and international agriculture, human health, and national security? How the confluence of veterinary and human health should require the “One Medicine Concept” approach to dealing with the problem.

Current Avian Influenza Situation: What is the status of AI outbreaks around the world? Where have recent outbreaks occurred and are there outbreaks currently taking place.

Case Report on Avian Influenza in Mexico: Participants from Mexico will be encouraged to report on the recent outbreaks of HPAI in Mexico and how the outbreaks have been handled? What are the lessons learned?

Personnel Protective Equipment: What types of personal protective equipment (PPE) are required during an outbreak response? The use and appropriateness of N95 masks, powered air purifying respirators and self contained breathing apparatus will be discussed.

PPE and Biosecurity Procedures for Proper AI Surveillance Swab Collection: What types of personal protective equipment (PPE) and biosecurity procedures are required to collect surveillance field samples properly?

Proper Surveillance Swabbing-Hands-On: Demonstration and participation in proper collection of field samples and the use of personal protective equipment.

Surveillance in Wild Birds and Poultry: A critical step in emergency poultry disease preparedness and response involves wild bird and commercial poultry surveillance programs. These programs involve the testing of migratory birds nationally and internationally including the USDA, DOI and its cooperators (including the State of Delaware and the University of Delaware). In January 2006, the U.S. commercial poultry industry initiated an avian influenza testing program. All broiler flocks from participating companies, including all four broiler companies on the Delmarva Peninsula, are tested and confirmed AI negative before going to slaughter.

Biosecurity and Protecting the Responder: Biosecurity is one of the principle steps in preventing the spread of disease. Biosecurity is the one aspect of avian influenza control that can be practiced on a daily basis. Examples of current methods, including risk assessment biosecurity programs will be discussed. Human health precautions to protect outbreak responders will also be discussed

Application of Incident Command Systems (ICS) to Poultry Emergencies: ICS is a scalable framework designed for emergency response. ICS can be used for emergencies such as fire protection to poultry diseases response. The same framework can be used for disease response, structural incidents, and similar.

Delmarva’s Outbreak Response: The Delmarva Peninsula is a high density poultry production region. In 2004, a LPAI outbreak on Delmarva was contained after relatively limited spread due to a well developed response plan that was in place before the outbreak. The plan had a clear cut emergency management structure. Poultry emergencies require a multifaceted response and control strategy. After the detection of an avian influenza outbreak, all response plans involve quarantine, further testing of flocks in and around the quarantine zone, then depopulation, decontamination including carcass disposal, cleaning and disinfecting. The successes of the

2004 response, along with lessons learned from that response, have been used to guide the development of new emergency response procedures.

Other Models of Control-Vaccination and Controlled Marketing: Depopulation is one approach used to control the spread of avian influenza and other diseases. Vaccination and controlled marketing can be key tools for the prevention and control of avian influenza. Both techniques are used internationally. Vaccination can be used to help contain outbreaks, reduce viral shedding, and decrease transmission, but can also reduce detection of sick birds.

Guidelines, Methods and Criteria for Depopulation: There are a limited number of mass emergency depopulation procedures. Guidelines from the US Department of Agriculture, American Veterinary Medical Association, OIE, and others guide the selection of appropriate depopulation techniques. The advantages and disadvantages of several gas depopulation techniques will be discussed.

Foam Depopulation: Foam depopulation was developed as a fast, humane, and easy to implement mass emergency depopulation procedure. The procedure reduces the number of people required and can rapidly depopulate floor reared poultry. Participants will learn the characteristics of foam, the science behind the procedure, and how to implement foam depopulation.

Foam Depopulation Demonstration: Two different water based foam depopulation methods will be demonstrated. Depending on time and conditions, participants will have the opportunity to operate the equipment.

Allen Laboratory Tour: The Allen Laboratory is a state of the art BSL 3 Ag facility that allows faculty and staff at the University of Delaware to perform cutting edge research with a variety of viruses and pathogens. The tour will include discussion of how the building was designed and a tour of the animal and laboratory spaces.

Disposal Options: After catastrophic poultry emergencies, whether avian influenza, heat stress, or otherwise, requires disposing of large numbers of birds. One of the critical concerns in selecting a disposal method is biosecurity. Depending on the circumstances, the options may be limited. The advantages and disadvantages of several disposal options including on-farm burial, landfilling, incineration, and composting are reviewed. The science and fundamental principles behind composting will be presented.

Implementing Composting: Composting is an effective on-farm means of inactivating avian influenza virus. Composting is suitable for international and domestic carcass disposal. Composting has been used for both daily and catastrophic mortality disposal. Daily mortality disposal has been successfully used on Delmarva since the 1980’s, while in-house composting is slightly newer. Procedures for both daily and catastrophic mortality are reviewed, including the mix & pile and layering techniques.

The United States Live Bird Market System: The United States has a number of regional live bird markets which are managed differently than the larger integrated commercial poultry industry. These differences can pose biosecurity challenges. Strategies to deal with the challenges of the US live bird market system will be discussed.

Incident Command Structures (ICS) and Perdue’s Lesson Learned: ICS is a scalable system used for commanding, controlling and coordinating the efforts of individual agencies as they work towards the common goal of stabilizing an emergency. The system provides the framework for people from multiple agencies to work together. In this module, representatives will discuss how ICS was part of Perdue’s response during regional poultry disease emergencies.

Composting Demonstration: Both daily and catastrophic composting will be demonstrated.

Cleaning and Disinfection: How are disinfectants classified? What are the advantages and disadvantages of these different classes of disinfectants? What is different about the newer generation of disinfectants? What is the impact of organic material on the efficacy of these agents? What are the key characteristics of a disinfection strategy? Which chemicals should be used and how should they be applied? What consideration should be given to disinfecting equipment?

Equipment Disinfection Video Demonstration: Skid steer loaders are extensively used in United States emergency management situations. One of the problems of using skid steer loaders is disinfecting the equipment after the outbreak. Unfortunately, disinfecting the equipment can be problematic, with numerous occluded spaces and blind holes. In this video demonstration, participants will be shown liquid spray and thermal fog equipment operation..
