Non Technical Summary
Current biosecurity procedures to prevent or respond to transmission of porcine pathogens have not been based on science, and the efficacy of these protocols is unknown. The purpose of this project is to identify the biosecurity procedures that are needed to prevent and respond to transmission of porcine pathogens. We expect that this initiative will have wide impact on policy design as governments and livestock producers revise their disease control procedures for both enzootic and exotic diseases. The research will immediately begin to address needs of the agricultural industry to maintain a healthy and safe food supply for our nation.

Goals / Objectives
Objectives: Our long-range goal is to identify the biosecurity procedures that are needed to prevent and respond to transmission of porcine pathogens. The objectives of this particular application are: (1) To identify effective decontamination protocols to prevent mechanical transmission of pathogens by fomites (2) To develop a database of resources to be used in an animal health emergency (3) To develop a searchable database of available disinfectants for use in the animal health industry.
Project Methods
Methods: Numbers of samples/animals needed and controls: Sample size will vary with project. For decontamination trials, at least 16 pens or 12 trailers will be used for each experimental treatment. Surfaces to be sampled within each pen include flooring, feeders, walls, gates, waterers, pigs etc. Flooring, walls, and ceilings of trailers will be sampled. A group size of 16 pens is equivalent to that used on typical swine farms. A group size of 12 trailers is the maximum feasible number of trailers to be washed in a single day. For testing decontamination methods sample sizes will be sufficient to allow us to detect a statistically significant difference (P<0.05) in endpoints among groups. Each experiment will have positive and negative controls (1) To identify effective decontamination protocols to prevent mechanical transmission of pathogens by fomites . Classes of disinfectants, detergents, and other decontamination procedures (ie flaming) will be tested during routine farm procedures such as room, equipment, trailer sanitation to determine the most efficacious, cost-effective, farm-specific disinfectant and disinfection procedures. Cultural examination will be performed to determine if disinfection occurred. Disinfection will be classified as isolation of < 1000 viable bacterium/cm2 of surface tested (Bohm, 1998). Mean or median bacterial counts before and after treatments will be compared using a GLM repeated measures analysis followed by post-tests when indicated. (2) To develop a database of resources to be used in an animal health emergency. A secure searchable database of resources available in case of an animal health emergency will be developed. Data will be provided by community members. One authorized emergency management person for each county will validate the data. The database will be available 24/7 for use by emergency responders in an animal emergency. (3) To develop a searchable database of available disinfectants for use in the animal health industry. Label claims from disinfectants will be used to develop a searchable database available to the general public. The database will be accessed via the internet and disinfectants will be searchable by name, manufacturer, class, and label claims.

Outputs
OUTPUTS: The project consisted of two objectives. Objective 1 was to develop the specialty curriculum needed to prepare veterinarians and other professionals for preventing and responding to animal health emergencies. We accomplished this objective by developing sixteen new graduate courses for a total of 14.5 credit hours. The courses are currently being offered to participating students. All courses were approved by the Graduate School at Purdue University. Additionally, APHIS reviewed the program and declared the curriculum in compliance with National Animal Health Emergency Management System (NAHEMS) Guidelines. Courses, course descriptions, and participating experts are described in detail at http://www.biosecuritycenter.org/article/HLScourses Objective 2 was to use a distance learning model to present the Veterinary Homeland Security Graduate Certificate Program to practicing veterinarians. We successfully continue to deliver this program via the web (www.biosecuritycenter.org) to all participants. We expanded the audience to include other non-veterinarians who might participate in animal-related emergencies. Each course site contains the course syllabus, objectives, course modules with instructor information, course bulletin board access, study guide, and any online supplementary reading materials. The website accommodates different learning styles and students can select a personalized delivery method from the following three options: 1- audio, video and slides; 2- audio and slides only; or 3-transcripts with or without embedded slides. PARTICIPANTS: The following individuals provided updated lectures for courses in the Graduate Certificate Program in Veterinary Homeland Security in 2011: Dr. Marianne Ash, In State Board of Animal Health, Dr. April Johnson, Purdue University. TARGET AUDIENCES: The target audience represents anyone that might be involved in an animal-related emergency. Currently, our participants represent the following groups: private practice veterinarians, emergency managers, government employees, veterinary technicians, veterinary students, university faculty; uniformed services, private industry, and diagnostic laboratory personnel. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

Impacts
To date, we have had 123 participants from 33 states, Washington D.C., Puerto Rico, Canada, Bermuda, Singapore, and South Korea enrolled in the Veterinary Homeland Security Graduate Certificate program. Fifty-nine students have completed the Community Planning service learning course and turned in projects including: contacting their local emergency managers; critiquing, updating, and/or writing plans for addressing animal emergencies in their communities; and, identifying community resources (personnel and equipment) to be used in the event of an animal emergency. Forty-six students have completed the entire program and received a graduate certificate in veterinary homeland security from Purdue University.Future initiatives planned are to develop additional courses and offer a web-based non-thesis Masters of Science degree in Veterinary Homeland Security. The program is currently undergoing the university approval process for new degrees.

Progress 10/01/04 to 09/30/05

Outputs
We continue to evaluate biosecurity procedures to prevent the mechanical transmission of porcine pathogens. First, aerobic bacterial culture was used to compare the effectiveness of the current USDA footwear disinfection protocol for airplane passengers contacting livestock to a novel protocol. The current protocol consists of brushing and dipping shoe soles in 1% Virkon S. The number of bacteria was not different between shoes treated with the current protocol and untreated shoes. No shoes met the standard for disinfection after the current disinfection protocol was completed. The novel protocol consisted of brushing shoe soles, wiping soles with a cotton towel soaked in 1% Virkon S, and drying soles with paper towels. The number of bacteria was less (P< 0.0001) on treated shoes compared to control shoes. Eighteen of 20 shoes (90%) cleaned using the novel protocol met the standard for disinfection. Direct comparison of the current and novel protocols found that the number of bacteria cultured was less (P< 0.0001) after implementing the novel protocol compared to implementing the current protocol. Again, no shoes treated using the current protocol met the standard for disinfection after the current protocol was completed. Sixteen and 17 of 20 shoes (80 to 85%), respectively, met the standard for disinfection after the novel protocol was completed. Under conditions of this study, current US airport footwear disinfection protocols were inadequate to disinfect footwear when using aerobic bacteria as a marker for disinfection. Second, we tested Monroe Liquid System's on-board tire sanitizer system as an adjunct tool in vehicle decontamination during the winter. This study is currently in review for publication. Third, we published our results concerning decontamination of emergency responders exposed to foot-and-mouth disease virus. Lastly, we are currently evaluating procedures for decontamination of livestock facilities and vehicles.

Impacts
We expect that this initiative will have wide impact on policy design as governments and livestock producers revise their biosecurity and disease control procedures for both enzootic and exotic diseases. For example, current procedures of brushing and dipping shoe soles of airline passengers that have visited livestock facilities in foreign countries in 1% Virkon S were found to be ineffective; yet, the novel protocol of brushing shoe soles, wiping soles with a cotton towel soaked in 1% Virkon S, and drying soles with paper towels disinfected shoes at least 80% of the time. Continuation of applied biosecurity research will immediately begin to address needs of the agricultural industry to maintain a healthy and safe food supply for our nation.

We continue to evaluate biosecurity procedures to prevent the mechanical transmission of porcine pathogens. We have tested on-board tire sanitizers as an adjunct tool in vehicle decontamination during the summer and fall seasons and will continue with the project this winter. We have evaluated our ability to trace State Fair animals in the case of a disease outbreak originating from the fair. Finally, we have evaluated procedures for decontamination of airline passengers that have visited livestock facilities in countries outside of the Unites States. We are currently evaluating procedures for decontamination of livestock facilities.

Impacts
We expect that this initiative will have wide impact on policy design as governments and livestock producers revise their disease control procedures for both enzootic and exotic diseases. The research will immediately begin to address needs of the agricultural industry to maintain a healthy and safe food supply for our nation.

We continue to evaluate biosecurity procedures to prevent the mechanical transmission of porcine pathogens. We have completed the second project testing biosecurity procedures to prevent mechanical transmission of foot-and-mouth disease by people. We are currently testing on-board tire sanitizers as an adjunct tool in vehicle decontamination.

Impacts
We expect that this initiative will have wide impact on policy design as governments revise their disease control procedures in the wake of criticisms surrounding the handling of the 2001 foot and mouth disease outbreak in the United Kingdom and post September 11 terrorist threats. The research will immediately begin to address needs of the agricultural industry to maintain a healthy and safe food supply for our nation.

Progress 10/01/01 to 09/30/02

Outputs
Biosecurity procedures to prevent transmission of the U.K. 2001 strain of foot-and-mouth disease virus by emergency responders were tested in a collaborative project between Purdue University and Plum Island Animal Disease Center. Showering and donning clean outerwear was necessary to prevent transmission to both pigs and sheep. Downtimes were not needed. We expect that results reported in this study will have wide impact on policy design as governments revise their foot-and-mouth disease control procedures in the wake of criticisms surrounding the handling of the 2001 outbreak in the United Kingdom. For example, elimination of downtimes could decrease the number of essential personnel needed to contain an outbreak because personnel could move more efficiently from farm to farm. Biosecurity procedures to prevent transmission of E. coli by people were tested in a collaborative project between Purdue University and Iowa State University. Again, showering and donning clean outerwear was necessary to prevent an animal caretaker from transmitting E. coli from sick pigs to healthy sentinel pigs. Downtimes were not needed. These results will assist pork producers in developing farm specific biosecurity protocols. Decontamination protocols for tail clippers during pig processing was tested. Wiping the clipper with a clean cloth was more effective than dipping the clipper in disinfectant. Sanitizing pig processing instruments is important because unclean tools can spread disease among litters of pigs or cause joint infections in individual pigs.

Impacts
We expect that results reported in these studies will have wide impact on policy design as governments revise their foot-and-mouth disease control procedures in the wake of criticisms surrounding the handling of the 2001 outbreak in the United Kingdom and as individual pork producers revise their farm biosecurity protocols.
