Bio-Security Proficiencies Program
for Young Producers
Improving practices to mitigate
disease transmission and
associated financial risks through
experiential learning.

Bio-Security: A National Issue
 National and state agencies/institutions have identified
bio-security in animal agriculture as a high priority.
o USDA: Long-term goal of safeguarding animal production
industry.
o CDFA: Focus on whole-farm approach to herd health
management through risk assessment, prioritization, and
action; professional development and education materials.
o UC ANR: Strategic Initiatives: safe and secure food supplies;
managing endemic and invasive pests and diseases.
Bio-Security and Backyard Operations
 Backyard flocks and herds are bio-security risks.
 Small producers (e.g., hobbyists; non-commercial)
represent a risk to commercial agriculture (e.g.,
2002-2003 Exotic New Castle outbreak).
 Improving bio-security practices among backyard
operations is critical to prevent the introduction or
reintroduction of economically important diseases.
4-H Animal Science
 Approximately 30,000 youth participate in 4-H Animal
Science projects annually in California; nationally, this
number exceeds 2,300,000.
 4-H Animals, particularly livestock, are commonly
shown at public fairs and exhibitions (average = 2.5
per season).
 4-H Animal Science project animals (livestock) are
most commonly kept as part backyard herds (66%).
 Average “backyard herd” size = 8.6 animals; same or
mixed species.
Bio-Security Risks at Public Venues
 Data from State Fair and eight county fairs in north
central California revealed disease transmission
risks associated with exhibition practices (Smith &
Meehan, 2012). Risks include:
o Visitor Interactions
o Animal Pens (e.g., water, tools, bedding,
vectors/vermin, food)
o Wash Racks
o Judging Arenas
Public Venues: Disease Outbreaks
 2012. Influenza A (H3N2) and variant (H3N2v) viruses at county
fairs in Midwest (e.g., OH, IN); swine and swine exhibitors
affected; swine exhibitions canceled at 2012 Indiana State Fair.
 2011. Fifty-four horses potentially exposed to equine herpes
virus (EHV-1) at Western National Championship cutting horse
competition in Ogden, UT. In California, 12 confirmed cases of
EH Myeloencephalopathy among horses that participated in
competition; five counties; one horse euthanized.
 2008. Twenty-four of 133 dairy cattle housed in one barn
contracted malignant catarrhal fever and died; source of the
virus was infected lambs owned by youth exhibitors.
Bio-Security and Youth Education
 University of California Division of Agriculture and
Natural Resources (UC ANR) Strategic Vision 2025
(http://ucanr.edu/files/906.pdf).
 Guiding document to help address wide range of new
and existing challenges in California.
 Nine Strategic Initiatives for the 21st Century.
o Initiative to Ensure Safe and Secure Food Supplies
o Initiative for Managing Endemic and Invasive Pests and
Diseases
o Initiative to Increase Scientific Literacy
Bio-Security and Youth Education
 Curriculum research, development, and testing;
educator professional development.
 Relevant curricula:
o Bio-Security in 4-H Animal Science* (Smith, M.H., Meehan, C. L. et
al. 2011) (https://ucanr.org/freepubs/freepubsub.cfm?cat=36&subcat=12)
o Pre-Harvest Food Safety in 4-H Animal Science* (Smith, M.H.,
Meehan, C. L. et al. 2011) (in press)
o Youth Development through Veterinary Science* (Smith, M.H.,
Meehan, C. L. et al. 2009) (http://anrcatalog.ucdavis.edu/Items/8372.aspx)
*Funded by grants from UC ANR, CDFA, and USDA Formula Funds
4-H Bio-Security Proficiencies*
 Build upon and augment 4-H curricula.
 Introduce opportunities to develop advanced
problem-solving skills.
 Enhance youth scientific literacy through the
authentic application of knowledge and skills.
 Address UC ANR Strategic Initiatives.
*Funded through a grant from CDFA; supplemental activities and outcome testing
funded through a grant from the Western Center for Risk Management Education at
Washington State University.
Bio-Security Proficiencies in 4-H
 Sequence of five proficiency levels; scaffold
knowledge and skills.
 Promote the acquisition of knowledge and skills
through the Experiential Learning Cycle that includes:
o Active engagement through “hands-on/minds-on”
experiences (Confrontation).
o Opportunities to reflect on experiences (Assimilation).
o The application of knowledge and skills to authentic
situation (i.e., using new knowledge and skills to make
decisions and solve problems) (Accommodation.)
Learning: A Continuous Process
Grounded in Experience
 Knowledge is continuously derived from and tested out
in the experience of the learner (Kolb, 1984, p. 27).
 Learning is an ongoing process that, by its nature, is a
tension- and conflict-filled process.
 At one extreme, learning involves active engagement;
at the other extreme, it revolves reflective
observation.
The Learning Cycle and
Knowledge Construction
 Confrontation: The process of active engagement should create
cognitive dissonance (the “groan zone”), violating expectations
and creating some level of doubt and uncertainty for learners.
 Assimilation: Reflection provides opportunities to challenge
prior understanding and address skepticism related to new
understanding. Learning is a social endeavor; it is important to
reflect from multiple perspectives.
 Accommodation: The use of new knowledge and skills to make
decisions and solve problems in authentic settings. Allows
learners to adjust and solidify their new/revised understanding.
This helps make “learning last.”

Detailed Risk Mitigation Plan
(Vector/Vermin)
Describe the Risk:
 Many flies, mosquitoes, and mouse droppings visible in the barn, feed shed, and
surrounding yard. Water collects on the ground near the spigot on the outside of
the barn and near the barn entrance after it rains. Standing water could be a
breeding area for insects.
Describe your Detailed Plan to Reduce the Risk:
 Set mouse traps in feed shed.
 Hang fly paper every 25 square feet in barn.
 Hang bug zapper near barn.
 Patch holes in feed shed.
 Fix water spigot to stop leaking.
 Level ground and place gravel near barn entrance to prevent pooling of
water after rain.
Detailed Risk Mitigation Plan
Describe the Investment Required (include money, supplies, help
from friends or parents, etc.) :
1. Need a ride to the hardware store to get supplies.
2. Need adult’s help to fix the spigot.
3. 4 mouse traps = $10
4. 8 fly paper traps = $5
5. Bug Zapper and extension cord = $35
6. Scrap wood and nails = free
7. Gravel (25 square feet x 2 inches deep) = $40
8. Plumbing supplies = TBD
Detailed Risk Mitigation Plan
Describe your Expected Outcomes:
 I expect that there will be an immediate reduction in the amount of flies in the barn,
but I will need to replace fly paper on a regular basis. The bug zapper might be more
effective, but I’m not sure if we can run an extension cord safely to the barn.
Describe the Potential Challenges of this Plan:
 Mouse dropping should decrease if we can trap them or cause them to move away if
we prevent access to the feed shed by patching holes. If we can’t trap them, they may
just move into the barn to access the feed there. Placing traps in the barn will be
challenging because I don’t want the sheep to be able to access them. Maybe we can
find some out of the way areas to place additional traps.
 If we can eliminate the standing water, we should be able to reduce the number of
mosquitoes. Do not know how expensive it will be to fix the spigot.
Proficiency Level 4: Public Presentations
 Six community presentations were delivered and
attended by 140 adult community members.
o Voluntary survey was completed by 63 attendees.
 Of the presentation attendees, 41% were active in
animal agriculture either as producers or hobbyists.
 Other attendees included parents of 4-H participants,
local government representatives, 4-H staff, fair board
members, and representatives of agricultural
associations.
Attendee Survey Results
Survey respondents from public presentations reported:
 Improved understanding of the modes of disease transmission.
 Improved in knowledge of critical control points in disease
spread.
 Increased understanding of the financial risks related to
biosecurity practices among young producers.
Of those who identified themselves as active in animal agriculture,
95% reported that the information presented by the youth was
directly applicable to their own practices.
Proficiency Level 5 Siskiyou County Fair
Cleaning and Disinfecting
 All pens, tie stalls, wash
racks and scales were
cleaned and disinfected
with a bleach solution that
was sprayed on all
surfaces.
Education and Outreach
 Participants spoke with fair
attendees and other youth
regarding bio-security
practices.
