L Q A & EPROGRAM

Level II

Biosecurity Lesson

WELCOME TO

Participants will be able to:• Define biosecurity• Identify major components

of biosecurity• Identify appropriate

biosecurity management practices and procedures

• Develop a biosecurity plan for their 4-H Project

Biosecurity Learner Outcomes

Lesson Outline• True or false questions (dry erase

or show of hands)

• Clearly define Biosecurity

• List diseases of concern – define them and how they are spread (blackboard, flipchart, etc.) The final list should include Avian Influenza, Johne’s, Pneumonia, Pseudorabies and Tuberculosis

• Walk through Powerpoint presentation

• Management Practice Card Activity

• Case Study Activity

• H1N1 Discussion (optional, ONLY if time permits)

Biosecurity Defined:

Set of preventative

measures taken to reduce the risk

of disease introduction or transmission

Diseases of Concern

How Are Diseases Spread?

• Diseased animals• Other animals and

pests• People• Vehicles and

equipment• Carcasses• Feedstuffs• Impure water• Air

A - RITS

The Five Components of Biosecurity

A - ASSESSMENT

What are potential points of contamination?

R - RESISTANCE

Animal’s ability to reject or contend with an infection

• Nutrition

• Stress

I- ISOLATION

Preventing contact, commingling

T – TRAFFIC CONTROL

Vehicles, people, animals, wildlife, rodents, insects

S - SANITATION

Cleaning, disinfecting, removal of organic matter

Management Practice Cards

Cleaning out a pen between groups of animals. I (Isolation)

Teaching point• Isolation refers to

prevention of contact between animals with in a controlled environment. Cleaning out pens is away to control the environment by having clean surroundings.

Clean the livestock trailer after haling the neighbor’s cow to the veterinarian T (Traffic Control)

Teaching point• Trucks and trailers can

harbor germs • Take a few minutes to

disinfect tires and the inside of your trailer between “hauls.”

Case StudyFreddy the 4-Her takes many animals to the county fair. He

shows poultry, swine and cattle. For many years the animals just came directly home from the fair and were put right back into the pens with the rest of the animals. Freddy’s dad has

since realized that animals can pass diseases between themselves when they are at the fair. The animals are in contact with other animals while in the show ring, on the wash rack or in

the watering areas. Freddy’s dad has since decided that they should have a plan in

place to limit the possibility of passing the diseases like ringworm or warts to other animals on the farm once the fair

animals return home.

Using the A-RITS formula, what are some management practices Freddy could use?
