Biosecurity• Biosecurity refers to management strategies that lessen

biological risk – a biological risk is something that can cause disease in other living things• Small and large 4-H animals depend on their human owners to

provide them with medical care, safe, clean housing, food and water.• Biosecurity practices minimize the spread of diseases or pests

in 4-H project animals and on farms.• Many biosecurity practices are “common sense”- HOWEVER

they must be consistently followed to reduce risk.

Be SICK Smart• S-anitize- This PowerPoint will tell you more

about how and why to sanitize• I-solate- Any sick animal and animals

returning from a fair/show for 14 days• C-ontact- Prevent contact at fence lines and

animal nose touching• K-now- What “Normal” is – including: T.P.R.,

coat, behavior, food consumption etc…AND

April 19, 20234

More to “K-now”

• Know what proper and appropriate care is.• What are a healthy animals’ needs in your region?• What are appropriate feed rations? Spatial needs?

Vaccinations? Deworming? And other routine health maintenance?

Sanitization is Part of Your Biosecurity Plan

•What is Sanitizing?•Cleaning is removing organic materials

from objects.•Disinfecting is to destroy

microorganisms on objects.• Sanitizing is simultaneously cleaning

and disinfecting objects.

April 19, 20236

What are we Sanitizing for?•Microorganisms! • They are also called GERMS, when they

cause infections diseases in people or animals•Microorganisms can’t be seen by the

naked eye- some even require an electron microscope to be viewed!

April 19, 20237

Microorganisms•Most are considered living organisms and

millions of them are all around us all the time.•Bacteria, and many protists (i.e.: algae)

and fungi (i.e.: mushrooms) are microorganisms.•Viruses are also Microorganisms

April 19, 20238

Viruses•Viruses are a challenge to science. Some

scientists think they are living organisms and should be considered microorganisms. However, viruses cannot grow or reproduce outside a host cell. For this reason, some scientists argue they are not living organisms.

April 19, 20239

Viruses and animals

• For example, rabies is caused by a virus. • It is important to know which viruses

may infect your type of animal and have a plan for prevention • In your plan, it’s important to reduce

exposure to vectors such as flies or mosquitos, since they are major carriers of viruses.

April 19, 202310

Viruses and humans

• For example, the “common cold” (known as Rhinovirus) is caused by a virus. • Since viruses are a major cause of

disease and illness in humans and animals, we vaccinate.

April 19, 202311

Vaccines

•Vaccines are used to combat viruses in humans and animals. Some human diseases we vaccinate for are mumps, measles, and chicken pox.

April 19, 202312

Vaccines

• Your local veterinarian or county Extension Livestock Agent can provide information on developing a vaccination schedule for your species of animal.

Other “Germs”• Bacteria are one-celled creatures that get nutrients from their

environment. In some cases that environment is a human’s or animal’s body. In people they cause infections such as strep throat, pneumonia and tuberculosis.

April 19, 202314

Other “Germs”• Fungi are multi-celled organism. Fungi cannot make their own

food; instead they get their nutrition from plants, people and animal. Athlete’s foot and ringworm are caused by a fungi. Yeast is a useful fungi. What other fungi do we eat?

April 19, 202315

Other “Germs”• Protozoa are one-celled organisms that need a moist

environment to survive. In humans protozoa cause intestinal infections that lead to diarrhea and nausea.

April 19, 202316

Microorganisms• They aren’t ALL bad! Many bacteria are useful to

humans!• Yogurt is produced by the fermentation of milk. Two of

the bacteria found in yogurt are Lactobacillus bulgaricus and Lactococcus thermophilus. These are lactose fermenting bacteria that produce lactic acid from the lactose in milk. • Some help with digestion, destroy harmful organisms

or assist with decomposition in landfills.

How do Germs spread?

See the Handouts accompanying your Glo-Germ kit

The Glo- Germ lesson plan lists these 4 ways:• Fecal-oral contact (i.e. Hepatitis A)• Direct/close contact (i.e. Lice)• Blood contact (i.e. hepatitis B, HIV/Aids)• Respiratory/airborne contact ( influenza, colds)

April 19, 202318

How do Germs spread?

The Minnesota Food Safety Center Handout lists 5 Ways the human hand spreads germs:• Nose, mouth or eyes to hands to others• Hands to food• Food to hands to other food• Animals to people • Infected child to hands of other children

April 19, 202319

To fight GERMS for our animals: Sanitize

Sanitizing = Cleaning + Disinfecting•Clean= remove all organic material•Disinfecting= Destroying microorganisms

April 19, 202320

What do we sanitize?• Any equipment used on sick

animals• Any equipment that comes in

contact with an animal’s skin & blood after each use: hoof knife, clippers, tattoo pliers, ear taggers, ear notchers, dehorners• On a regular schedule- waterers

and feed troughs• Nursing bottles and buckets before

each feeding

April 19, 202321

What do we sanitize?

• Vehicles to be used to transport animals & use clean bedding• All equipment, halters & gear taken to a fair/show upon return• Animal housing between animals and isolation areas• Any equipment before sharing and when it is returned• Our own boots!

April 19, 202322

Bleach- Sodium hypochlorite• Should be used by adults or with adult supervision.• Wear protective equipment- read the label on the bottle!• Remove all animals from they area- bleach can irritate their

mucus membranes too.• Dry the surface before using bleach- properly diluted bleach on

a damp/wet surface is diluted further.• Be patient- bleach solutions require a full 10 minutes of

contact time to ensure complete disinfection.• Rinse and dry before returning equipment to use or animals to

an enclosure.

April 19, 202323

Bleach- Sodium hypochlorite

Daily use formula 5.25% sodium hypochlorite or 1:32 solution• ½ cup bleach per gallon of waterOR• 1 ounce of bleach per 32 ounces of water in a

spray bottle• Fresh solutions should be prepared daily for

the most effectiveness

April 19, 202324

Bleach- Sodium hypochlorite

• For periodic deep cleaning use a 1:10 concentration of bleach• Remove animals from the area• Use protective equipment• 1 ½ cups bleach per gallon of waterOR• 3 ounces of bleach per 32 ounces of water

April 19, 202325

• YOU can carry and spread germs too!

• Use the lessons in the Glo Germ kit to practice good hand washing procedures.• Apply what you learn about

ensuring hands are clean to your animal husbandry routines

Let Glo Germ Light the Way!

April 19, 202326

Your Glo Germ kit includes:• Glo Germ Gel• Glo Germ Powder • An Ultra Violet Flash Light • Hand washing lesson plans

and copy pages for grades K- 6

You will need to have: • A Watch with a second hand• Warm water & soap• Paper Towels

Glo Germ Kit

April 19, 202327

• Ask for a volunteer• Place 2 drops gel or a light

sprinkling of power on each hand.• The volunteer should rub

their hands together.• The volunteer should wash

their hands with soap.• Use the Ultra Violet light- Can

you see any Glo Germs?• Continue with the lesson in

the Trainers Manual

Glo Germ Gel or Powder Lesson

Draw a quadrant on the bottom of each Petri Dish before mixing and pouring the nutrient agar.Try this experiment. Select a feed bin, water trough or other item to study. Sample it 4 times:1- before you start to clean.2- after you clean.3- after you disinfect with 1:32 bleach solution4- after you disinfect with 1:10 bleach solution

Extend the Learning- Put 4 Samples into 1 Petri Dish

April 19, 202333

• Form a hypothesis about the results you will get in each of the 4 quadrants on the Petri Dish.• Once you have results,

compare them to your hypothesis.

• Form another hypothesis based on the information you learned and test it too!

Before you begin…think like a scientist!
