Farm Biosecurity
Risk Assessment
How well are you protecting your live assets—your
livestock—from diseases currently not found on your premises? This
assessment will help you find out. The questions are designed to
be answered from a farmer’s perspective. Although they were written
with a dairy farm in mind, almost all of the questions apply across all
types of livestock farms. Select the option that most closely reflects
your current farm management practices. Be honest! Then use
the score card to help assess your farm’s risk.
Animal health, animal additions, commingling
with other herds
-
How many of the following practices are part
of your herd health program? We follow protocols for:
-
colostrum management,
-
feeding management,
-
forage quality and ration formulation,
-
manure handling (with special attention to
avoiding contamination of feed alleys and feeding equipment),
-
stall comfort and cleanliness,
-
air movement (cooling in summer) and ventilation
(especially in winter),
-
milk quality monitoring, and
-
routine vaccinations.
-
We monitor compliance with all protocols.
-
We review our protocols with our veterinarian
at least annually.

-
Knowing that stress reduces the ability of
animals to resist diseases, how many of the following practices do you
enforce?
-
We maintain a regular daily routine (e.g.
of feeding and milking).
-
We maintain a consistent ration (e.g., test
forage dry matters regularly and after any precipitation).
-
We maintain adequate nutrient levels in rations
(e.g., fiber for cows).
-
We minimize switching animals between groups
or rations.
-
We minimize stacking of stressful events (e.g.,
multiple vaccines on same day).
-
We handle all animals calmly and quietly.

-
How many of the following ration management
practices do you use to maximize animal health?
-
We analyze all of our forages.
-
We use a ration balancing program ourselves
or through our nutritionist.
-
We regularly monitor lameness, body condition
scores, and rumination activity (or have our veterinarian or nutritionist
do this).
-
We feed a total mixed ration (TMR) and minimize
the potential for ration sorting.

-
How well do you prevent contamination of feed
by manure with equipment?
-
The same equipment (dump buckets or shovels)
may be used for either feed or manure, but is usually cleaned in between.
-
The same equipment is used for both feed and
manure only if cleaned well (after being contaminated by manure).
-
A separate bucket or skid steer is used for
pushing feed and scraping manure. Shovels are dedicated to use with
either feed or manure.
-
How well do you prevent contamination of feed
by manure with wheel or foot traffic?
-
Feed delivery equipment never crosses routes
contaminated by manure. People working with animals never step in
feed mangers with boots contaminated with manure.
-
Feed and manure handling traffic is kept separate
as much as possible. Pass throughs or gates make it easy to avoid
stepping in feed if entering or leaving cow pens in a freestall.
-
Feed and manure handling traffic uses the
same paths or crosses paths. People walk through feed mangers to
cow alleys and vice versa.
-
How well are instruments for jobs such as
hoof trimming and dehorning cleaned and disinfected (sanitized)?
-
Not cleaned or disinfected between animals.
-
Cleaned (but not disinfected) between animals.
-
Cleaned and disinfected between animals.
-
Thoroughly cleaned and disinfected between
animals.
-
How many times are the same rectal sleeves
and needles used?
-
Sleeves are changed between groups or if blood
is seen. A different needle is used for each vaccine or product.
-
Sleeves and needles are used only once with
one animal.
-
One can do all or most of the herd.
-
How are replacement or new animals (including
bulls) for your herd acquired?
-
From auctions or sale barns, not tested and
not isolated upon arrival.
-
From auctions or sale barns, tested after
purchase and briefly isolated (for less than 2 weeks).
-
Only from herds of known health status, with
screening tests and less than 30 days of isolation.
-
Only from herds of known health status, with
screening tests and a minimum 30-day-isolation-period.
-
No animals are purchased; we maintain a closed
herd.
-
How are replacement heifers for your herd
raised?
-
Our heifers are sent to another facility for
some period of time and commingled with animals from other herds.
-
Our heifers are sent to another facility for
some period of time, but are not commingled with animals from other herds.
-
Our heifers, if sent to another facility for
some period of time, are isolated from the rest of our herd upon their
return.
-
Alternatively, we raise all our own heifers
on our own facilities and do not raise heifers born on other farms.
-
Our heifers, whether we raise them on our
farm or through a contract raiser, are tested for persistent infection
with BVD and vaccinated according to a regular protocol.
-
If you show animals, how many of the following
steps do you take to minimize your herd’s health risk?
-
Our show animals have current health certificates.
-
Our herd’s vaccination status is current.
-
We use our own trailer (or one that has been
cleaned and disinfected).
-
We use our own equipment for grooming, feeding,
and milking.
-
We prevent nose-to-nose contact between our
animals and those from other farms.
-
We bring home the same animals we took to
the fair (no new ones!).
-
We isolate returning animals.

Visitors and agri-service personnel
-
Where do farm visitors (anyone not employed
by the farm) park?
-
Wherever they want.
-
In a designated area by the main entrance.
-
In a designated area by the main entrance,
away from livestock, and without driving through manure hauling or feed
delivery lanes.
-
Like C, and low-risk visitor parking is set
apart from medium- and high-risk visitor parking.
-
Where do farm visitors enter?
-
Wherever they want; multiple entrances may
be used.
-
Usually through the main entrance, although
it is not marked as the desired entry point.
-
Usually through the main entrance, which is
clearly identified, although some visitors (especially medium-and high-risk
visitors) enter wherever they want.
-
All visitors enter through a single, clearly
marked entrance; we have a visitor log that some visitors sign.
-
All visitors enter through a single, clearly
marked entrance; and all sign our visitor log.
-
Do you restrict visitor access based on the
risk they present?
-
No, not really.
-
We posted a biosecurity sign a couple years
ago and figure that is enough.
-
We turn away visitors who have been outside
of North America in the past five days.
-
We know what risk our visitors present and
restrict their access to parts of the farm accordingly, e.g. cattle hauler
cannot enter barns.
-
What do farm visitors wear?

You don’t care as long as it’s not obscene.
-
Boots and outerwear that appear clean.
-
Boots and outerwear that appear clean; they
may pass through a boot sanitizer mat or put on booties that are available.
-
Boots and outerwear that appear clean; they
must sanitize their boots upon entry or put on plastic boot protectors;
plastic booties are disposed of on your premises.
-
Boots and coveralls (or plastic booties) that
you provide for use only on your farm. Boot wash stations, placed
throughout the facility at entrances/exits from high-risk areas, are used
by high-risk visitors.
-
Whose equipment do visitors use?
-
Their own—potentially used at other livestock
operations (halters, nose-leads, clippers, dehorning or hoof trimming equipment,
etc.) and not necessarily cleaned and disinfected.
-
Their own—potentially used at other livestock
operations, but clean.
-
Their own—cleaned and disinfected prior to
use on our farm.
-
Some of their own plus some provided by our
farm—all clean.
-
Only equipment provided by our farm.
-
What animals can visitors come in contact
with on your farm?
-
Only veterinarians and other animal service
providers are allowed contact with any animals. And they organize
their work from clean to dirty, youngest to oldest, healthy to sick, in
addition to wearing proper protection (disposable gloves, coveralls, etc.).
-
Only veterinarians and other animal service
providers can contact our high-risk animals—young stock, periparturient
(around birthing), or sick animals.
-
Most visitors can contact only adult, healthy
animals.
-
Most visitors can contact only healthy animals.
-
Any visitor can contact any animal.
-
When you visit other farms, what do you do
to ensure the health security of both of your herds?
-
I don’t think twice to drive right over in
my farm clothes and boots to borrow a tool or stop in to chat.
-
I wear clean clothes and boots (not your farm
work boots) and stay out of feed and manure on the farm I am visiting.
-
I wear clean clothes and boots and stay out
of feed and manure on the farm I am visiting. I clean and disinfect
my boots before leaving.

Alternatively, our herd has regular access
to a pond or stream that is not protected from wildlife.
-
Our herd drinks water from sources that are
protected from manure (of livestock or wildlife) as much as possible.
-
Our herd drinks water from sources that are
tested semiannually.

We use appropriate insecticides (tags, pour-ons)
and premise products (including fly tape) as-needed. If resistance
develops, we change products.
-
We have an integrated pest management program
including insecticides, parasitic wasps, bedding and manure management.
We follow practices to prevent the development of insecticide resistance.
-
We’re doing what we’ve always done, but it
doesn’t seem to be working so well.
