Biosecurity A Practical Approach
 

Summary: Biosecurity
A Practical Approach

In today's animal agricultural industries various trends are present to potentially increase
the spread and prevalence of infectious diseases in herds. Many of the diseases are of food safety
concern or of economic concern. In either case it is important to the animal industry both for
confidence in agricultural products, market share and for economic reasons to prevent the spread
of infectious diseases from farm to farm. The series of management practices that are
employed to prevent the importation of infectious agents from entering a farm is termed
biosecurity. Biocontainment is similar to biosecurity. Biocontainment is the series of
management practices that prevent the spread of infectious agents between animal groups
on a farm or the management practices designed to prevent the infectious agent from
leaving the farm.
As herd size increases and as herds are placed in more intensive housing management
systems, in many cases it is easier for infectious diseases to enter and spread throughout a herd.
In this regard relatively small and stable herds with minimal herd additions and good animal
comfort frequently have a lower prevalence of infectious disease and may have several
advantages in developing a biosecurity and biocontainment program. With the recent headlines
and concern regarding infectious disease spurred by the spread and economic devastation
