Biosecurity practices focus on the prevention of importing diseases onto a farm. The benefits to
animal welfare, product quality, and farm profitability are well recognized and have been known for
many years. Despite the obvious benefits of effective biosecurity programs most dairy farms have few
if any procedures in place to protect their herds. Far too many dairy producers view biosecurity as a
bewildering array of infectious agents, expensive tests, and time consuming animal handling schemes.
In general much of the emphasis on biosecurity has focused solely on the animal and the infectious
agent (s). An important component of biosecurity that has been far to often overlooked is the
importance and influence of the environment. Facilities and design can have a huge impact on the
spread or prevention of disease.
