Biosecurity is not a new issue or concern for U.S. livestock operations. For years, producers have been overwhelmed with information on the importance of biosecurity. However, adoption of biosecurity programs for much of the livestock industry has been slow. Most producers employ some biosecurity practices, such as quarantining new animals, using clean needles or segregating animals by age, but they do not have a comprehensive program. Typical biosecurity plans in use today by U.S. livestock producers do not address the issues of people and traffic control.
