The proposed rule is being developed in order to protect the cattle of Florida, manage disease outbreaks and ensure market access for cattle and bison moved to other states. Animal identification is critical to prevent and control dangerous transmissible diseases of such livestock. Identification and record-keeping enable producers and regulatory officials to trace the movement of diseased animals and more quickly and efficiently contain disease outbreaks. Difficulties in identifying the source of individual animals and their cohorts increase the scope and costs of investigations and response. This rule will provide for identification of adult cattle and bison moving within Florida just as a recently published federal rule does for cattle and bison moving across state lines. This rule will not only support disease control measures but also ensure marketing capability as other states adopt similar requirements. Impact of Rule: This rule will require producers to identify adult cattle prior to movement in order to support disease tracing and control efforts. This rule will not change existing rules but supports those rules which require official identification of cattle.
