Page 8 - MDWFP CWD Response Plan

Testing should be sufficient to detect CWD with 95% confidence if the disease exists
at a prevalence of at least 1% inside the enclosure (Appendix G). In the event of a
confirmed CWD positive within 5 miles of an enclosure, all samples collected inside
the enclosure within 3 years prior to the confirmed CWD positive will be counted
toward the sampling goal.

Captive Cervids

In addition to all above management actions, the following response actions will also be
implemented if CWD is confirmed in a captive cervid facility within Mississippi.

 The contaminated enclosure will be inspected by MDWFP staff to ensure fencing
requirements are maintained to avoid possible escapes. All gates will be secured.
Law enforcement staff will be assigned to monitor the enclosure and gates to ensure
compliance with established regulations.
 Immediately quarantine facility to ensure no cervid movement into or out of
enclosure.
 Per Miss. Code Ann. § 49-7-58.1, MDWFP personnel shall enter the enclosure and
depopulate the white-tailed deer. All cervids within the facility will be tested for
CWD. No state funds will be used to indemnify captive facility licensees or
permitees.
 Trace-back and trace-forward of live cervids and reproductive material from the
affected facility will be conducted to include a time span of at least 5 years. Captive
facilities within Mississippi that transferred cervids to or received cervids, and/or
reproductive material from the CWD positive facility will be quarantined and
inspected. The transferred deer will be sampled immediately. After the average
CWD incubation period of two years has elapsed, the herd will be sampled sufficient
to detect CWD with 95% confidence if the disease exists at a prevalence of at least
1% throughout the herd. No state funds will be used to indemnify captive facility
licensees. If records indicate that a captive cervid left Mississippi, then the final
destination state wildlife agency will be notified.
 Target sample size for any enclosure within or partially within the 5 miles of the CZ
should be sufficient to detect CWD with 95% confidence if the disease exists at a
prevalence of at least 1% throughout the zone (Appendix G).
 If CWD is initially confirmed in an enclosure, the CZ, HRZ, and BZ will be
delineated from the enclosure boundary, not the exact point of sample collection.
 The owner of the contaminated captive cervid facility will accept the responsibility of
maintaining the perimeter fence to ensure that no wild cervids are allowed to enter the
facility.
 All MDWFP and MBAH captive cervid permits issued for the enclosure will be
revoked once the enclosure is depopulated.
