| ASI Continues Monitoring New World Screwworm Response |
| Sheep industry representatives continue to closely monitor the New World screwworm (NWS) situation, particularly the response to detections in Texas and New Mexico. ASI has been in regular communication with federal leaders at USDA’s Animal and Plant Health Inspection Service (APHIS) and the FDA’s Center for Veterinary Medicine (CVM) regarding issues that have arisen since the first detection.For details on how USDA APHIS is coordinating the NWS response, as well as information on control and prevention measures, view the USDA NWS Response Playbook. The publicly available document was developed with input from stakeholders across animal agriculture, including ASI. As with any disease threat, states may implement additional movement restrictions for animals originating from areas where infestations have occurred. Many states have already enacted restrictions on livestock movements from affected zones. For details on current restrictions, visit www.interstatelivestock.com.Some states now require animals from infested zones to be tagged prior to movement. If tagging, producers should be sure to spray the tag site with an approved product that contains 0.5% permethrin to kill and repel screwworm flies. FDA has released conditionally approved and authorized animal drug options for New World Screwworm here.
