Following Additional New World Screwworm Detections in Texas and New Mexico, Commissioner Wilton Simpson Strengthens and Extends Emergency Rule Protecting Florida
Updated Rule Expands Import Restrictions, Prohibits Rescue and Shelter Animal Imports from Infested States, and Extends Temporary Moratorium Through June 12, 2026
TALLAHASSEE, Fla. – Following additional detections of New World Screwworm (NWS) in Texas and New Mexico, Florida Commissioner of Agriculture Wilton Simpson announced today that the department will be further strengthening Florida's already aggressive efforts to prevent the reintroduction of the destructive pest into the state by implementing Emergency Rule, 5CER26-7.
The updated emergency rule expands restrictions on animal imports from affected areas, prohibits the importation of rescue and shelter dogs and cats from states with confirmed NWS detections, revises the definition of "infested zones" to any county with a confirmed NWS detection and its surrounding counties, and extends Florida's temporary moratorium on the importation of warm-blooded animals from affected areas through June 12, 2026.
"New World Screwworm remains an ever-changing situation, and Florida's response will continue to evolve as the facts on the ground evolve," said Florida Commissioner of Agriculture Wilton Simpson. "We will respond based on facts, not fear. But we will also continue to be the most aggressive state in the nation when it comes to protecting our livestock, pets, wildlife, people, and agricultural economy from this threat. As additional detections have been confirmed in Texas and New Mexico, we are strengthening what are already some of the strongest protections in the country to keep Florida prepared and protected."
The Emergency Rule was initially issued on June 5 following the detection of New World Screwworm in Texas. Today's updates further strengthen those protections based on the latest information available from animal health officials and federal partners.
The updated emergency rule imposes the following temporary restrictions:
High-Risk Areas
- All warm-blooded animals originating from a high-risk area and entering Florida must be accompanied by an Official Certificate of Veterinary Inspection (OCVI), valid for five days from the date of inspection, documenting that all animals listed have been inspected and found free of contagious and infectious diseases and pests, including NWS.
- No alternative movement documents will be accepted in lieu of an OCVI.
- The OCVI must include the statement: "All animals listed on the OCVI have been inspected and are free from screwworm larvae infestation."
Counties with Confirmed NWS Detections and Surrounding Counties
- No imports of warm-blooded animals originating from a county with a confirmed NWS detection or any surrounding county until June 12, 2026.
- Following June 12, all warm-blooded animals originating from a county with a confirmed NWS detection or any surrounding county and entering Florida must receive an FDACS Certificate of Animal Movement with a prior permission number obtained at least two days before arrival.
- The FDACS Certificate of Animal Movement will require:
- An Official Certificate of Veterinary Inspection (OCVI); and
- Documentation that all animals have been treated with an effective prevention/treatment for NWS.
Rescue and Shelter Animals
- Rescue dogs, rescue cats, shelter dogs, and shelter cats originating from states with confirmed NWS detections are prohibited from entering Florida until further notice.
Although there have been no detections of New World Screwworm in Florida, FDACS continues to coordinate closely with the United States Department of Agriculture, state animal health officials, veterinarians, livestock producers, and wildlife partners to monitor developments and respond as needed.
To be clear, New World Screwworms do not infest meat, fruits, vegetables, or other food sources, and thus pose no risk to the food supply.
The New World Screwworm is a destructive parasitic fly whose larvae feed on the living tissue of warm-blooded animals. While eradicated from the United States decades ago, recent detections in Mexico and the southern United States have prompted heightened vigilance and preventive measures.
FDACS encourages veterinarians, livestock owners, animal shelters, rescue organizations, and animal health professionals to remain vigilant and immediately report suspected cases.
FDACS is also emphasizing the importance of early detection and reporting. FDACS has created resources to help animal owners and the veterinarian community identify signs of screwworm infestation, which typically appear as slow-healing wounds containing larvae. Prompt reporting is critical to protect both animal health and the state’s agricultural economy.
Anyone who suspects the presence of New World Screwworm should contact FDACS at (850) 410-0900 during business hours or 1-800-342-5869 after hours, email RAD@FDACS.gov, or visit FDACS.gov/NWS for additional information and reporting resources.
To report sick or injured wildlife, including a suspected screwworm infestation, call the Florida Fish and Wildlife Conservation Commission (FWC) at 1-888-404-FWCC (3922) or email the Wildlife Health Team at WildlifeHealthTeam@MyFWC.com.
Since the threat of New World Screwworm began moving closer to the United States, Commissioner Wilton Simpson and FDACS have taken a series of escalating actions recently to protect Florida's livestock, pets, wildlife, and agricultural economy:
-
May 12, 2025: FDACS launched a statewide awareness and preparedness campaign, urging vigilance and expanding outreach to veterinarians, livestock producers, shelters, and animal health professionals.
-
April 24, 2026: Commissioner Simpson issued an emergency rule imposing enhanced import requirements on animals from high-risk areas.
-
June 5, 2026: Commissioner Simpson issues Emergency Rule 5CER26-6 following USDA confirmation of New World Screwworm in Texas.
-
June 10, 2026: Commissioner Simpson issues Emergency Rule 5CER26-7, that strengthens and expands emergency protections, including restrictions on rescue and shelter animals from affected states and expanded geographic import controls.
-
June 10, 2026: Commissioner Simpson requested and received approval for an amendment to the current Executive Order issued by Governor DeSantis on the impacts of winter weather, droughts, and wildfire risks.
Commissioner Simpson added, “I’m grateful to Governor DeSantis for supporting swift action and providing us with as many tools in the toolbox to combat this threat to Florida.”
