The Florida Department of Agriculture and Consumer Services (FDACS) is urging veterinarians, livestock producers and animal health experts to stay vigilant about the recognition of new world screwworm signs and symptoms as a threat to spreading to the United States.
According to FDACS, screwworms can pose a threat to American livestock, wildlife, livestock, and animals involved in the US food system, particularly beef and dairy cows. This threat is most severe for states with warm climates and rich animal populations such as Florida.
In light of the spread of New World screwworms from Panama to southern Mexico, the USDA had halted imports of live cows, horses and bison from Mexico to the United States as of Sunday.
To help you understand this insect, experts at the University of Florida explain what screwworms are in the new world, why the US faced previously, and how to recognize signs of screwworm infection in animals.
What are the new world screwworms?
The New World Screwworm is a type of fly scientifically known as Cochliomyia hominivorax. The maggots are a major concern as they eat the live meat of warm-blooded animals.
Maggots are in the stage of fly larvae. It is a small insect-like insect that hatches from a fried egg. Unlike most maggots that eat dead tissue and help break down, New World screwworm Maggo eats live healthy tissue. Using existing wounds as a point of entry, they can burrow into live animals with existing open wounds, causing damage to serious, sometimes fatal animals, said Andrew Short, chairman of the UF/IFAS ministry.
Screw insects can invade livestock, pets, wildlife, sometimes birds, and in rare cases people.
All warm-blooded animals are at risk of screwworm infection, especially if they have recently exposed wounds or have just undergone surgery.
When was the last time the US had a screwworm outbreak?
The new world’s screwworms were in the United States even before the Civil War until it was eradicated in 1966, Short said.
In 2016, the infection spread to a population of key deer in Florida Key. The infection continued until early 2017, when sterile fly treatments were successful in eliminating screwworms from the environment.
Currently, there are no reports of new world screwworms in the US

Can screwworm infections be treated?
Yes, screwworm infections in the new world are treatable. In humans and domesticated animals, treatment usually involves medical or veterinary procedures to physically remove the larvae. In wildlife, control efforts focus on eliminating screwworm flies from the environment.
How do you remove screwworms from the new world of the area?
Eradication of new world screwworms is accomplished by releasing sterile flies into the environment, sterilized by the environment, combining with local new world screwworm populations, further stopping breeding. The new world’s screwworm population dies.
What are the symptoms of screwworm infection in the New World in animals?
Symptoms in animals with screwworm infections include irritating behaviors, particularly wounds, head shaking, biting with open wounds, smelling tissue disruption, wound rabbits, large red bumps from fly strikes, signs of no-feeding depression, reduced milk production, and isolation from the rest of the herd.
Early symptoms can be difficult to see, but the most obvious sign is a change in the appearance of the wound, which increases and deepens the wound. According to FDACS, there may be a bloody discharge from the hospital with a smell.
Dr. Fiona Mohnsel, clinical associate professor of UF Veterinary Medicine, said that animals and livestock owners who suspect a screwworm infection should isolate the animals and contact the veterinarian immediately. Concerns should also be reported to the state veterinary office. According to Mounsel, owners should not first contact the veterinarian or state veterinarian office, and not first contact the veterinarian or state veterinarian office, and not treat the veterinarian or state veterinarian office.
Any animal can be infected, but animals that spend most of their time outside, especially those that give birth outside, are at great risk due to open wounds. To prevent this, dry out and cover the wound and report any signs of illness to your veterinarian.
How can I report a new world of screwworm infection?
In an FDACS press release, Dr. Michael Short, a veterinarian from Florida, says early detection and reporting is essential.
“The earlier we catch a potential case, the more likely we will include it. We ask everyone who works with animals, whether it’s personal practice or on the ground, to reaffirm any uncommon or wounds that don’t heal as expected,” he said.
Please contact us to report cases of New World Screwworm infection in livestock and pets.
To report a suspected wildlife screwworm infection, call the Florida Fish and Wildlife Conservation Committee (FWC) at 888-404-FWCC (3922) or email the Wildlife Health Team [email protected].
