New World screwworm

Track confirmed New World screwworm infestations in Texas and learn what the flesh-eating parasite is, which animals are at risk, how it spreads, what symptoms to watch for and what officials are doing to contain the outbreak.

Texas Biomed plans on partnering with Flyttr, formerly known as Oxitec, a private biotech company based in England that specializes in pest management.

As of Thursday, Texas has confirmed 19 cases of New World screwworm, a flesh-eating parasite that could cause nearly $2 billion in annual economic losses. Wildlife experts warn that deer may be especially vulnerable because there is no proven way to treat them in the wild.

Several drugs to treat animals during the Texas screwworm outbreak have been approved by the Food and Drug Administration, including a generic medication for household pets such as dogs and cats.

The New World screwworm has crossed into Texas from Mexico, threatening livestock, wildlife and pets. Human infections are rare, but officials warn the parasite's spread poses a growing challenge for communities across South Texas.

Texas Agriculture Commissioner Sid Miller says the screwworm will continue to spread unless officials adopt a more aggressive response. Also, energy economist Ed Hirs says Texas oil producers are not significantly increasing production despite higher oil prices.

Eleven cases have now been confirmed in Texas as officials expand surveillance efforts, release millions of sterile flies and mobilize resources to stop the flesh-eating parasite from spreading.

Texas A&M AgriLife livestock entomologist Sonja Swiger discusses the risks New World screwworm poses to pets, people and livestock, addresses concerns about the food supply and explains why reporting infestations is critical.

State officials and researchers warned Texas lawmakers in May that New World screwworm was advancing toward the state and could carry a billion-dollar economic toll.

The head of the Texas & Southwestern Cattle Raisers Association says ranchers should report suspected screwworm cases quickly and not panic as Texas responds to the outbreak.
