Iowa Department of Agriculture and Land Stewardship Issues Guidance to Protect Animals from New World Screwworm

Jun 11, 2026

The Iowa Department of Agriculture and Land Stewardship (IDALS) issued the following guidance for livestock producers, pet owners, and veterinarians to help protect animals from the parasitic New World Screwworm (NWS) fly. The guidance comes after multiple cases of NWS have been detected in livestock in Texas and one infestation was confirmed in a canine in New Mexico.

All livestock caretakers and pet owners should routinely inspect animals for open wounds. If maggots are detected in an open wound of a warm-blooded animal, report it to IDALS immediately at 515-281-5305 or Animal.Industry@iowaagriculture.gov.

When caught early, animals and wounds can be treated, and animals can fully recover from NWS.

Guidance for importing livestock and companion animals into Iowa from an infested zone:

Contact the State Animal Health Official in the state of origin for movement requirements.
Visit IDALS’ Animal Admission Health Requirements page or call 515-281-5547 to verify Iowa’s import requirements.

Video: Genetics vs Genomics in Swine - Dr. Max Rothschild

In this episode of The Swine it Podcast Show Canada, Dr. Max Rothschild, Distinguished Professor at Iowa State University, explains how genetics and genomics have transformed swine production. He explores genomic selection, key gene discoveries, and the role of gene editing in improving disease resistance and productivity. Practical insights on litter size, meat quality, and industry adoption are also discussed. Listen now on all major platforms!

"Genetic improvement in swine production accelerated significantly once molecular tools enabled identification of DNA level variation influencing growth, reproduction, and meat quality across commercial populations."

Meet the guest: Dr. Max Rothschild / max-f-rothschild-b3800312 earned his PhD in Animal Breeding from Cornell University and has spent over four decades at Iowa State University advancing swine genetics and genomics. His research focuses on genetic improvement, disease resistance, and molecular tools for swine production. A leader in pig genome research, his work has shaped modern breeding strategies.
