The Minnesota Board of Animal Health is warning residents to stay alert for the New World Screwworm, a dangerous fly that can harm livestock, pets, wildlife, and even humans. While the risk of the pest becoming established in Minnesota is lower than in southern states, animal movement from affected regions could introduce it there. Outbreaks are currently active in Central America with detections in Mexico. State Veterinarian Dr. Brian Hoefs says Minnesota’s warm seasons are enough for the parasite to survive and spread. Livestock and pet owners are urged to watch for signs like maggot-filled wounds, foul odors, and unusual animal behavior. Anyone traveling with animals should follow import rules and monitor pets closely after returning home.
