USDA Implements Stricter Import Controls Amid Screwworm Threat to Pets
The New World screwworm, a flesh-eating parasite, poses a renewed threat to pets, wildlife, and potentially humans in the U.S. The parasite, which was eradicated from the U.S. decades ago, has been detected in a Texas calf, raising concerns about its reintroduction. Federal agencies, including the USDA, have tightened import controls to mitigate the risk, particularly for animals coming from affected regions. Dogs entering the U.S. from these areas must have health documents certifying they are free of the parasite or have been treated. Additional inspections are conducted at the border. The parasite can cause severe pain and infection in pets, with untreated infestations potentially leading to death. While the risk to pets within the U.S. remains low, vigilance is advised for animals that have traveled from high-risk areas.
