The U.S. Department of Agriculture (USDA) has confirmed a second case of New World screwworm in Texas, specifically in a one-month-old calf located in Zavala County, about 5.6 miles from the first case reported earlier this month. This parasite poses a significant threat to livestock, wildlife, and even pets, as its larvae feed on living tissue, potentially leading to fatal wounds if untreated.

In response to this situation, the Canadian Food Inspection Agency has announced temporary restrictions on livestock imports from the affected areas in the U.S., which includes prohibiting animals that have been in Texas within the last 21 days from entering Canada.

USDA officials have reassured that the U.S. food supply remains safe, as the screwworm does not infest food products, and any affected animals would be identified during inspections. The USDA is actively working to control the pest's population through the release of sterile insects in the area.

Texas Farm Bureau President Russell Boening emphasized the importance of vigilance among livestock owners to ensure quick identification and eradication of any infestations
