U.S. confirms second Texas screwworm case, Canada restricts livestock imports

## Livestock Health Alert: Second Texas Case of New World Screwworm Confirmed, Border Restrictions Implemented

**AUSTIN, TX –** U.S. animal health officials have confirmed a second case of New World screwworm in Texas, prompting swift action from Canadian authorities to restrict livestock imports. The parasitic insect, known for its larvae’s ability to infest and feed on the living tissue of warm-blooded animals, poses a significant threat to livestock health and agricultural economies.

The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) confirmed the latest case in a domestic animal in South Texas, following an initial detection in a wild-caught animal in the same region last month. The New World screwworm (Cochliomyia hominivorax) is a serious pest that, if left untreated, can cause severe wounds and potentially fatal infections in livestock, including cattle, sheep, goats, and even pets.

The larvae of the New World screwworm lay their eggs in the open wounds of warm-blooded animals. Upon hatching, the larvae burrow into the flesh and feed on the living tissue, causing extensive damage. This parasitic infestation can lead to secondary infections, significant debilitation, and in severe instances, death. The economic impact of a widespread outbreak can be devastating, affecting producers through increased veterinary costs, reduced animal productivity, and potential trade disruptions.

In response to the confirmed cases, Canada’s Food Inspection Agency (CFIA) has implemented immediate import restrictions on live cattle, sheep, and goats originating from Texas. The CFIA stated that these measures are a precautionary step to prevent the introduction of the New World screwworm into Canada’s livestock population. The agency is working closely with U.S. counterparts to monitor the situation and assess any potential risks to Canadian animal health.

U.S. officials are actively engaged in surveillance and eradication efforts in the affected areas of Texas. These efforts include investigating the source of the infestation, monitoring animal populations for signs of infection, and implementing control measures to prevent further spread. The goal is to contain and eliminate the New World screwworm before it can establish a permanent presence in the United States.

The presence of this parasite in Texas underscores the importance of robust animal health surveillance programs and international cooperation in managing transboundary animal diseases. Producers are being urged to remain vigilant, inspect their animals for any signs of wounds or parasitic infestation, and report any suspected cases to their local veterinary authorities immediately. Early detection and rapid response are critical in mitigating the impact of such threats.

The confirmation of a second case, while concerning, highlights the ongoing commitment of U.S. animal health agencies to transparency and proactive management of potential agricultural threats. The swift implementation of import restrictions by Canada demonstrates a coordinated approach to safeguarding continental livestock health. Continued vigilance and collaboration will be essential in navigating this evolving animal health challenge and protecting the vital agricultural sectors of both nations. The situation remains under close observation, with updates expected as surveillance and control efforts progress.
