Texas Ag Commissioner Warns of Screwworm Threat Detected Near Border

Texas Agriculture Commissioner Sid Miller is warning ranchers and livestock producers to stay alert after a confirmed case of New World screwworm was detected in northern Mexico, just 90 miles from the US border.

Screwworm Detection Raises Immediate Concerns Near Texas Border

The recent detection in Nuevo León marks the closest confirmed case to Texas in years, raising concern about the potential spread into the state. The parasitic pest poses a serious threat to livestock, wildlife, and the broader food supply if not quickly contained.

Producers Urged to Act Quickly and Watch for Signs

Commissioner Miller is urging Texas producers to closely monitor their animals and report any unusual symptoms immediately. Screwworm infestations can spread rapidly, and early detection is critical to preventing widespread damage.

Agriculture officials emphasize there is little room for delay, warning that even a single undetected case could lead to significant economic losses for ranchers and the livestock industry.

State Prepared to Escalate Response Efforts

While the US Department of Agriculture has taken steps to respond, Miller noted that containment efforts have not fully stopped the pest’s spread. State and federal agencies are continuing to coordinate response strategies, with Texas prepared to take additional action if necessary.
