New cases of New World Screwworm have been confirmed in the United States, mainly in border states, raising concerns among livestock producers and regulators. The detections include multiple locations in New Mexico and Texas, showing a gradual spread within limited areas.
According to experts, one of the new cases was identified just a few miles from an earlier detection and involved a young calf. Additional cases were found in LaSalle County and Lea County in New Mexico, along with Gillespie County in Texas. These findings highlight the need for continued observation and rapid response.
The developments have drawn attention from Canada, a major agricultural trade partner. In response, Canadian authorities have placed temporary restrictions on livestock coming from affected regions of the United States. While the move is precautionary, experts believe the overall economic impact will likely remain small at this stage.
Despite these restrictions, there is some uncertainty about future actions from international partners. Authorities are closely monitoring the situation to prevent further spread and maintain trade flow.
Specialists note that controlling screwworm outbreaks is achievable. The sterile fly technique remains one of the most effective tools, helping reduce populations and stop reproduction. This method has been central to past eradication efforts.
At the farm level, strong biosecurity practices are essential. Farmers are encouraged to regularly inspect animals, quickly treat injuries, and work closely with veterinarians. Early detection can significantly reduce the risk of wider infection.
