US Dairy Industry Prepares for Potential Screwworm Threat Resurgence

US dairy producers have been alerted to the potential re-emergence of the New World screwworm, a parasite eradicated from the United States years ago. This warning is due to the increased global movement of livestock, which heightens the risk of reintroduction. Experts stress the importance of education and biosecurity as primary defenses.

The screwworm's larvae feed on living tissue, creating severe wounds that can lead to infection, major production losses, and even death if not addressed promptly. Dairy veterinarians and extension specialists underscore early detection as critical to preventing severe animal welfare and financial issues.

Producers, farm workers, and veterinarians are encouraged to recognize infestation signs quickly, adhere to reporting protocols, and maintain ties with animal health authorities. Education programs play a crucial role in these preparedness efforts, according to DairyHerd.

Biosecurity measures, such as monitoring animal movements, careful wound management, and timely veterinary intervention, are essential. These practices are increasingly important given the potential impact of climate change and international trade on the reintroduction of pests.

Coordination between producers, veterinarians, universities, and government agencies will be vital if the threat materializes, highlighting the importance of proactive planning to mitigate potential outbreaks and safeguard the US dairy industry.
