US suspends livestock exports to Mexico over New World screwworm detection

The United States has imposed an immediate ban on the export of cattle and other animals to Mexico due to the confirmed presence of the New World screwworm in the U.S. The Animal and Plant Health Inspection Service (APHIS) announced the suspension, which affects livestock for slaughter and breeding, wild ruminants, equines, sheep, goats, companion dogs, breeding pigs, ferrets, and various types of birds.

The parasite, which lays eggs in the wounds of warm-blooded animals, can cause significant harm and death. The U.S. Department of Agriculture (USDA) has confirmed five cases of the screwworm, initially detected in Texas and now also identified in New Mexico. This marks a concerning spread of the pest.

Two new cases were reported in Texas, one in La Salle County and another in a goat in Gillespie County. A third new case, initially thought to be in Texas, was identified in a dog in New Mexico. The USDA has launched an epidemiological investigation into these new infections. Authorities suspect the dog in New Mexico may have recently traveled from Mexico before entering the United States, raising concerns about cross-border transmission.

In response to the outbreak, the U.S. is also maintaining its suspension on the import of livestock from Mexico. This reciprocal measure aims to prevent further spread of the parasite. The situation underscores the ongoing challenges in managing transboundary animal health issues and the need for robust surveillance and control measures.
