USDA in Mexico looking for answers on movement of NWS infected cow

USDA staff in Mexico are investigating how a cow infected with New World Screwworm was transported from southern Mexico to a location only 70 miles from the US border.

That is Deputy Under Secretary for Marketing and Regulatory Programs Lauren Stump, just days after USDA announced an infected 8-month-old cow was moved to a feedlot in Northern Mexico.

Ag Secretary Brooke Rollins accused Mexico of not doing enough to combat New World Screwworm’s spread and vowed to step up U.S. efforts to protect the U.S. beef industry and consumers.

USDA says it is also planning to add more cattle fever tick patrol officers and detector dogs. USDA launched a multi-million-dollar action plan last month which includes new sterile fly production facilities.
