The National Cattlemen’s Beef Association (NCBA) announced support for the U.S. Department of Agriculture’s (USDA) decision to close the U.S. southern border to shipments of cattle, bison, and horses, due to the continued spread of New World screwworm beyond the phytosanitary border put in place to stop its advance. Today’s announcement is the latest move to halt the spread of this invasive pest that puts the entire U.S. livestock industry at risk.
“For months, NCBA and affiliated state cattle industry associations have been working with USDA officials urging their counterparts in Central America to take stronger action to stop the spread of New World screwworm. In the 1960s, America’s cattle and livestock producers spent years and millions of dollars to eradicate New World screwworm from the United States,” said NCBA CEO Colin Woodall.
The United States has long maintained its commitment to fighting New World screwworm by funding the production of sterile flies needed to keep this pest out of Central and North America. Despite the United States’ work to control the pest, weak governmental participation in Central America allowed the insect to spread north out of Panama. This has been coupled with a lack of timely action by officials in Mexico and now the U.S. cattle herd, other livestock, wildlife, pets, and humans are all at risk again.
NCBA has been working closely with USDA to monitor the situation and has also appealed directly to the Mexican government to do more to intervene and stop the spread. However, a variety of factors have allowed the northward migration of the pest to continue. NCBA and state affiliate volunteer leaders and staff have also worked with members of Congress to help support USDA’s efforts and will continue to seek every possible avenue to protect the U.S. cattle industry by preventing New World screwworm from reentering the United States.
