Market Day Report

MEXICO CITY (RFD-TV) — New World Screwworm remains isolated in Mexico, but it is closer to the U.S. southern border than ever before. The first new case was in a calf located less than 200 miles from the U.S. border, marking the parasite’s closest approach to America. The second case was reported the following day in a goat near Mexico City.

Rich Nelson, chief strategist with Allendale, Inc., told RFD-TV News that the markets are closely watching that action this week.

“We’re watching those two updates from last week where USDA did confirm this discussion about two new cases of screwworm in Mexico,” Nelson said. “One of those cases was within 200 miles of the border. So as far as it stands, starting out this week, a little premium is still being added from that screwworm concern -- and the confirmation that we will not be raising that or opening that Mexican border.”

Authorities report more than 13,000 cases of New World Screwworm in Mexico since late 2024.
