Cattle Market Guys - Tuesday Check In 6-30-2026

The U.S. and Mexico just opened a $50 million sterile fly facility in Chiapas capable of producing 100 million flies per week — and it may be the most important biosecurity development for cattle producers in years. New World screwworm cases are creeping north, and this is the primary weapon to push the eradication line back. Jim shares firsthand history from the original eradication effort that puts the stakes in sharp relief. In this Tuesday Market Update for June 30, 2026, Brock and Jim break down the latest feeder cattle price data, with 600-649 pound steers sitting at $413.01/cwt and lighter weights continuing to outperform at $454.45/cwt — but near-term forecasts point to softening ahead. The basis gap between cash and front-month futures at $368.94 is a signal producers shouldn't ignore. The episode also covers a coalition of 65 groups petitioning the FDA to end routine antibiotic use in livestock, a promising new BRD diagnostic tool out of Texas A&M, and heat stress production losses hitting European farmers. On the trade front, Australia has already filled its annual Chinese beef quota before mid-year, Senator Bill Cassidy has introduced tariff-rate quota legislation aimed at protecting domestic producers, and U.S. beef exports to Mexico show a soft April but a constructive year-to-date picture overall.
