Pork futures hold steady amid strong retail demand - CME

Sep 01, 2025

Chicago Mercantile Exchange (CME) cattle futures fell on Monday as renewed concerns over the spread of New World screwworm pulled cattle futures off contract highs set during the previous week, reported Reuters.

The US Department of Health and Human Services (HHS) on Sunday reported the first human case in the United States of travel-associated New World screwworm, a flesh-eating parasite, from an outbreak-affected country.

The case, investigated by the Maryland Department of Health and the US Centers for Disease Control and Prevention, was confirmed by the CDC as New World screwworm on August 4, and involved a patient who returned from travel to El Salvador, HHS spokesman Andrew G. Nixon said in an email to Reuters.

The news prompted a wave of profit-taking, analysts said.

CME October live cattle futures fell 1.05 cents to settle at 236.825 cents per pound. September feeder cattle fell 0.775 cent to settle at 361.9 cents per pound.

A historically low supply of cattle, which has been further constrained by the closure of the US-Mexico border to feeder cattle imports due to the spread of screwworm, fuelled a rally in cattle futures the previous week.

Video: Five Confirmed New World Screwworm Cases Raise Alarm for Livestock and Pet Owners

Pat Hoffmann, Swine Technical Consultant at Elanco Animal Health tells us about the impact of New World Screwworm. The emergence of New World screwworm in the U.S. creates a threat for veterinarians, livestock producers and pet owners that has not been seen north of the Florida Keys since the fly was eradicated from the United States more than 50 years ago. New World screwworm (Cochliomyia hominivorax) larvae feed on living tissue and can affect a wide range of warm-blooded animals, including livestock, companion animals, wildlife, and even humans.
“New World screwworm could have a devastating impact on animal health, welfare, and producer livelihoods,” said Jeff Simmons, President and CEO, Elanco Animal Health. “We want to thank the FDA, EPA and USDA, for all their work to prepare for this threat. We’re committed to supporting our customers during this challenging time by delivering innovation, scientific expertise, and available resources to help treat New World screwworm and support the health and well-being of animals.”
Elanco is working alongside the U.S. animal health industry to help them fight against this parasite, offering a portfolio of options for pets and livestock that can help treat New World screwworm larvae infestations.
