You Bought Livestock at the Local Auction Barn. Now What?

Jan 19, 2026

By John Yost and Greg Habing et.al

Livestock auctions are a cornerstone of local agricultural commerce. They are not just a place to buy and sell livestock but also serve as a point of access to the larger national marketplace for the local producer. Collectively, livestock auctions provide legal security for financial transactions. They also become the point of price discovery to determine the real value of the livestock marketed.

However, much like travelers in an airport, bringing together animals from many different locations can result in the spread of bacteria, viruses, and parasites. Additionally, the process of trucking animals to the facility, comingling them with animals from other locations, and then transporting them to their next destination creates stress that increases their susceptibility to new pathogens. This fact sheet provides general recommendations on the initial management of newly acquired livestock purchased from a local livestock auction. Included are specific recommendations for the different species of livestock/poultry may be implemented after consultation with your veterinarian.

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.
