Experts say pest will not impact meat quality or consumer safety

The recent detection of the New World screwworm in the United States has caused volatility in the fed cattle futures market, but experts emphasize that it does not affect meat quality or supply. 

David Anderson, Ph.D., an agricultural economist with Texas A&M AgriLife Extension, explained that the pest can infest warm-blooded animals, including livestock and pets. However, he stressed that it is not a food safety issue. Animals can be successfully treated if infestations are identified early, and the meat remains safe for consumption. 

Following the announcement, cattle futures showed sharp fluctuations. Prices dropped from around $250 per hundredweight to $229 within a week. “Prices are going to stay high,” said Anderson. “But typically, retail prices for beef tend to level off and decline after the middle of the year, after we get past the grilling season rush. I don’t think this should have any effect on retail prices.” 

Fundamentally, the beef industry remains stable. The U.S. cow herd is at its smallest since 1961, beef production is lower than last year, and consumer demand continues to be strong. These factors are expected to keep beef prices elevated, particularly during the summer grilling season, although prices may ease later in the year. 

Producers are advised to focus on proper herd management. Preventative measures include treating wounds, monitoring animals for signs of infestation, and consulting veterinarians when needed. Reporting cases to the U.S. Department of Agriculture is also essential so sterile flies can be deployed to control the pest. 

Livestock producers are encouraged to monitor all animals, including horses and pets, as all warm-blooded species are vulnerable. Experts stress that while the screwworm is a serious pest, it has been managed successfully in the past, and existing strategies remain effective.

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.
