NMPF Statement on the Return of New World Screwworm

From NMPF President & CEO Gregg Doud:

The return of New World screwworm to the United States decades after its initial eradication is a disappointing milestone, but it’s also one for which dairy producers have been preparing for more than a year, in collaboration with USDA and across agriculture. It’s important to remember that this development has no effect on food safety, and that measures to combat both the screwworm and its spread are in place and time-tested. We appreciate the U.S. Department of Agriculture’s proactive efforts to prepare for this moment, and we stand ready to work with the department to address any ongoing challenges. 

Now that USDA has confirmed that screwworm is here, dairy farmers and all livestock producers pledge close collaboration with USDA, state and local officials, and producer organizations to mitigate any harmful effects and educate farmers on how to protect their herds. We have been creating resources to guide farmers in their responses, and we will keep our members well informed of any important screwworm developments.  

We also urge officials to follow scientific guidance in any decisions affecting animal movements and regulatory responses to avoid causing economic harm that could be greater than the screwworm itself. We also ask that adequate resources be provided to combat this problem, which causes suffering in animals and creates risk for producers. 

NMPF, FARM Focus on New World Screwworm Prevention

Three top USDA experts led a discussion of the latest updates, detection methods and more during a one-hour live webinar on Sept. 22 exploring New World screwworm hosted by NMPF and the National Dairy FARM Program.

With the screwworm now reported to be 70 miles south of a Mexican-U.S. border state, efforts to protect cattle and prevent spread are ratcheting up. NMPF and FARM are monitoring the situation closely, creating a fact sheet for producers, available here. USDA is taking an “all hands on deck” approach to manage the malady, said Dr. Christopher Needham, deputy director of USDA’s Animal and Plant Health Inspection Services (APHIS).

“We actually have boots on the ground now looking at this, doing a full investigation, as well as considering what our next steps are to protect the border at all costs,” Needham said. “The entire federal government is looking at this as a national priority, and a national approach is needed to really make sure that we’re protecting agriculture here in the United States.”

Needham spoke to more than 80 attendees of USDA’s key strategy to work across agencies to ensure an effective response. Dr. Needham provided an overview of the screwworm outbreak followed by USDA’s five-pronged plan, with ongoing efforts to increase the Sterile Insect Technique, import requirements, surveillance and trapping of screwworm.

Dr. Rosemary Sifford, deputy administrator for USDA’s APHIS, also joined the call to discuss the agency’s efforts to update the NWS Strategy Plan. USDA is currently drafting the NWS Incident Playbook, a resource that provides quick, practical access to tools and methods used to respond to NWS.

Participants also learned the proper steps for reporting suspected cases to safeguard animal health and protect livestock. Producers are encouraged to report any suspicion of NWS to their veterinarian, state vet, USDA office or extension agent.

Chief Veterinary Officer for the Food and Drug Administration, Dr. Tristan Colonius, rounded out the webinar with information on animal drugs for New World screwworm. There are currently no approved products for treating or preventing NWS. FDA is reviewing potential drugs as part of the coordinated response.

Recent reports have detected New World screwworm in cattle just 70 miles from the northern border state of Nuevo Leon. This is the closest case to the U.S. border since the outbreak began last year.

Producers should continue to enforce biosecurity measures on farms to bolster efforts in mitigating the spread.
