According to Reuters, on Oct. 7^th  a New World screwworm (NWS) infected calf, traced to a herd from southern Mexico, was intercepted in Montemorelos, about 60 miles south of Monterrey. Mexican officials reported that the larvae found were dead or dying due to mandatory antiparasitic treatments, including ivermectin. This marks Nuevo León’s second case in two weeks, although Mexico’s government said the incidents are unrelated. U.S. Agriculture Secretary Brooke Rollins confirmed that the latest case occurred roughly 100 miles farther north than the last and described it as “an isolated incident.”

•The Food and Drug Administration (FDA) has approved the use of Dectomax -CA1 (a doramectin injection) for the prevention and treatment of NWS infestations in cattle. The drug is approved to prevent and treat screwworm larval infestations and prevent reinfestation for 21 days.

•Texas A&M AgriLife and the Office of Radiological Security, ORS, part of the National Nuclear Security Administration, NNSA, is teaming up on a national effort to combat New World screwworm, NWS, including producing sterile flies in the U.S. via electron beam, or eBeam, technology to halt fly reproduction.
