Screwworm Invasion Threatens US Livestock and Beef Prices

The New World screwworm, a flesh-burrowing parasite, is spreading near the U.S.-Mexico border, threatening livestock and driving up beef prices. - The screwworm has been detected within 100 miles of the U.S.

border, prompting a ban on live cattle imports from Mexico. - Beef prices are at record highs, with ground beef up 77% since January 2020, due to drought and supply disruptions.

- The USDA is building a $750 million facility to produce sterile flies to combat the pest, but officials expect infestation is inevitable. - Ranchers are advised to monitor animals and use medications judiciously to prevent resistance.

Officials warn that re-eradication will take time and require coordinated efforts across states and countries.
