Flesh-eating screwworm infection confirmed in South Texas, USDA says
A case of New World screwworm has been confirmed in South Texas, the US Department of Agriculture announced Wednesday night. It marks the first detected breach of the US-Mexico border by the ravenous flesh-eating flies, which have been making their way up through Central America for the past several years.
In a social media post on Wednesday afternoon, the USDA revealed that a sample from Texas had been sent to the National Veterinary Services Laboratories (NVSL) in Ames, Iowa, for confirmatory testing of a screwworm infection. Agriculture Secretary Brooke Rollins later posted that the testing had confirmed the infection, which was found in a 3-week-old calf in Zavala County, Texas.
Chatter of a screwworm detection had already been building this week, rattling the US cattle industry.
