What happened

After the first confirmation of the flesh-eating parasite screwworm on a US farm in decades, federal and state officials have fanned out in South Texas, where a calf was found infested this week.

Why it matters

US agriculture secretary Brooke Rollins said on Thursday no other infestations of cattle or other animals have been detected around the confirmed case.

Common ground

The case in La Pryor, Texas, is a blow to US cattle ranchers who have been bracing for a domestic outbreak of New World screwworm as the fly advanced north through Mexico over the past year.

Perspective signals

The tension in the story is sharpened by Loaded Language, Appeal to Fear: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
