Second Screwworm Case Confirmed in Texas: Implications for Cattle Ranchers

A second screwworm parasite case was confirmed in Texas, just miles from the first detection this week. This new case was found in Zavala County on a ranch. It involves a one-month-old calf, posing a challenge to cattle ranchers as these parasites can cause fatal damage to livestock.

The U.S. Department of Agriculture has confirmed a second case of the flesh-eating screwworm parasite in Texas. This latest occurrence, miles from the initial detection earlier this week, was identified in Zavala County on a ranch.

The USDA, confirming Reuters' earlier report, announced the infected animal is a one-month-old calf. According to Rear Admiral Michael Schmoyer, USDA's associate administrator for Animal and Plant Health Inspection Service, the infection currently involves only one animal.

This recent discovery follows the first case found in La Pryor, close to the U.S.-Mexico border. It represents a significant setback for American cattle ranchers, who face increasing threats from these parasites as they expand northward from Mexico. Screwworms, known to lay eggs in open wounds of warm-blooded animals, can cause severe damage if untreated.
