A flesh-eating parasite, the New World screwworm, has been detected in Texas livestock, prompting a surge in stock trading for Zoetis and Elanco Animal Health. Zoetis shares rose nearly 4%, with options volume increasing significantly as traders anticipated a rise in stock value. The FDA recently approved an injectable treatment for the pest, heightening market interest. Experts warn that if the parasite spreads, it could strain the beef supply chain, impacting consumer perceptions and market volatility. Cattle futures remain resilient amid a broader rally, but supply concerns loom if the situation escalates.
