Shoppers are keeping a close eye on what the return of the screwworm could mean for their grocery bills after federal officials confirmed new cases in Texas cattle this week.
The screwworm is a flesh-eating parasite that was long eradicated from U.S. livestock and has reappeared in American cattle for the first time in decades.
The USDA says at least three infections of the parasite have been detected. While experts don't expect beef prices to rise immediately, they warn that a wider outbreak could eventually lead to steady price increases.
Beef costs are already at record highs due to shrinking cattle herds nationwide, leaving the industry with little room for additional strain.
