(NATIONAL) - A flesh-eating parasite is moving closer to the United States, raising concern for the livestock industry and federal agriculture officials.
The New World screwworm has been detected about 60 miles from the U.S.-Mexico border in northern Mexico, according to the Texas Department of Agriculture.
State Agriculture Commissioner Sid Miller says the discovery puts Texas at immediate risk if the parasite spreads north.
The screwworm is a fly whose larvae burrow into living tissue. According to the Centers for Disease Control and Prevention, the insects lay eggs in open wounds or body openings of warm-blooded animals. Once hatched, the larvae feed on flesh and can be fatal if untreated.
While the parasite primarily affects livestock, it can also impact pets and humans.
Federal officials say the screwworm is not currently present in the United States. However, efforts are underway to prevent its spread.
The United States Department of Agriculture has been releasing millions of sterile male flies along the southern border. The strategy is designed to reduce reproduction by ensuring females mate with sterile males, preventing eggs from hatching.
Officials say about 100 million sterile flies are currently released each week, with plans to increase that number significantly once a new production facility in Texas is completed.
The USDA is also using traps along the border to monitor for any sign of the parasite.
Agriculture officials warn early detection will be critical to preventing an outbreak that could impact cattle herds and the broader food supply.
