New World Screwworm: What Is It & What Could It Do To The Cattle Industry Beware! New World Screwworm In Cattle New World Screwworm: What you Need to KnowOn November 22, 2024, the Chief Veterinary Officer of Mexico informed the United States Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) of a confirmed case of New World screwworm (NWS, Cochliomyia hominivorax). This alarming detection poses a serious threat to livestock and wildlife in North America. Here’s what you need to know about this devastating pest and its implications.
What Is New World Screwworm?New World screwworm is a highly destructive pest that affects livestock, other warm-blooded animals, and occasionally humans. NWS larvae infest animals through open wounds or mucous membranes, feeding on living tissue rather than dead tissue or carrion. If left untreated, infestations can be fatal.
Key Facts About New World Screwworm:- NWS is endemic to Cuba, Haiti, the Dominican Republic, and parts of South America.
- It has been moving northward since 2023, spreading from Panama to Costa Rica, Nicaragua, Honduras, Guatemala, and now Mexico.
To protect livestock and wildlife in the United States, APHIS is taking immediate action:
Import Restrictions:- Livestock imports, including equines, from Mexico are temporarily restricted.
- Horses originating from or residing in Mexico within 60 days prior to export will need to comply with stringent import protocols.
- Pre-export treatment and examination.
- Treatment and examination upon arrival.
- A 7-day quarantine in an approved permanent import facility.
These protocols follow the guidelines outlined in eCFR 9 CFR 93.308 and VSG 13424.1.
Why Awareness MattersIllegally imported equines and stray animals crossing the border could introduce NWS into the United States. It is crucial for those handling livestock and pets to be vigilant.
Signs of Screwworm Infestation:- Draining or enlarging wounds.
- Signs of discomfort such as head shaking or irritated behavior.
- Presence of screwworm larvae (maggots) or eggs.
Screwworm eggs are creamy-white and often found near the edges of wounds. Infestations commonly occur in:
- Navels of newborn animals.
- Nasal or eye openings.
- Genitalia and branding or dehorning wounds.
If you notice signs of infestation:
- Immediately contact your local accredited veterinarian, state animal health official, or APHIS veterinarian.
- Regularly inspect your pets and livestock, especially if they have wounds or show signs of discomfort.
The detection of New World screwworm in Mexico underscores the importance of vigilance in safeguarding livestock and wildlife. By adhering to import restrictions and monitoring animals closely, we can help prevent the spread of this devastating pest.
