The Return of the New World Screwworm to the United States and State Regulations
新世界螺旋蛆重新入侵美國及各州監管規定
Introduction
The United States Department of Agriculture (USDA) has confirmed that the New World Screwworm has returned to Texas, leading several southern states to introduce strict rules on moving animals.
美國農業部（USDA）已確認新世界螺旋蛆重新出現在德州，導致多個南方州針對動物運輸採取嚴格規定。
Main Body
The current threat comes from the New World Screwworm, a parasitic insect whose larvae eat the living tissue of warm-blooded animals. Although this species was removed from the U.S. in 1966, recent movements from Central America and detections in Mexico in late 2024 have allowed it to return. In Texas, there are four confirmed cases, including a calf and a dog in La Salle and Andrews counties.
目前的威脅來自新世界螺旋蛆，這是一種寄生昆蟲，其幼蟲會啃食溫血動物的活體組織。雖然該物種在1966年已從美國清除，但近期從中美洲遷入以及2024年底在墨西哥的檢測，使其得以回歸。在德州，已有四起確診個案，包括 La Salle 和 Andrews 縣的一頭小牛和一隻狗。
In response, several states have introduced strict security measures. Governor Greg Abbott declared a disaster for all Texas counties, emphasizing that the parasite is a serious threat to the livestock industry and the economy. Consequently, Texas now forbids moving warm-blooded animals in or out of affected zones without a veterinary permit. Similarly, Louisiana requires an Official Certificate of Veterinary Inspection for animals passing through these zones. Florida has also created emergency rules to limit animal imports from high-risk areas, which Commissioner Wilton Simpson described as a necessary step to protect the state's animals.
對此，多個州已採取嚴格的安全措施。州長 Greg Abbott 宣布德州所有縣進入災難狀態，強調該寄生物對畜牧業和經濟構成嚴重威脅。因此，德州目前禁止在沒有獸醫證明的情況下，將溫血動物移入或移出受影響區域。同樣地，路易斯安那州要求動物通過這些區域時必須持有正式的獸醫檢驗證明書。佛羅里達州也制定了緊急規定，限制從高風險地區進口動物，委員 Wilton Simpson 稱這是保護該州動物的必要步驟。
Other states have focused on increased monitoring. Arkansas and New Mexico have urged farmers and travelers to watch for and report unusual wounds. Meanwhile, the USDA is using a strategy that involves releasing sterile male flies to stop the parasite from reproducing. To support this effort, the USDA plans to increase the production of sterile flies and build a new manufacturing plant in Texas.
其他州則專注於加強監控。阿肯色州和新墨西哥州敦促農民及旅客留意並通報異常傷口。同時，美國農業部正採取一項策略，透過釋放不育的雄性蒼蠅來阻止寄生物繁殖。為了支持這項工作，美國農業部計劃增加不育蒼蠅的產量，並在德州建設一座新的生產廠。
Conclusion
The USDA and various state governments are currently using a combination of travel restrictions and biological controls to stop the spread of the New World Screwworm.
美國農業部與各州政府目前正結合旅遊限制與生物控制手段，以阻止新世界螺旋蛆的傳播。
Vocabulary Learning
💡 The 'Power-Up': Moving from Simple to Precise
At the A2 level, you describe things using general words. To hit B2, you need precision. Look at how this text describes a problem and the solution. Instead of saying "The bug is bad," it uses "serious threat."
🚀 Precision Shift: The 'Action' Vocabulary
Stop using "do" or "make" for everything. Observe these B2-level verbs from the text and how they change the meaning:
- Introduce (Not just 'start') To officially bring in a new rule or law.
- Emphasize (Not just 'say') To show that something is very important.
- Urge (Not just 'ask') To strongly encourage someone to act immediately.
- Limit (Not just 'stop') To keep something within a specific boundary.
🛠️ The "Connector" Strategy
A2 students write short, choppy sentences. B2 students link ideas to show cause and effect.
The Secret Ingredient: "Consequently" In the article, we see: "...serious threat to the livestock industry and the economy. Consequently, Texas now forbids..."
Instead of saying "and so," use Consequently to sound more professional and academic. It signals to the reader that the second action is a direct result of the first.
