A dangerous worm is back in Texas and New Mexico. The government is working fast to help farm animals.

一種危險的寄生蟲在德克薩斯州與新墨西哥州再次出現。政府正迅速採取行動救援農場動物。

Experts found the worm in five animals. They found it in cows, a goat, and a dog. The worm comes from South America. It likes warm and wet weather.

專家在五隻動物身上發現了這種寄生蟲。他們在牛、一隻山羊和一隻狗身上發現了它。這種寄生蟲來自南美洲，偏好溫暖且潮濕的天氣。

Governor Greg Abbott says this is an emergency. Many offices are working together. The worm eats the skin of living animals. This can kill the animals.

州長 Greg Abbott 表示目前處於緊急狀態。許多部門正共同協作。這種寄生蟲會啃食活體動物的皮膚，可能導致動物死亡。

Mexico closed its border to US cows. This is bad for the beef business. Meat prices might change. Canada also stopped some animals from Texas because they are afraid of the worm.

墨西哥已禁止美國牛隻入境。這對牛肉產業不利，肉價可能會因此變動。加拿大也因擔心這種寄生蟲，停止了部分德克薩斯州動物的進口。

The government is still looking for the worms. They want to kill all the worms and save the farms.

政府仍在搜尋這些寄生蟲。他們希望消滅所有寄生蟲並拯救農場。

The United States has reported the return of the New World screwworm parasite in Texas and New Mexico. This has led to emergency responses from state and federal authorities to protect livestock and reduce economic risks.

美國報告指出德克薩斯州與新墨西哥州重新出現了新世界螺旋蛆寄生蟲。這導致州政府與聯邦當局採取緊急應對措施，以保護牲畜並降低經濟風險。

The USDA has confirmed five cases of the parasite in calves, a goat, and a dog. This problem is part of a larger trend where the parasite has been moving north from South America and the Caribbean through Mexico. Experts emphasize that humid climates help the parasite spread, and they warn that rising global temperatures may make Gulf Coast states more vulnerable by 2055.

美國農業部（USDA）證實了五起寄生蟲病例，涉及小牛、一隻山羊與一隻狗。這個問題是一個較大趨勢的一部分，即寄生蟲正從南美洲與加勒比海經墨西哥向北移動。專家強調潮濕的氣候有助於寄生蟲傳播，並警告全球氣溫上升可能會使墨西哥灣沿岸各州在2055年前變得更加脆弱。

In response, Governor Greg Abbott activated the State Emergency Operations Center to coordinate animal health and public health officials. Some Texas counties have declared disasters, and officials have asked for a national emergency declaration to get more resources. This urgency is necessary because the parasite's larvae eat living tissue, which can kill animals if they are not treated quickly.

作為回應，州長 Greg Abbott 啟動了州緊急行動中心，以協調動物健康與公共衛生官員。德州部分郡已宣布為災難區，官員已要求宣布國家緊急狀態以獲取更多資源。由於這種寄生蟲的幼蟲會取食活組織，若不迅速治療可能會導致動物死亡，因此這種緊迫性是必要的。

These events have caused serious economic problems. The US beef industry has dropped to its lowest level in 75 years because the US-Mexico border is closed to live cattle imports. Furthermore, there are concerns about the USDA's ability to handle the crisis due to a loss of experienced animal health specialists. Internationally, Canada has temporarily banned livestock imports from Texas to prevent the parasite from entering its own territory.

這些事件造成了嚴重的經濟問題。由於美墨邊境關閉活牛進口，美國牛肉業已跌至75年來的最低水平。此外，由於缺乏經驗豐富的動物健康專家，外界對 USDA 處理危機的能力表示擔憂。在國際方面，加拿大已暫時禁止從德州進口牲畜，以防止寄生蟲進入其領土。

The situation is still developing as the USDA and state agencies continue to monitor the area and work to remove the parasite to stabilize the agricultural economy.

由於 USDA 與州政府部門繼續監控該地區並努力清除寄生蟲以穩定農業經濟，情況目前仍在發展中。

The United States has recorded the reemergence of the New World screwworm parasite in Texas and New Mexico, prompting state and federal emergency responses to mitigate livestock and economic risks.

美國記錄到新世界螺旋蠅寄生蟲在德克薩斯州與新墨西哥州重新出現，促使州與聯邦政府採取緊急應對措施，以降低畜牧業與經濟風險。

The current crisis is characterized by the detection of five confirmed cases of the New World screwworm, distributed across Texas and New Mexico. The USDA identified infestations in calves, a goat, and a dog. This biological incursion follows a multi-year northward migration of the parasite from South America and the Caribbean through Central America and Mexico. The susceptibility of the region is exacerbated by the parasite's preference for humid climates, with projections suggesting that rising global temperatures may increase the vulnerability of Gulf Coast states by 2055.

目前的危機特徵是在德克薩斯州與新墨西哥州偵測到五起確診的新世界螺旋蠅個案。美國農業部（USDA）在小牛、一隻山羊與一隻狗身上發現感染。此次生物入侵是由於該寄生蟲從南美洲與加勒比海，經過中美洲與墨西哥，歷時多年向北遷移所致。該地區因該寄生蟲偏好潮濕氣候而更易受影響，預測顯示全球氣溫上升可能會在2055年前增加墨西哥灣沿岸各州的脆弱性。

In response to these detections, Governor Greg Abbott activated the State Emergency Operations Center at Level II, centralizing a multi-agency effort involving animal health, agriculture, and public health officials. Concurrently, several Texas counties have declared local states of disaster, while some officials have petitioned for a national emergency declaration to secure additional resources. The administration's strategy emphasizes rapid detection and the deployment of all available state assets to prevent a systemic collapse of the livestock sector. This urgency is underscored by the parasite's biological mechanism: larvae consume living tissue, which can result in animal mortality if untreated.

針對這些偵測結果，州長 Greg Abbott 將州緊急行動中心啟動至第二級，集中由動物健康、農業與公共衛生官員組成的多機構協作。與此同時，德克薩斯州多個郡已宣布進入當地災難狀態，而部分官員已請願將其定為國家緊急狀態以獲取額外資源。政府的策略強調快速偵測並部署所有可用州資源，以防止畜牧業系統性崩潰。由於該寄生蟲的生物機制——幼蟲會食用活體組織，若不治療將導致動物死亡，這使得情況更為緊迫。

Institutional and economic implications are significant. The US beef industry has experienced a contraction to a 75-year low following the closure of the US-Mexico border to live cattle imports. Furthermore, the potential for supply chain disruptions in the top cattle-producing state could induce price volatility in protein products, a risk potentially compounded by external geopolitical instabilities affecting energy costs in the Strait of Hormuz. Internally, concerns have been raised regarding the USDA's operational capacity following a reported exodus of animal health specialists during previous administrative shifts.

制度與經濟影響顯著。由於美墨邊境禁止活牛進口，美國牛肉業已縮減至75年來最低點。此外，最大牛產州潛在的供應鏈中斷可能會引起蛋白質產品的價格波動，而荷姆茲海峽影響能源成本的外部地緣政治不穩定可能會加劇此風險。在內部方面，由於此前行政更替期間據報有動物健康專家流失，相關人士對美國農業部的運作能力表示擔憂。

International biosecurity responses have been swift. The Canadian Food Inspection Agency (CFIA) implemented temporary prohibitions on the import of livestock from Texas, requiring a 21-day absence from the state prior to entry. While the Canadian Cattle Association suggests that the limited volume of trade between Canada and Texas minimizes immediate disruption, the measure reflects a broader commitment to preventing the parasite's entry into Canadian territory, where cold winters are expected to inhibit the fly's survival.

國際生物安全反應迅速。加拿大食品檢驗局（CFIA）對從德克薩斯州進口的畜牧產品實施臨時禁令，要求在進入前必須離開該州21天。雖然加拿大牛業協會認為加拿大與德克薩斯州之間的貿易量有限，短期影響較小，但此措施反映了防止該寄生蟲進入加拿大領土的更廣泛承諾，預計寒冷的冬天將抑制該蠅類的生存。

The situation remains fluid as the USDA and state agencies continue surveillance and containment efforts to eradicate the parasite and stabilize the agricultural economy.

由於美國農業部與州政府部門持續進行監測與圍堵工作，以根除該寄生蟲並穩定農業經濟，情況仍處於流動狀態。
