一种可危害牛只的食肉寄生虫在得克萨斯州西部一头驼鹿身上被发现，促使官员呼吁猎人和牧场主协助阻止其扩散。
A flesh-eating parasite that can harm cattle was found in an elk in western Texas, prompting officials to ask hunters and ranchers to help stop its spread.
美国农业部周三表示，在佩科斯县一处狩猎牧场的一头驼鹿身上发现了新世界螺旋蝇。一名猎人在猎杀该动物后进行了举报。
The U.S. Department of Agriculture said Wednesday that New World screwworm was found in an elk on a game ranch in Pecos County. A hunter reported the animal after killing it.
美国农业部和得克萨斯州公园与野生动物部（TPWD）正在开展额外的野生动物监测，而得克萨斯州动物卫生委员会计划修改现有的疫区范围。
The USDA and the Texas Parks and Wildlife Department (TPWD) are conducting additional wildlife surveillance, while the Texas Animal Health Commission plans to modify an existing infested zone.
美国农业部在一份声明中说：“猎人和其他在疫区附近户外活动的人往往是最早接触到受感染野生动物的人群之一，这使得他们的观察对监测和应对工作尤为宝贵。”
"Hunters and others who spend time outdoors near infested areas are often among the first people to encounter affected wildlife, making their observations especially valuable to surveillance and response efforts," the USDA said in a statement.
声明续称：“随着得克萨斯州和其他州的狩猎季持续进行，鼓励猎人在观察、捕获或处理野生动物时保持警惕，留意新世界螺旋蝇的迹象。”
"As hunting seasons continue across Texas and other states, hunters are encouraged to stay alert for signs of NWS when observing, harvesting, or processing wildlife," it continued.
该机构敦促猎人留意伤口或体腔中是否有可见蛆虫、伤口是否开放或扩大、伤口是否有恶臭，以及动物是否显得虚弱或痛苦，并及时报告任何可疑情况。该机构补充说，鼻、口、耳、眼或生殖器周围的感染迹象也值得关注。
It urged hunters to be on the lookout for visible maggots in wounds or body openings, open or enlarging wounds, foul-smelling injuries, and animals that appear weak or distressed, and to report anything suspicious promptly. Infection signs around the nose, mouth, ears, eyes or genital areas also warrant attention, the agency added.
得州公园与野生动物部敦促猎人在解体或移动猎获动物前进行检查，同时留意动物是否表现出烦躁或消沉行为、食欲减退、甩头、有腐肉气味或异常孤立。
The TPWD urged hunters to inspect harvested animals before field dressing or moving them, and to also look out for irritated or depressed behavior, loss of appetite, head shaking, a smell of decaying flesh or unusual isolation in animals.
据福克斯新闻网此前报道，新世界螺旋蝇几十年前已在美国被消灭，但该寄生虫一直在通过中美洲和墨西哥向北移动。去年，美国暂停从墨西哥进口牲畜以防止其入境。暂停持续了一年多，给牛肉供应带来压力，并导致牛肉价格创下历史新高。分阶段恢复进口于8月开始。
New World screwworm was eliminated from the U.S. decades ago, but the parasite has been moving north through Central America and Mexico, Fox News Digital previously reported. Last year, the U.S. halted livestock imports from Mexico to keep it out. The pause lasted more than a year, straining cattle supply and contributing to record-high beef prices. Reopening began in stages in August.
6月，官员确认在得克萨斯州一头小牛身上发现了这种寄生虫。随后他们又在其他动物身上发现了它，包括一匹马和一只狗。
In June, officials confirmed the parasite in a Texas calf. They later found it in other animals, including a horse and a dog.
这头得克萨斯州的马鹿是当前疫情中美国首例确诊的野生动物病例。“得州公园与野生动物部生物学家与当地猎人和土地所有者之间的合作，加快了对这一新发现的确认和鉴定，”得州野生动物部门主管艾伦·凯恩在一份声明中说。
The Texas elk was the first confirmed U.S. wildlife case in the current outbreak. "The partnership between TPWD biologists and local hunters and landowners expedited the identification and confirmation of this new detection," Texas wildlife division director Alan Cain said in a statement.
新墨西哥州当局本周也报告了一头肉牛感染螺旋蝇，并划定了以该动物为中心的疫区。该疫区内的动物在转移前必须接受检查，并在必要时进行治疗。
New Mexico authorities also reported screwworm in a beef cow this week and established an infested zone around the animal. Animals within that zone must be inspected and, if necessary, treated before being moved.
据报道，这种寄生虫对动物健康和肉类生产构成威胁，但美国农业部表示它不影响食品安全。
The parasite is a threat to animal health and meat production, but the USDA says it does not affect food safety, according to reports.
全国牛仔牛肉协会在6月的一份声明中也表示，正与其州级合作伙伴共同抗击螺旋蝇，并赞扬了联邦根除工作，包括扩大苍蝇监测、牛只治疗和释放不育苍蝇。福克斯新闻数字频道已联系该协会寻求最新情况。
In a June statement, the National Cattlemen's Beef Association also said it was working with its state partners to combat screwworm, and praised federal eradication efforts including expanded fly surveillance, cattle treatments and sterile-fly releases. Fox News Digital has reached out to the group for an update.
