(NewsNation) — 美国农业部表示，新世界螺旋蝇（NWS）首次在美国野生动物中传播的病例已在德克萨斯州被发现。
(NewsNation) — The first spread of the New World screwworm (NWS) in U.S. wildlife has been detected in Texas, according to the U.S. Department of Agriculture (USDA).
美国农业部动植物卫生检验局周二称，在一头麋鹿身上发现了这种螺旋蝇。据该联邦机构称，这头麋鹿是在一个狩猎场被猎人捕获后报告的。
The USDA's Animal and Plant Health Inspection Service said Tuesday the screwworm was found in an elk. According to the federal agency, the elk was reported after it was harvested by a hunter on a game ranch.
美国农业部在一份新闻稿中表示：‘这一发现凸显了猎人、土地所有者、户外爱好者和野生动物专业人士在帮助发现和阻止NWS传播方面所起的关键作用。’
"This detection highlights the critical role hunters, landowners, outdoor enthusiasts, and wildlife professionals play in helping detect and stop the spread of NWS," the USDA said in a news release.
联邦和州政府官员表示，他们正在扩大该地区的监测范围，并敦促猎人、土地所有者和户外爱好者注意感染迹象，并迅速报告可疑病例，以帮助防止进一步传播。’
Federal and state officials said they are expanding surveillance in the area and urging hunters, landowners and outdoor enthusiasts to watch for signs of infestation and report suspicious cases quickly to help prevent further spread.
美国农业部的这一声明是在美国食品药品监督管理局（FDA）6月份扩大针对这种寄生虫的动物治疗选项之后发布的。
The USDA's announcement follows the FDA's June expansion of treatment options for animals aimed at fighting the flesh-eating parasite that poses a growing threat to livestock.
同一个月，美国农业部在墨西哥建立了一个占地22,000平方英尺的无菌苍蝇生产设施，该设施能够生产多达1亿只苍蝇来对抗这种寄生虫，这种寄生虫已导致26起报告病例。
That same month, the USDA launched a 22,000-square-foot sterile fly production facility in Mexico that can produce up to 100 million flies to fight the parasite, which had been linked to 26 reported cases.
新世界螺旋蝇是一种寄生蝇，可以通过开放性伤口进入动物体内并以活组织为食。
