Feral swine populations in the United States (US) are capable of carrying diseases that threaten the safety of the domestic swine industry. Performing routine, near-real time monitoring for an unusual rise in feral swine slaughter condemnation will increase situational awareness and early detection of potential animal health issues, trends, and emerging diseases. In preparation to add feral swine to APHIS weekly monitoring, a descriptive analysis of feral swine slaughter and condemnations was conducted to understand the extent of commercial feral swine slaughter in the US at federally inspected slaughter establishments and to determine which condemnation reasons should be included. There were 18 establishments that slaughtered 242,198 feral swine across seven states from 2017-2019. For all establishments combined, feral swine accounted for 63% of slaughtered animals. A total of 12 types of condemnation reasons were noted: Abscess/Pyemia, Arthritis, Contamination, Deads, Emaciation, Gen. Miscellaneous, Icterus, Injuries, Metritis, Misc. Degen. & Dropsic Condition, Misc. Parasitic Conditions, Moribund, Nephritis/Pyelitis, Non-ambulatory, Pericarditis, Pneumonia, Residue, Sarcoma, Septicemia, Sexual Odor, Toxemia, and Uremia. Exploratory analysis was conducted to determine which condemnation reasons should be included for weekly monitoring. For most condemn reasons, weeks of unusually high condemnations were noted. For example, a period of high pneumonia condemnations occurred from December 2, 2018 through February 3, 2019 with a spike on January 6, 2019 and a spike in dead swine occurred on November 3, 2019. The environmental impacts of more limited quality food resources, seasonal variation in the pathogen(s) causing pneumonia, and harsher weather are suspected to have an impact on the higher condemnation rates of pneumonia and dead swine during the winter months. Based on condemnation frequencies and the likelihood of each enabling situational awareness and early detection of feral swine health emerging diseases, the following were selected for weekly monitoring: abscess/pyemia, contamination/peritonitis, deads, emaciation, injuries, miscellaneous parasitic conditions, moribund, pneumonia and septicemia. Detection of notable increases in condemnation reasons strongly suggestive of foreign animal or emerging diseases should contribute valuable evidence towards the overall disease discovery process when the anomalies are both confirmed with follow up investigation and combined with other types of surveillance.

2017-2019 年美国联邦检查的屠宰企业的野猪商业屠宰和谴责

美国 (US) 的野猪种群能够携带威胁国内养猪业安全的疾病。对野猪屠宰谴责的异常上升进行常规、近乎实时的监测，将提高对潜在动物健康问题、趋势和新出现的疾病的态势感知和早期检测。在准备将野猪添加到 APHIS 每周监测中时，对野猪屠宰和报废进行了描述性分析，以了解美国联邦检查的屠宰企业的商业野猪屠宰程度，并确定应包括哪些报废原因。从 2017 年到 2019 年，共有 18 家企业在七个州屠宰了 242,198 头野猪。对于所有机构的总和，野猪占屠宰动物的63%。共记录了 12 种谴责原因：脓肿/脓肿、关节炎、污染、死亡、消瘦、杂项、黄疸、伤害、子宫炎、杂项。德根。& Dropsic 条件，杂项。寄生虫病、垂死的、肾炎/肾盂炎、不能走动的、心包炎、肺炎、残留物、肉瘤、败血症、性气味、毒血症和尿毒症。进行了探索性分析以确定每周监测应包括哪些谴责原因。出于大多数谴责的原因，数周以来都出现了异常高的谴责。例如，2018 年 12 月 2 日至 2019 年 2 月 3 日发生了一段高肺炎谴责期，2019 年 1 月 6 日出现高峰，2019 年 11 月 3 日出现死猪高峰。更有限的优质食品资源、引起肺炎的病原体的季节性变化以及更恶劣的天气对环境的影响被怀疑会影响冬季月份肺炎和死猪的较高报废率。根据谴责频率和每个使情况意识和早期发现野猪健康新出现疾病的可能性，选择以下进行每周监测：脓肿/脓肿、污染/腹膜炎、死猪、消瘦、受伤、各种寄生虫病、垂死的、肺炎和败血症。
