-contaminated lymph nodes (LN), when included into edible meat products, are a potential source of foodborne disease. In this survey, ventral superficial cervical and mandibular LN were tested for the presence of from two sow processing plants in the midwestern United States. Results indicate that both LN can be contaminated with ; mandibular LN have higher prevalence ( < 0.05) of than cervical LN (16% vs. 0.91%), and the majority (>90%) of isolates are pan-susceptible or resistant to one antimicrobial, while 9.78% of isolates were multi-drug-resistant (MDR-resistant to three or more classes of antimicrobials). Intervention methods to prevent foodborne disease could include elimination of these LN from pork products or inclusion of LN only into products that are destined for cooking. Integrated multi-faceted intervention methods need to be developed to reduce in the food chain.
受污染的淋巴结（LN）若被纳入可食用肉类产品中，是食源性疾病的一个潜在来源。在本次调查中，对美国中西部两家母猪加工厂的颈前浅腹侧淋巴结和下颌淋巴结进行了检测，以确定是否存在[具体病原体未提及]。结果表明，这两种淋巴结都可能被[具体病原体未提及]污染；下颌淋巴结的[具体病原体未提及]感染率（<0.05）高于颈淋巴结（16%对0.91%），并且大多数（>90%）的[具体病原体未提及]分离株对一种抗菌药物敏感或耐药，而9.78%的分离株对三种或更多类别的抗菌药物耐药（多重耐药，MDR）。预防食源性疾病的干预方法可包括从猪肉产品中去除这些淋巴结，或仅将淋巴结纳入用于烹饪的产品中。需要制定综合多方面的干预方法以减少食物链中的[具体病原体未提及]。
