Postmortem data for harbor seals (Phoca vitulina richardsii) in the Salish Sea were analyzed for epidemiologic trends in congenital diseases. Cleft palate, cleft lips, or both (n=8) and cardiac defects (n=5) were the most common congenital abnormalities, followed by cases with multiple defects (n=4). No temporal trends or spatial clusters of cases were seen from 2003 to 2019, during which time monitoring effort was consistent. Cases could not be linked to specific causes such as environmental contamination or maternal malnutrition. Our study suggests that a yearly prevalence of 2.9%±2.2 is the endemic level of congenital disease in this stable harbor seal population. Continued monitoring of birth defects and overall harbor seal population status could help to identify emerging teratogens.
对在萨利希海（Salish Sea）死亡的港海豹（Phoca vitulina richardsii）的尸检数据进行了分析，以了解先天性疾病的流行病学趋势。最常见的先天性异常是腭裂、唇裂或两者都有（n=8）和心脏缺陷（n=5），其次是有多种缺陷的病例（n=4）。在 2003 年至 2019 年期间，没有发现病例的时间趋势或空间聚集，在此期间监测工作是一致的。无法将病例与环境污染或母体营养不良等特定原因联系起来。我们的研究表明，在这个稳定的港海豹种群中，每年 2.9%±2.2 的流行率是先天性疾病的流行水平。对出生缺陷和整体港海豹种群状况的持续监测有助于识别新出现的致畸物。
