Trichinellosis and cysticercosis remain challenges to human health and animal productivity worldwide, especially in developing countries. While information on the occurrence of both diseases is infrequent, they are endemic in parts of Vietnam and mainly related to indigenous pigs kept by ethnic minorities. This study aimed to determine the seroprevalence and risk factors of both diseases in indigenous pigs and explore the perception and awareness of both human and pig trichinellosis and cysticercosis of pig farmers. A total of 352 pig sera samples from 131 holdings were collected and analyzed using ELISA antibody tests in six communes in the Da Bac districts of Hoa Binh province, Vietnam. A survey was conducted with representatives from these households to understand the knowledge and perspective on food-borne parasitic diseases. Overall, the seroprevalence of trichinellosis and cysticercosis was 13.6% (95% CI 10.2-17.7) and 1.7% (95% CI 0.6-3.7), respectively. The seroprevalence of trichinellosis was significantly higher in female and older pigs. Risk perception and knowledge of interviewed people on both human and pig trichinellosis and cysticercosis of pig farmers was poor. Risky practices, including free roaming of pigs and eating undercooked or fermented pork, were observed. Educational and awareness campaigns aligned with further research on feasible practice changes are critical to addressing these issues.
旋毛虫病和囊尾蚴病仍然是全球人类健康和动物生产力面临的挑战，尤其是在发展中国家。虽然关于这两种疾病发生情况的信息并不常见，但它们在越南部分地区呈地方性流行，主要与少数民族饲养的本地猪有关。本研究旨在确定本地猪中这两种疾病的血清流行率和危险因素，并探讨养猪户对人和猪旋毛虫病及囊尾蚴病的认知和意识。在越南和平省大叻县的六个公社，共收集了来自131个养殖场的352份猪血清样本，并使用ELISA抗体检测进行分析。对这些养殖户的代表进行了一项调查，以了解他们对食源性寄生虫病的知识和看法。总体而言，旋毛虫病和囊尾蚴病的血清流行率分别为13.6%（95%CI 10.2-17.7）和1.7%（95%CI 0.6-3.7）。旋毛虫病的血清流行率在雌性猪和老龄猪中显著更高。养殖户对人和猪旋毛虫病及囊尾蚴病的风险认知和知识较差。观察到一些危险行为，包括猪的自由放养以及食用未煮熟或发酵的猪肉。开展教育和提高认识活动，并进一步研究可行的做法改变，对于解决这些问题至关重要。
