The animal health hazards associated with the importation of pork and pork products include four viral agents: foot and mouth disease, classical swine fever (hog cholera), African swine fever, and swine vesicular disease viruses. The safety of importing pork from a zone infected with one or more of these diseases can be adequately determined only through risk assessment. This also applies for the safety of importing pork products which have undergone some form of processing (fully cooked pork products are not counted here). For each disease, the agent (pH and temperature lability), target organs, agent survival in pork and pork products, and agent quantification are discussed. Agent quantification is an input of the risk assessment which measures the viral titres in waste pork and pork products in relation to the oral infective dose estimated for each disease. Two other viral diseases, transmissible gastroenteritis of pigs and porcine reproductive and respiratory syndrome, are presented to illustrate why these two diseases are not hazards when associated with pork and pork products.
口蹄疫、经典猪瘟（猪霍乱）、非洲猪瘟和猪水疱病病毒。只有通过风险评估才能充分确定从感染一种或多种这些疾病的地区进口猪肉的安全性。这也适用于进口经过某种形式加工的猪肉制品的安全性（此处不包括完全煮熟的猪肉制品）。针对每种疾病，讨论了病原体（对pH值和温度的稳定性）、靶器官、病原体在猪肉及猪肉制品中的存活情况以及病原体定量。病原体定量是风险评估的一项输入内容，它测量废弃猪肉及猪肉制品中的病毒滴度与每种疾病估计的经口感染剂量的关系。还介绍了另外两种病毒性疾病，即猪传染性胃肠炎和猪繁殖与呼吸综合征，以说明为什么这两种疾病与猪肉及猪肉制品相关时不构成风险。
