牛肉在口蹄疫方面的安全性取决于出口地区通过疾病流行构成的风险水平、该地区监测系统的可靠性、预防和控制措施的效力、兽医服务的效率和私营部门的支持。南美大陆已根据这些标准进行了区域化。今天，在500多万平方公里的领土上，大约有9000万头牛，其中包括在动物和动物产品出口方面被归类为口蹄疫风险非常低到很低的区域。另有5000万头牛生活在被归类为中等风险的地区。这些风险类别反映了不同程度的风险。南美肉类出口地区的牛肉收获包括一系列风险缓解措施，从来源牛群的来源到牛肉的最终包装。这些措施将不受限制的风险估计减少了近六个数量级。因此，来自南美低风险地区的牛肉全球贸易最终发生口蹄疫的风险极小。
The safety of beef with respect to foot and mouth disease (FMD) is determined by the level of risk which the exporting region poses through disease prevalence, the reliability of the surveillance system of the region, the efficacy of the prevention and control measures, the efficiency of the Veterinary Services and the support of the private sector. The South American continent has been regionalised in accordance with these criteria. Today there are approximately 90 million cattle in a territory of over 5 million km2 comprising regions classified as having a very low to low level risk for FMD with regard to the export of animals and animal products. Another 50 million cattle live in regions classified as posing a moderate risk. These risk categories reflect varying levels of risk. The harvest of beef in the meat-exporting regions of South America includes a series of risk mitigation measures, from the origin of the source herd to the final packing of the beef. These measures reduce the unrestricted risk estimate by almost six orders of magnitude. Therefore, the final risk of FMD for the global trade of beef originating from the low risk regions in South America is extremely small.
