The application of biosecurity measures in pig farms has prompted a shift in epidemiological reality, altering the risk profile attributed to the consumption of pork. The inspection of pig carcasses in Brazil is based on incisions and palpations to seek lesions mainly related to classic zoonotic diseases. We describe the use of a qualitative risk assessment from the farm to the table to characterize the risk of foodborne disease caused by biological hazards to humans due to the consumption of pork. The model was adapted from the Codex Alimentarius and comprises four steps: (I) hazard identification, (II) hazard characterization, (III) exposure assessment, and (IV) risk characterization. The exposure assessment step considers the release of hazards at a pre-harvest level (i.e., swine in herds) and the amplification or reduction of the release during the procedure to obtain pork from a carcass. Risk characterization is classified into five levels, from very low to very high. No hazard had very high risk, Salmonella sp. [nontyphoidal] had high risk, no hazard had moderate risk, seven hazards had low risk, and other hazards had very low risk. When the initial release was increased, the risk for hazards with higher adverse effects (e.g. C. botulinum, B. suis, and E. coli [STEC]) increased to very high or high. The uncertainty was very high for seven hazards and very low for three. These findings can help the Brazilian Ministry of Agriculture discuss changes in the routine inspection of the carcasses of pigs raised in industrial systems in Brazil.

生物安全措施在养猪场中的应用促使流行病学现实发生了变化，改变了由于食用猪肉而引起的风险状况。巴西的猪car体检查是根据切口和触诊进行的，以寻找主要与经典人畜共患病有关的病变。我们描述了从农场到餐桌使用定性风险评估来表征因食用猪肉而对人的生物危害引起的食源性疾病的风险。该模型改编自食品法典包括四个步骤：（I）危害识别，（II）危害特征描述，（III）暴露评估和（IV）风险特征描述。暴露评估步骤考虑了在收获前水平释放危害（即猪群中的猪）以及在从a体中获取猪肉的过程中释放的放大或减少。风险描述分为五个级别，从非常低到非常高。无危害有很高的风险，沙门氏菌属。[非伤寒]具有高风险，无危害具有中度风险，七个危害具有低风险，其他危害具有非常低的风险。当初始释放量增加时，具有较高不良反应的危险（例如肉毒梭菌，猪双歧杆菌和大肠杆菌）的风险[STEC]）增加到很高或很高。对于七个危害，不确定性很高，而对于三个危害，不确定性很低。这些发现可以帮助巴西农业部讨论对巴西工业系统中饲养的猪的尸体进行例行检查的变化。
