Currently less than .4% of the slaughtered pigs contain sulfamethazine at levels above those allowed by the Food and Drug Administration. These violations are due partly to failure to properly withdraw sulfamethazine after treatment to reduce loss or combat or prevent diseases, whereas others are due to inadvertent contamination of feed or the environment. Cull animals particularly are suspect. The National Pork Producers Council (NPPC), representing more than 100,000 producers, is supporting attempts to reduce violations and maintain the safe image of pork. The Food and Drug Administration is continuing to evaluate the safety of sulfamethazine, and the NPPC has encouraged producers to suspend use of the drug. The NPPC is encouraging development of faster, more reliable testing methods and of a traceback system to permit the farm of origin to be identified. But the NPPC is opposed to the "bill back" proposal developed by the Packers and Stockyard Administration that would allow packers to charge the seller for costs of carcasses condemned for containing illegal residues. Reasons for opposition include imprecision of current testing procedures, inaccuracy of present identification and traceback methods and disruption of the free market relationship between buyers and sellers.
目前，屠宰猪中含有高于美国食品药品监督管理局（FDA）规定水平的磺胺二甲嘧啶的比例不到0.4%。这些违规情况部分是由于治疗后未适当停用磺胺二甲嘧啶以减少损失或防治疾病，而其他情况则是由于饲料或环境的意外污染。尤其需要怀疑的是淘汰动物。代表超过10万生产商的美国全国猪肉生产者委员会（NPPC）正在支持减少违规行为并维护猪肉安全形象的努力。美国食品药品监督管理局正在继续评估磺胺二甲嘧啶的安全性，NPPC已鼓励生产商暂停使用该药物。NPPC正在鼓励开发更快、更可靠的检测方法以及追溯系统，以便能够识别生猪的原产地农场。但NPPC反对美国畜牧市场管理局提出的“费用追溯”提议，该提议将允许加工商向卖家收取因含有非法残留而被判定不合格的胴体的处理费用。反对的理由包括当前检测程序不精确、现有识别和追溯方法不准确以及买卖双方自由市场关系受到干扰。
