translation.en: So, this is sold as cow, but what happens when you slaughter a cow -- at least in industrial factory farming -- they have all these little bits of steak left that they can't actually sell as steak, so what they do is they glue them all together with fibrin from pig blood into this really large sausage, then freeze the sausage, cut it in little slices and sell those as steak again.
translation.zh: 在牛肉区出售， 然而，事实上，当一头牛被宰杀之后 -- 至少在屠宰场里是这样的情况 -- 会剩下零碎的牛排肉 但是这些碎肉又不能作为牛排出售， 于是，屠宰场就用猪血中提取的纤维蛋白 把这些碎肉粘在一起 制成一个硕大的肉肠， 把它冷冻，再切成小片 最后把这些肉片作为牛排出售。
