地沟油制药伤不起："地沟油"英语怎么说

有关当局发现制药厂用地沟油制药后，已经开始采取应对措施。国家食品药品监管局希望国内制药公司仔细检查原料来源，绝不能让有害物质混入药品中。

先看相关英语报导：
Authorities have stepped up measures against gutter oil after more pharmaceutical firms were found to have used the waste material.
The State Food and Drug Administration has told the country's pharmaceutical firms to carefully scrutinize their sources to prevent such ingredients being used in medicine.

分析：
上述报导中，"gutter oil"就是地沟油的意思，也可以译成illegal cooking oil或swill-cooked dirty oil。地沟油泛指在生活中存在的各类劣质油，如回收的食用油（cooking oil）、反复使用的炸油等。地沟油最大来源为城市大型饭店的隔油池，含有大量毒性物质，长期食用可能会引发癌症（cancer），对人体的危害极大。 近年来，地沟油丑闻不断曝光，放心食物越来越少，以致民众对食品安全的信心一再动摇。

例句：
1. Gutter oil is collected and refined from eatery offal,and it always contains animal fat.
地沟油是从餐饮业废弃物中提取的，成分复杂，常混有动物脂肪。

2. If the content of cholesterol was more than 0.05 mg/g, the vegetable oil was considered to have mixed with gutter oil.
使用这种方法，当食用植物油中掺有0.05毫克/克以上的地沟油时，即可检出。

3. Gutter oil refers to oil extracted from oily floats in the drain or leftover food from hotels or restaurants.
地沟油取自地沟中的浮油或宾馆、餐厅里的残渣剩饭。
