先看相關英語報導：
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：
上述報導中，"gutter oil"就是地溝油的意思，也可以譯成illegal cooking oil或swill-cooked dirty oil。地溝油泛指在生活中存在的各類劣質油，如回收的食用油（cooking oil）、反復使用的炸油等。地溝油最大來源為城市大型飯店的隔油池，含有大量毒性物質，長期食用可能會引發(fā)癌癥（cancer），對人體的危害極大。 近年來，地溝油丑聞不斷曝光，放心食物越來越少，以致民眾對食品安全的信心一再動搖。

例句：
1. Gutter oil is collected and refined from eatery offal,and it always contains animal fat.
地溝油是從餐飲業(yè)廢棄物中提取的，成分復雜，?；煊袆游镏?。

2. If the content of cholesterol was more than 0.05 mg/g, the vegetable oil was considered to have mixed with gutter oil.
使用這種方法，當食用植物油中摻有0.05毫克/克以上的地溝油時，即可檢出。

3. Gutter oil refers to oil extracted from oily floats in the drain or leftover food from hotels or restaurants.
地溝油取自地溝中的浮油或賓館、餐廳里的殘渣剩飯。
