Organochlorine pesticides (OCPs) are ubiquitous environmental contaminants widely used all over the world. These chlorinated hydrocarbons are toxic and often cause detrimental health effects because of their long shelf life and bioaccumulation in the adipose tissues of primates. OCP exposure to humans occurs through skin, inhalation and contaminated foods including milk and dairy products, whereas developing fetus and neonates are exposed through placental transfer and lactation, respectively. In 1960s, OCPs were banned in most developed countries, but because they are cheap and easily available, they are still widely used in most third world countries. The overuse or misuse of OCPs has been rising continuously which pose threats to environmental and human health. This review reports the comparative occurrence of OCPs in human and bovine milk samples around the globe and portrays the negative impacts encountered through the long history of OCP use.

有机氯农药 (OCP) 是普遍存在的环境污染物，在世界各地广泛使用。这些氯化碳氢化合物是有毒的，并且由于它们的长保质期和在灵长类动物脂肪组织中的生物蓄积性，通常会对健康造成不利影响。OCP 对人类的暴露是通过皮肤、吸入和受污染的食物（包括牛奶和奶制品）发生的，而发育中的胎儿和新生儿分别通过胎盘转移和哺乳暴露。在 1960 年代，大多数发达国家都禁止使用 OCP，但由于价格便宜且易于获得，因此在大多数第三世界国家仍然广泛使用。OCP 的过度使用或误用不断上升，对环境和人类健康构成威胁。
