Nitrofen is an herbicide of the diphenyl ether class. Because of concerns about its carcinogenicity , the use of nitrofen has been banned in the European Union [2] and in the United States since 1996. [1] [3] It has been superseded by related protoporphyrinogen oxidase enzyme inhibitors including acifluorfen and fomesafen .
In 2002, Nitrofen was detected in organic feed, organic eggs, and organic poultry products in Germany prompting a scandal which caused a decline in all organic meat sales in Europe. [4] [5]
Nitrofen is listed as an IARC Group 2B carcinogen , meaning it is "possibly carcinogenic to humans". [6]
