Sterigmatocystin is a carcinogenic compound that affects several species of crops and several species of experimental animals. The sterigmatocystin biosynthetic pathway is the best known and most studied. The International Agency for Research on Cancer classifies sterigmatocystin in the Group 2B. Three groups of analytical methods to determine sterigmatocystin in food can be found: chromatographic, ELISA immunoassays and chemical sensors. In addition, sterigmatocystin is a precursor of aflatoxin B1 in those cases where cereals and/or food are contaminated with fungi capable of producing aflatoxins. Chemical structures of sterigmatocystin and aflatoxin B1 are similar. These mycotoxins are pathogens of animals and cereals, producing a major economic impact on biotechnology and agricultural and food industries.This review summarizes different aspects related to sterigmatocystin such as its biosynthesis, toxicological studies and analytical methods for its determination.
