Introduction: Consumption of grains, nuts dried fruits, spices and cow's milk is high globally elevated. These foods are susceptible sensitive to biological contamination, including that caused by fungi of the genus Aspergillus, which produce secondary toxic metabolites called aflatoxins, which cause adverse health effects. The aflatoxin B1 and M1 have been classified by the International Agency for Research on Cancer (IARC) in Group I as carcinogenic to humans. This article shows the occurrence of aflatoxins in some foods for human consumption and its relationship to the development of hepatocellular carcinoma. Methods: A bibliographic search was carried out in the databases: Science Direct, Scopus, Pubmed and Web of Science. Words like "risk assessment and aflatoxin", "occurrence and aflatoxins", "aflatoxins and hepatocellular carcinoma", "aflatoxins and foodstuffs" were used. Results: Based on the studies conducted it was demonstrated that the occurrence of aflatoxins is high, especially in cereals grains such as rice, corn, and wheat. In addition, research related to exposure assessment highlighted the link between frequent consumption of these mycotoxins and the risk of developing hepatocellular carcinoma, especially in people who have contracted hepatitis B virus. Conclusion: The high prevalence of aflatoxins in food has generated food security safety alarms worldwide. Although some regulations have been created, in countries where there is greater more exposure to these mycotoxins there is little or no quality control. It is Therefore, it is important to create relevant monitoring mechanisms so that the to reduce the risk of fungal contamination and food with aflatoxins. possible cases of liver cancer may be lower.
