This review summarizes evidence on food contaminants and cancer risk, highlighting agents like aflatoxin and alcoholic beverages with strong links. It details findings from major cancer risk assessment programs.

Area of Science:

  • Toxicology
  • Carcinogenesis
  • Food Safety

Background:

  • Dietary components can influence cancer risk.
  • Food contaminants are a significant area of research.
  • Major international and national programs evaluate carcinogenic potential.

Purpose of the Study:

  • To review and synthesize evidence on the carcinogenic potential of food contaminants.
  • To summarize findings from the International Agency for Research on Cancer (IARC) and the US National Toxicology Program (NTP).
  • To present the graded cancer risk posed by various agents to humans.

Main Methods:

  • Review of scientific studies and program evaluations.
  • Synthesis of data from IARC Monographs and NTP Report of Carcinogens.

  • Categorization of agents based on the degree of evidence for carcinogenicity.

    • Main Results:

    • Aflatoxin, alcoholic beverages, and 2,3,7,8-tetrachlorodibenzo-p-dioxin have the highest level of evidence for carcinogenicity.
    • Acetaldehyde, polycyclic aromatic hydrocarbons, and nitrosamines have moderate evidence.
    • Bracken fern, fumonisin B(1), and ochratoxin have low evidence.

    Conclusions:

    • Significant evidence links certain food contaminants to human cancer risk.
    • International and national programs provide crucial risk assessments for public health.
    • Continued research and monitoring of food contaminants are essential for cancer prevention.
