r C< SUMMARY
Although direct proof that aflatoxins (B^ B2, G^, G2) induce
cancer in humans does not exist, laboratory tests have demonstrated
that they are animal carcinogens. Further, epidemiology studies in
Thailand and parts of Africa show a significant relationship between
liver cancer incidence and estimated levels of aflatoxin intake.
Aflatoxins. cannot be completely eliminated from food products
without eliminating the-products themselves. FDA has been enforcing
a limit of 20 parts per oiilion (ppb) for aflatoxins in certain foods
and is considering reducing that limit to 15 ppb for peanuts and peanut
products (39 FR 42748).
Unfortunately,' the direct risks, if any, to humans from ingestion
of aflatoxins cannot be measured. Therefore, risk assessments must
rely on mathematical treatment of animal toxicology and epidemiology
studies. Such risk assessments have been made by FDA and are described
herein.
Aflatoxins can occur in a variety of grains and nuts and can also
occur in the meat, milk, and eggs of food animals that have consumed
aflatoxin-containing feeds. Corn products and peanut products only
have been considered in the risk calculations since inclusion of
other products, because of contamination levels and/or frequency of
contamination or consumption does not significantly affect the
numerical results. Emphasis has been placed on com products in the
Southeastern United States because both consumption and aflatoxin
N
j- v
contamination levels are relatively high in that region.
