  10. 10. Mycotoxins Mykes: Greek for fungus/mold Toxicum: Latin for poison/toxin
  11. 11. Mycotoxins of economic, health and agricultural significance Mycotoxins are metabolic products of food spoilage fungi that induce toxic responses when consumed by animals or people. Hundreds of mycotoxins have been identified; They will fall into many different chemical classes, and induce a wide variety of toxic responses.
  12. 12. Figure 6.1. Factors affecting mycotoxin occurrence in the food chain (Pestka and Casale, 1989). Mycotoxins economic and health risks Biological Factors Susceptible Crop + Compatible, Toxigenic Fungus Environmental Factors Temperature Moisture Mechanical Injury Insect/Bird Damage Fungus Harvesting Crop Maturity Temperature Moisture Detection/Diversion Storage Temperature Moisture Detection/Diversion Distribution-Processing Detection/Diversion Animal ProductsHumans Animals
  13. 13. Ecological parameters affecting mycotoxin production Moisture Spore Load Temperature Competing Microflora Substrate CO2/O2 Time Mechanical Damage Insect Damage
  14. 14. Adverse economic effects of mycotoxins producer costs LIVESTOCK (beef, swine, poultry) and dairy • Higher mortality rates • Reproductive failures (abortions) • Reduced feed efficiency • Overall quality loss • Lower milk production • Nonmarketable milk CROPS • Yield Losses • Restricted Markets • Increased production costs • Increased post harvest costs
  15. 15. Aflatoxin • Produced by Aspergillus flavus and A. parasiticus • Five key aflatoxins: B1, B2, G1, G2 and M1 • Found in corn, grains, cottonseed, peanuts, tree nuts, spices, milk • Liver damage • IARC- class 1 human carcinogen

  17. 17. Aflatoxin B1
  18. 18. Effects of aflatoxins Figure 2.2 Livers from guinea pigs given increasing doses of aflatoxins over the same period of time. From left to right beginning in the upper left corner to the lower right corner with a liver from a guinea pig given the greatest dose of aflatoxins. Note the increasingly pale livers with increasing dose of aflatoxins. Photograph courtesy of J.L. Richard, USDA, ARS, National Animal Disease Center, Ames, Iowa.
  19. 19. Aflatoxin B1 Courtesy of D.P.H. Hsieh, University of California, Davis. Drawing by G. Hedberg, USDA, ARS, National Animal Disease Center, Ames, Iowa. Aflatoxin B1 binds to DNA at the guanine base in liver cells, corrupting the genetic code that regulates cell growth. Out-of-control cells grow into tumors that eventually become cancerous.
