A 2019 study Abdul-Shaheed et al in the International Journal of Poultry Science, has shown that an alarming 88-94% of eggs they tested in Iraq were contaminated with mycotoxins fumonisin and zearalenone. This result is in contradiction to a 2016 study from Korea*, in which no eggs tested were contaminated. In the former paper, it was noted that laying hens have a very long rearing period, during which they are at risk of chronic exposure to mycotoxins in contaminated feed. One potential explanation of the discrepancies of the study results could be due to the difference in mycotoxin contamination of the hen feed.
High humidity, warmer temperatures and a high moisture content are all factors that stimulate fungus growth and, mycotoxin production. As our local climates change and weather events become more extreme we are exposed to an increased risk of mycotoxin contamination of our food both directly, through crops we consume, and through bioaccumulation in animal products. Strict regulation and enforcement through analytical testing of mycotoxins in food and feed is paramount.
