Stockpiled Almonds – All About Mold and Moisture Control
Almond Board |

 Stockpiles have long been a way of life for the almond industry, and proper management is critical to prevent aflatoxin contamination. Nut contamination actually begins in the orchard as molds which produce aflatoxins are common in nature. Molds are found in the soil and in mummy nuts infested with the Navel orangeworm pest. Contamination levels beyond allowable levels can lead to nut rejection in the marketplace. Research funded by the Almond Board of California suggests that certain conditions in stockpiled almonds can increase the risk of growth and spread of Aspergillus spp, the fungal molds that cause aflatoxins. The Almond Board is funding research to establish a threshold and develop management guidelines for specific allowable kernel moisture content and temperature in stockpiles.
