AOAC ISPAM Stakeholder Panel Meeting Book 9-24-17

Contaminant Grains ƒ As we have encountered in previous work, the decision on what contaminant grains to use in spiking studies is controversial. ƒ The age-old question is whether or not to use a single cultivar, or use a blend of common cultivars which are widely planted in the region. ƒ We have obtained several common rye and barley cultivars currently planted in North American oat regions for the study.

Contaminant Grains ƒ At the guidance of the Working Group, General Mills will be willing to blend these cultivars, or use them unblended to make spiking materials. ƒ For wheat spiking material, we were anticipating using the MoniQA wheat gluten flour material, but as yet, that has not been made available to us. ƒ If time is critical, we would be willing to source common wheat cultivars from our wheat breeder contacts and perform similar operations to develop a blend of wheats to use as spiking materials.
