It’s not easy for nut processors to ensure food safety or meet customers’ product specifications. For one thing, foreign material and shell fragments can get into the processing line’s product stream. For another, nuts can be damaged by both by external and internal defects which can be almost impossible to detect. There’s also the risk posed by allergens if one type of nut should unintentionally get mixed with another. Yet all of these threats have to be eliminated to protect processors and retailers from product recalls and reputational damage.
