Did you know that Southern Grove brand peanuts "contain tree nuts[?]" I've always heard that it's normal for nut producers to use common machinery to package nuts, which leads to cross-contamination, but the more I learn about the chain of supply, the less this makes sense to me. for example, cashews take incredible amounts of on-site (with respect to the plantations) labour to process and prepare the nuts for consumption (this is an extreme example considering the dangers of raw cashews, but it illustrates the point well). Why not just bottle them on-site as well? With efficient container design, the additional shipping costs per unit of product could be outweighed by the prospect of removing the "may contain traces of other nuts" from the label!
