"If you’re someone who purchases bulk nuts, grains, etc. Just know that those bins are probably rarely cleaned, and even when they are “cleaned”, odds are they were just rinsed out/wiped down to look clean.
I used to be a bulk buyer at Whole Foods Market and when I took over our bulk department had no cleaning logs or sanitizing procedure. The bins had moths/insect colonies and mold in them. Our store was opened nearly 5 years prior. "
