Today I learned that most of the dried herbs and spices on our supermarket shelves are contaminated with, eg toxins such as lead, even salmonella! It can come from the soil at source, or unsanitary storage or packaging conditions. I checked my own extensive collection, not even one stated the origin of the contents. Guess what? I tossed them all out. I'm fuming. I will be ordering some online from a reliable, certified supplier - of which there are few.
