For other readers: OJFord doesn't know what s/he's talking about and you should look up tests for the specific brands for the specific spices you're looking to buy, especially if you have children and/or you use spices liberally in your food.

Unfortunately it doesn't seem like there are brands that are across-the-board good on contamination.
