Not all vermiculite products contain asbestos, but some do. An EPA study showed some vermiculite products contain low levels of asbestos. Asbestos is found primarily in the unmixed vermiculite product although some was found in pre-mixed potting soils. For consumers using vermiculite on an infrequent basis the health risk is low. Greenhouse workers in daily contact incur a higher level of risk.
