Is your shea butter free of impurities?

I love your shea butter soap and am interested in your other shea butter products and have a question about your shea butter. I read that high quality shea butter is lab tested to make sure there are no impurities such as lead, mercury, mold, yeast, coliform bacteria (shigella, Ecoli, salmonella etc.) and that the highest quality is grade A. Is the shea butter used in your soap and other products lab tested for these impurities and is it grade A? I know it is organic certified but something could be organic and have these impurities. Thank you.

Our shea butter is certified to organic food standards. It is first extracted by water, women and wood in West Africa. Then it is shipped to Europe where it is low heat pasteurized, mixed and dewatered and filtered (again per USDA organic regs). Then it is organically refined, which means pushing it through a tube full of clay under pressure, then neutralizing it with organic citric acid. This process insures that the latex inherent in shea butter is completely removed. The final batch is thoroughly tested as if it were for food use.
