More on Faux Heparin Contaminant

According to the FDA, the chemically modified chondroitin sulfate found in lots of Baxter's recalled heparin made up as much as 50% of the product's raw ingredient, reports today's Chicago Tribune. The source of the faux heparin, derived from animal cartilage, is currently unknown; however, an expert suspects that the contaminant was deliberately put into Baxter's product, given that it was found in most batches (20 of 28) of the Chinese supplier's samples.
