Heparin probe finds U.S. tie to Chinese plant

The Wall Street Journal (subscription required), February 15, 2008

Baxter International Inc.'s investigation into the cause of deaths and allergic reactions linked to its blood-thinner heparin is focusing on variations in batches of the active ingredient for the drug, most of which were supplied by a Chinese manufacturing facility co-owned by a Wisconsin company. Baxter said the active ingredient for its heparin was supplied by Scientific Protein Laboratories LLC, a Waunakee, WI, company with a manufacturing facility there and a joint-venture operation called Changzhou SPL in Changzhou, China.
