Feature Article: Resolving the Source of Foreign Matter in Formulations

The identity and source of foreign matter can be contentious since it may impact the release of a product, trigger recalls, or result in disputes between suppliers, manufactures, and insurance carriers. Since foreign matter in bulk powders can originate at virtually any stage of production, source attribution can be both complex and challenging. Regardless of the type of investigation, the first goal in any alleged foreign matter incident is to identify it with certainty. Contaminant materials can consist of almost anything you might imagine, and many things you probably couldn’t.
