A number of former employees of an animal-food flavoring maker have sued companies that make or sell the butter-flavoring chemical diacetyl, alleging that occupational exposure caused them to contract a debilitating lung disease known as bronchiolitis obliterans (or popcorn lung). Huerta v. Aldrich Chem. Co., Inc., No. 11-009461 (Ill. Cir. Ct., Cook County, filed September 9, 2011). The 112-count complaint alleges negligence, strict liability design defect and failure to warn, conspiracy, and loss of consortium. The plaintiffs seek unspecified compensatory damages. According to the complaint, “Defendants knew or should have known of the hazardous nature of their diacetyl and diacetyl-containing flavors both at the time of sale and when plaintiffs were exposed to such products while working at the Feed Flavors facility. [Yet], defendants failed to warn of the defective nature of their flavoring chemicals and failed to give instructions on safe use of the flavoring chemicals.”
