Good manufacturing practice and out-of-specification testing controversy
Barr became involved in a controversy concerning alleged violations of current good manufacturing practice rules and the handling of out-of-specification laboratory results. The dispute led to litigation, and a 1993 loss for Barr contributed to later industry interpretations of FDA expectations for investigating and documenting such results.
