Avoiding Drug Shortages With Microbial Detection
Over the past year, critical drug shortages used to treat a host of life-threatening illnesses have been making headlines. Microbial contamination has been cited as a major contributor to the shortage, yet the prevailing practices to ensure the safety of drugs have been slow to change. In most cases, quality assurance practices safeguarding the drug making environment continue to rely on periodic air and a culturing method from a prior century.
