We’ve arrived at the fourth and final lab, which just so happens to be the busiest lab in quality assurance. Every raw ingredient and every finished product passes through this lab. In the Micro Lab, raw material and finished product samples are placed in a Petri dish or film where they sit in a medium that accelerates the potential growth of bacteria. If our experts find signs of harmful bacterium, such as E. coli, listeria, or salmonella, the raw material or product batch is rejected. Interestingly, after our testing and manufacturing machinery has been thoroughly cleaned, Synergy uses the Micro Lab to audit the machine’s cleanliness with a sterile swab. Then, the swab is incubated and inspected in the Micro Lab. Our cleaning procedures are validated when the swab proves to be bacteria free.
