Monitoring starts once the quality mark has been awarded. Again, a specific number of samples must be inspected in independent laboratories under the quality commission’s control depending on the type of product.
A specific number of external samplings is required. This external monitoring is a key mainstay of the quality assurance. The facility is also required to monitor and keep record of the production process at all times, as well as check each charge on site for key production parameters of the substrate produced, such as salinity and pH value (self-monitoring).
If a product fails to meet the quality assurance requirements, the quality commission is entitled to order repeat inspections to be made and to suspend or withdraw the quality mark if necessary.
