Hello NSF 456 Members & Observers, Again, congratulations on helping get this standard approved. It will be of great benefit to the public health sector. We now move into maintenance mode (as you know this is a living document which will be continuously updated). While we have not met in person for some time, I wanted to remind all members and observers of the confidentiality obligations each of you have in connection with your service on and participation in this Joint Committee. Please make sure you keep all work and materials transmitted and received confidential, including refraining from using these materials or this process in any competitive manner. These are basic tenets of maintaining independence, impartiality, and integrity of this important public health initiative. Thank you all for your help and input over the years. I look forward to seeing all of you soon.
