Seven years after the release of the BMBL 5th Edition, NIH and CDC are considering a revision based on the comments of a broader set of stakeholders. At the request of NIH, the National Academies of Sciences, Engineering and Medicine conducted a virtual town hall meeting from 4 April to 20 May 2016 to allow BMBL users to share their thoughts on the BMBL in general and its individual sections and appendices. Specifically, users were asked to indicate what information they think should be added, revised, or deleted. Major themes from the virtual town hall meeting were further discussed in a workshop held on 12 May 2016 in Washington, DC. This document encapsulates the discussion of the major comments on the BMBL that were posted on the virtual town hall prior to 12 May 2016 and the various BMBL comments and issues related to biosafety that were raised during the workshop by participants who attended the meeting in Washington DC and those who listened to the live webcast.
