A new strain of Clostridium botulinum encoding a novel toxin, BoNT/H the eight such toxin, has been described, the first such toxin to be described in >40 years (Barash et al., 2014; Dover et al., 2014). 

The authors referred their concerns up the line. Journal editors and US security agencies were involved resulting in the publication of the work without description of the toxin itself. The original paper was published accompanied by a letter from the editors describing the review process and decision (Hooper & Hirsch, 2014), a historical overview of botulinum toxins (Popoff, 2014) and a comment from David Relman, former member of the NSABB and one who handled the original Kawaoka and Fouchier papers (Relman, 2014).

While the efficiency and merits of redacting essential data from a paper can be debated, the example is well worth reading for the authors flagged up their concerns and shared their observations and difficulties with other stakeholders. It shows that complex and worrying biological issues can be shared and acted upon. The accompanying review papers make for good reading.

A note at the end of the editor’s letter (Hooper & Hirsch, 2014) lists the large number of committees that were involved in commenting on the larger dimensions of theses findings.

“A committee representing various branches of the US government reviewed and approved submission of the manuscripts. Represented on this committee were the Drug Development Section, Division of Microbiology and Infectious Diseases, National Institute of Allergy and Infectious Diseases (NIAID), National Institutes of Health (NIH); the Enteric and Hepatic Diseases Branch, NIAID, NIH; the Bacteriology and Mycology Branch, NIAID, NIH; the Office of Biotechnology Activities, Office of Science Policy, NIH; the National Counterproliferation Center, Office of the Director of National Intelligence; the Office of the Assistant Secretary for Preparedness and Response, Department of Health and Human Services (DHHS); the Biomedical Advanced Research and Development Authority, Office of the Assistant Secretary for Preparedness and Response, DHHS; the Threat Characterization and Attribution Branch, Chemical and Biological Defense Division, Science and Technology Directorate, Department of Homeland Security; the US Army Medical Research Institute of Infectious Diseases; the Division of Select Agents and Toxins, Office of Public Health Preparedness and Response, Centers for Disease Control and Prevention, DHHS; and the Biological Countermeasures Unit, Federal Bureau of Investigation Weapons of Mass Destruction Directorate, Department of Justice.”

The last paragraph from Relman’s letter is worth reading.

“Finally, for voluntary controls to play a useful role in the management of problematic information in the “gray area,” scientists will first need to recognize their ethical and moral responsibilities to society in the pursuit of knowledge. Scientists have obligations to society that involve more than blind pursuit of information. Like clinicians, scientists have an obligation to do no harm.”
