- Unauthorized NSF-ISR mark being applied to certificates and wallet cards
- Unauthorized use of the NSF-ISR mark is being applied to certificates and wallet cards after trainings are completed, which appear to be issued by the individual subcontractor David Rogerson. NSF is unable to confirm this individual is affiliated with NSF-ISR at this time and therefore such documents are not authorized to bear the NSF-ISR mark or make any claims of NSF-ISR registration.
