It's a pitty..

Certificates can be made by anyone who can handle a printer, pen and a stamp/photoshop.
I sometimes request safety related certificates from trough my work. If needed badly enough, they will somehow find it's way to the table within an hour. Usually with a stamp or language unknown to me. Anything can look authentic and good, but if it can't be traced, it's pretty worthless.
