Peter Dillon asked?

No - but not sure that I have looked that carefully.  For EFB I would 
usually look at the gut.  If yellow OK, if white suspect EFB and look at 
under the microscope for bacteria.

Neglected brood usually does not have a yellow gut - because it is not being 
fed - but laying workers/neglected brood would not normally lead me to 
suspect EFB - they look so different.
Best wishes
