I misunderstood what you were saying – thank you for the clarification.
A couple of things that I could have expressed more clearly:
“when the seals of incoming merchandise are broken” – At what point and with which person(s) present should the seals be opened, not what to do if the seal is discovered to be broken.
“It is therefore necessary to consult someone who you know to be trustworthy with questions about hashgochos.” – applies to both a) and b) above. A blank line should have been inserted before this sentence for clarity’s sake.
