MO people with whom I am acquainted would NEVER order from Ben’s Deli.
Hebrew National was never treif meat in the past. I know personally the son (a Rov)of the former Rav Hamachshir). He always asserted that his father said that there was absolutely nothing intrinsically unkosher about Hebrew National, although it certainly was not a glatt hechsher. Those who were makpid on glatt at the time, would not eat it, but would not have been eating tarfus if they did.
Nowadays, the rov is gone, and I would not rely on what he said in the past. But at least 30 years ago, he stated it was kosher schechitah and kashering of the meat. BTW, I never used Hebrew National products at any time, but those who did, were not chayav on treif.
