The answer to that question is: People aren't as educated about the dangers from other meat. They aren't as obvious or single-minded as salmonella on chicken, so idiot normies forget the risks and think it's OK because worms and other diseases aren't as obviously bad as a direct gamble with death.

TL;DR, the risks are less obvious and often less severe, and normies think "less" means, "ok", because they're dumb.
