1 - If the fork/spoon was used before, maybe, but how likely is this really?
2 - Herpes doesn't live on the ground. I'm not sure I understand your question entirely - are you asking if the pacifier could get herpes on it from the floor, then get transferred to the wipe, then to the baby? That's not ever going to happen.
Herpes requires a few things to transmit. Usually, it's direct contact, like skin-to-skin contact - kissing (mouth-to-mouth skin contact), mouth to genital, genital to genital. It can be transmitted by sharing utensils or drinks, but that requires it going from their mouth to your mouth pretty quickly. This isn't like someone used a fork to test the food, then an hour later, gives you the fork for your meal. (And let's be real - most people don't do that.)
This sounds like a decent case of herpes anxiety. I understand fully not wanting baby to be exposed to things found on the ground, but maybe carry a few extra pacifiers for cases like this. Herpes doesn't ever infect like this, though.
Oral herpes type 1 is very, very common - about half the adult population has it. You might. About 90% never get a cold sore, so they don't know they have it. You can ask your doctor for a type specific IgG blood test to find out if you have it. If you have it, you can't get it again.
If this is anxiety, talk to your doctor. And talk to your baby's pediatrician about things that may harm him/her, and what won't.
