simple grilling question

[space-time]

when I put the meat on the hot grill, I use that huge tweezers (how are they called anyway?) and now it may have some bacteria from the meat. I put the plate or bowl in the dishwasher, but I need the "tweezer" to flip the meat over halfway and to take it out when done. Of course, when done I use a new clean plate.

So what is the proper way to avoid getting sick from bacteria? do you guys wash the utensils after putting the meat on the grill, or do you just ignore it? do you have 2 sets of utensils? one to put the raw meat on the grill, and another one to take it out?
