meatthermometer
Naturally steaks will be thinner than 4 inches like thermometer needle, at least the one I have. So it will absorb less heat in total, and maybe show lesser values than what is actually inside the meat.
Problem two, meat is less cooked in the middle so how is that adjusted with thermometers? Will it still accurately show that it is medium rare for example?
I understand the intent of the advice to always keep meat and vegetable preparation tools and areas separate is to establish a habit, to avoid the possibility of cross contamination in cases where you are not going to be cooking the vegetables as much or at all; and similarly in a catering environment to be able to visibly demonstrate that working practices are such that cross contamination cannot occur.
With thin cuts of meat (like chicken breast or a steak), you want to make sure you put the thermometer in to the thin side of the meat so that the whole thermometer goes in to the meat, rather than putting it in through the "top" so that only a little of the thermometer is in the meat. If you're putting it in the top, you can get wildly inaccurate temperatures. Also make sure that the thermometer isn't touching a pan, exposed to air, or touching a bone. Any of those can have a negative effect.
Also, you only need to cook chicken to 74C / 165F. That may be part of the problem in your case.
You may also want to check that your thermometer is accurate. You can stick it in boiling water to check that it reads 100C / 212F (assuming of course it goes up that high).

When taking the temperature of a thinner steak, I pick the steak up with a set of tongs and insert the thermometer into its side. Aim to position the tip of the probe in the coolest part of the steak - probably the center and away from the bone, if it has one.
Your goal is to find the coolest temperature inside the steak.
