I fried a turkey, the cooking thermometer melted and dropped into the pot, is this dangerous to eat?

the turkey was frying in peanut oil, we are worried the glass vial containing mercury (or whatever other chemical is used) may have broken inside the pot with the cooking turkey.

Has mercury been banned in thermometers?

Has mercury been banned in thermometers, including cooking thermometers? If so, when?
How do you know if your thermometer has mercury?
My thermometer has red in the center of a glass tube? Is it mercury?
How do you safely dispose of these thermometers?
Thank you!
