Always strikes me as a bad idea to disturb such things. You never know what lies dormant inside.
Not long ago, archeologists opened an ancient Egyptian sarcophagus and found skeletons partly submerged in some red liquid of unknown origin which was eventually determined to be sewage from a nearby building mixed in with the human remains.
Bad as that was, there were people who thought it would be a good idea to drink that liquid.
