I have been searching for the name of this movie for so many years with no results. I can just remember bits and pieces. A man found out some secret information that he wasn't supposed to know, so another man broke into his home and placed a poisonous chemical in his toothpaste. When he brushed his teeth the chemical made him explode.
Additionally, I remember mutilated cows and an underground facility. Please help its been driving me crazy for years!
