A co-worker brought me food from her home. I ate it and afterwards regretted it. She let meknow she used to be a drug addict. My imagination got the best of me. Now I am worried that perhaps this person could have put her saliva in my food or God knows what kind of bodily fluid she could have put in my food and if she has an STD, let's say, Syphilis, Herpes, Gonoreah... all of them, can I get them from saliva in food? I am very worried and wish I never ate the food! This was 2 days ago (May 6, 2008).
