Hello,
Today I found human blood on the wrapper of a sandwich I got from a fast food restaurant.I didn't notice at first I just took s few bites and when I put my sandwich down I noticed humanon blood on the inside of my wrapper. It was from one side to the other.I called the 1800 number on the bag at that moment. I thought of just pursuing it myself but I'm looking for advice. I just feel sick thinking about it.

How do you KNOW it was human blood ?
Could it of been burger juice or ketchup.
While you can sue for anything, winning is a different matter entirely.

Unless, you took the wrapper to a lab and had it tested, you cannot know what the stain was.

So what happened when you called the number?
