One of my worst food related experiences.

I was building my house and I had just hooked up temporary water the night before. I used a big coil of 2" black plastic pipe that I had laying outside for a while and strung it across the ground. Water was running so I let it rung for a while and it looked clear and I quit for the day. The next morning I used my new water connection to make coffee. As I sat drinking my coffee I noticed some small lines floating on top. I looked in the other cups to see if something had settled in them - nope. I investigate everything I could think of until I finally went out to the pump and disconnected the pipe. In the end of the pipe I found a decomposing mouse. The specks in my coffee were mouse hairs
