Meat that glows in the dark!

I was rather surprised last night when feeding our dogs to notice that several bones and pieces of meat were glowing with little pinpricks of light all over them. It would have been easy to jump to the conclusion that the meat was radioactive or had been contaminated with phosphorus, but then I remembered that such glowing is caused by the harmless Pseudomonas fluorescens bacteria. It's just a sign that the meat has probably passed its use by date!
It would be interesting to see how much of the meat we consume actually glows - but most of us will never know as we normally prepare our meals with the lights on.
