Cleaning Smell from Defrosted Freezer?

My freezer was turned off the other day for long enough for the meat to thaw but not go bad. The blood from the meat ran down the freezer sides. I thought I got it all because the freezer itself did not smell. Two days later and there is a terrible smell coming from near the freezer. I moved the big sucker and there is some blood that had found its way to the floor. There also appears to be some in a tiny metal tray supporting the internal components of freezer.

Now I cleaned all of the blood, dismantled the freezer inside and Lysoled and CLRed and scrubbed with all propose. The freezer doesn't stink, but behind the freezer and even down near the metal tray it smells like animal urine and rot. The copper lines that feed the inside coils enter the freezer is right where smell is coming from. I'm a loss at how to proceed. I just bought this thing. Thanks.
