ELI5:If you left a piece of steak by itself in space, would it rot?

In case the title is confusing: If placed in a vacuum, would raw meat turn bad or would it stay perfectly edible? What factors would play into this?

Some bacteria need very little to live. Any of these bacteria already living in the meat would be able to decompose some of it, for a little while. However, the small percentage of these bacteria, coupled with the *extreme* coldness of space would make any such decomposition virtually unnoticeable. More importantly, the water in the meat would boil from the low pressure and the steak would essentially become freeze-dried. 

Could you eat it? ... .... .... probably.
