It certainly looks like you've got a contamination, but if it tastes okay at the moment you can probably package. What's your gravity? Remember that 0.003 is all the gravity you need for full carbonation. A lot of microorganisms that can contaminate beer have the potential to consume sugars, so then may overcarbonate over time. I'd store them carefully (in a box, wrapped in a trash bag away from anything important) and be prepared to consume quickly. Whether you keep the bottles afterwards is up to you - I do, but I generally know what I put in there.
You can rack and bottle as normal, but be prepared to take extraordinary measures cleaning the equipment after you bottle, as I'm assuming you don't want this to become your house culture.
