Dunno, it's just a bad idea. The pathogens survive in the ground over winter, so I'm not surprised if they also survive in the compost. It's not only bacteria and viruses but also fungi. Best practice is to use pathogen free soil and compost, crop rotation. There is even a warning against composting rotten potatoes (related to tomatoes) for avoiding late blight.
