According to the egg board, only high heat pasteurization will kill it. These are unsafe per the HD, egg board, and the FDA. Look it up. Do not get your food safety tips from this site. There are the egg board, dairy board, .gov sites, and the FDA site that will answer all questions. Also a quick call to your local HD will show you just how dangerous this practice actually is.
Be sure you understand what you are doing. These products can be fatal in the highly succeptible groups. And people don't know in advance if they are succeptible. This is why people don't do this. Cute, but deadly.
I hope people will not just look at your cute picture and not read the thread, because threads like this are a hazard to public health.
There was a similar thread about baked goods in egg cartons. Same thing.
I would like to suggest that the OP have this thread removed.
