Just noticed a post over on the Centers for Disease Control and Prevention
http://blogs.cdc.gov/publichealthmatters/2011/05/preparedness-101-zombie-apocalypse/ (Warning may take a while to load)
This is also linked from the main CDC website down on the right side of the page under News & Events.
Now I am wondering if the other US Government Agencies such as the Federal Emergency Management Agency (FEMA) will be following suit and posting about what they plan on doing in case of a major Zombie Outbreak.
