Feeling secure? Well don't #20

Anthrax
What you can't see can kill you.

American laboratories handling the world's deadliest germs and toxins have experienced more than 100 accidents and missing shipments since 2003, and the number is increasing steadily as more labs across the country are approved to do the work.

No one died, and regulators said the public was never at risk during these incidents. But the documented cases reflect poorly on procedures and oversight at high-security labs, some of which work with organisms and poisons so dangerous that illnesses they cause have no cure. In some cases, labs have failed to report accidents as required by law.

I showed you a microscopic picture of anthrax. I couldn't bring myself to show you pictures of those infected. It ain't a pretty sight.
