I frankly think the rampant fear of bird flu is overated, yet the risk of some pandemic is undeniable.
When I first learned my culinary skills I was taught to crack an egg only on a flat surface -- so as not to drive the shell (which may be contaminted by fecal as well as other matter) into the edible part of the egg. In the last ten years I've seen near every TV chef violate this rule with the exception of Pepin.
Eggs are probably routinely washed before packaging, yet I will maintain my original practice.
