Cripe another "the sky is falling" thread and a chance for "holy than thou" posts. My understanding is that the contaminate feed was the result of poor quality control in the process by which the feed at two farms was handled allowing rat feces to get in the feed coupled with really lousy conditions at the farms. This was not a commercial feed operation per se but an "in house" processor--in short it was a giant "doing my own feed mixing" operation. Sure your feed could become contaminated with salmonella, pesticides, antibiotics or parts of human anatomy but you could also be hit on the head with a meteor--stop worrying, know your sources and eat your eggs. From a 72 -year prospective I can tell you that there are a lot of things to worry about and if you let them run your life, you'll never do anything.
As a case in point: My mother worried to the point of hysteria about dying from drowning, snake bite or in an automobile accident. She passed quietly in bed at 99.
