This sounds about right to me......
Can't eat beef......mad cow.
Can't eat chicken......bird flu.
Can't eat eggs......again, bird flu.
Can't eat pork......fears that bird flu will infect piggies.
Can't eat fish......heavy metals in the waters has poisoned their meat.
Can't eat fruits and veggies......insecticides and herbicides.
Hmmmmm! I believe that leaves Chocolate!!
