how many rodent hairs are acceptable?

[Doug Henwood]

Spy quoted from this in the 80s, and Harper's did in its October 
issue, but it always makes good reading: the FDA's Food Defects 
Action Levels - and the beauty of the web is you can get the whole 
thing yourself: <http://vm.cfsan.fda.gov/~dms/dalbook.html>. less 
than 10mgs of mammalian excreta per pound of cocoa beans, fewer than 
30 fly eggs per 100g of tomato paste, fewer then 13 insect heads per 
100g of fig paste are of no danger to human health....
