That's the problem - folks are now aghast if they find a blood spot in an egg, a caterpillar in their cabbage, etc etc. Just means everything has to be blitzed with pesticides etc. I have a friend who won't touch our free range eggs because they don't have little lions on them, but will quite happily buy battery eggs from the supermarket
. I told her it was because we hadn't had our hens had run out of ink, and I honestly think she half believed me!
I spent my early years in Zambia, where my parents had to sieve all the wholemeal flour to get rid of weevils. The white flour didn't have this problem, and my Dad assumed this was because it was more refined. A friend soon put him right though - "Oh, they can't live in the white flour - there's not enough nutrition in it for them!!"
